They can also be a good way to get magnesium and vitamins C and B6.

and help with production of white blood cells all due to the high level of Vitamin b6 that bananas contain she told Live Science.

1 medium banana (4. 5 oz/126 g) Calories 110 Calories from Fat 0*Percent Daily Values(%DV) are based on a 2000 calorie diet.

Plus Vitamin b6 can help you sleep well and magnesium helps to relax muscles. Bananas are high in fiber

Vitamin b6 can also help protect against type 2 diabetes and aid in weight loss according to Flores.

The fruits contain a small but significant amount of Vitamin a which is essential for protecting your eyes maintaining normal vision and improving vision at night according to the National institutes of health.

Vitamin a contains compounds that preserve the membranes around your eyes and are an element in the proteins that bring light to your corneas.

Like other fruits bananas can help prevent macular degeneration an incurable condition which blurs central vision.

They also do not contain enough fat or protein to be a healthy meal on their own or an effective post-workout snack.

Eating bananas becomes significantly risky only if you eat too many. The USDA recommends that adults eat about two cups of fruit a day or about two bananas.

If you eat dozens of bananas every day there may be a risk of excessively high vitamin and mineral levels.

According to the NIH consuming more than 500 milligrams of Vitamin b6 daily can possibly lead to nerve damage in the arms and legs.

You would have to eat thousands of bananas to reach that level of Vitamin b6. It turns out that the biggest risk from a banana peel might really be slipping on it.

It contains high amounts of Vitamin b6 and B12 as well as magnesium and potassium. It also contains some fiber

and protein According to a 2011 article in the journal of Applied Biochemistry and Biotechnology banana peels also have various bioactive compounds like polyphenols carotenoids and others.

The treatment involved a pig bladder that had been stripped of its cells leaving only a scaffold made of tough proteins.

In the study the protein scaffold that holds the cells of a pig bladder in place worked by attracting stem cells to the site the injury

This would ensure that the protein scaffold had the effect the doctors were seeking and any healing they saw was not due to some other factor.

It occurs because proteins found in some fresh fruits and vegetables are similar to allergy-causing proteins found in pollens such as ragweed birch mugwort and grasses.

Not long after some people with seasonal allergies eat uncooked fruits and raw vegetables as well as some nuts and spices these people's immune systems recognize a similarity between the food and pollen's proteins.

This is called cross reactivity. The thinking in the field is that the pollen allergy is the driver behind the immune response to the food said Dr. Wayne Shreffler director of the Food Allergy Center at Massgeneral Hospital for Children in Boston.

That's because the food's allergy-causing protein is broken easily down by cooking or processing.

And of course oranges are well known for their Vitamin c content said Laura Flores a San diego-based nutritionist.

1 medium orange (5. 5 oz/154 g) Calories 80 Calories from Fat 0*Percent Daily Values(%DV) are based on a 2000 calorie diet.

Immune system Most citrus fruits have a good deal of Vitamin c and oranges have high levels even compared to their tangy brethren.

Vitamin c protects cells by scavenging and neutralizing free radicals explains a 2010 article in the medical journal Pharmacognosy Reviews.

Vitamin c also helps keep skin looking beautiful by helping fight against skin damage caused by the sun and pollution.

It is vital to collagen production and may help reduce wrinkles and improve the skin's overall texture according to the Cleveland Clinic.

Oranges contain Vitamin c fiber potassium and choline which are all good for your heart so the fruits may give your ticker a big boost.

She noted another heart-related benefit pointing out that oranges are high in folate which is beneficial in lowering levels of homocysteine a cardiovascular risk factor.

and improve blood sugar lipids and insulin levels in people with type 2 diabetes. The American Diabetes Association lists oranges along with other citrus fruits as a superfood for people with diabetes.

Oranges are Vitamin a rich. This nutrient contains carotenoid compounds like lutein beta-carotene and zeaxanthin which can help prevent age-related macular degeneration an incurable condition that blurs central vision.

Vitamin a also helps your eyes absorb light and it improves night vision. Furthermore the American Optometric Association reports that Vitamin c can help reduce the risk of cataracts

and may slow the progression of macular degeneration. The Vitamin c in oranges is associated with a reduced risk of colon cancer due to preventing DNA mutations from taking place Flores said.

Studies have shown that about 10 to 15 percent of colon cancers have a mutation in a gene called BRAF.

It is also possible to have too much Vitamin c (more than 2000 mg a day. An excess of this nutrient may lead to diarrhea nausea vomiting heartburn bloating

Additionally orange peels contain vitamins A c B6 and B5; calcium; riboflavin; thiamin; niacin; and folate. One way to get some of the nutrients is by eating the inner part of the peel and leaving the tough outer part.

The pith of the orange the white part between the skin and fruit can be sour

or bitter but actually contains just as much Vitamin c as the fruit itself with a good deal of fiber Flores said.

The orange-fleshed tubers are especially high in Vitamin a (also called beta-carotene which is the carotenoid that turns into Vitamin a) vitamins C E and B6 fiber and manganese.

They even contain some iron. Plus they re fat-free relatively low in sodium and have fewer calories than white potatoes

Sweet potatoes are one of the best Vitamin a sources out there containing more than 100 percent of the daily recommended intake.

Vitamin a is an antioxidant powerhouse and beta-carotene has been linked to anti-aging benefits cancer prevention and helping maintain good eyesight.

While the orange and yellow types contain the most Vitamin a the purple sort is an excellent way to get antioxidants.

1 medium (4. 6 oz/130 g) Calories 100 Calories from Fat 0*Percent Daily Values(%DV) are based on a 2000 calorie diet.

Heart health Sweet potatoes are a great source of B6 vitamins which are brilliant at breaking down homocysteine a substance that contributes to the hardening of blood vessels and arteries.

Immunity and anti-inflammatory properties One sweet potato contains about half our daily recommended intake of Vitamin c.

Vitamins A and E also support a healthy immune system and are powerful disease-fighting antioxidants.

While orange sweet potatoes contain more Vitamin a purple sweet potatoes are packed with the antioxidants cyanidin and peonidin All of these pigment-related antioxidants have excellent anti-inflammatory benefits

Skin and hair Vitamin a can help protect against sun damage and vitamins C and E are well-known beauty supplements.#

#They encourage healthy glowing skin and collagen growth. Digestion Sweet potatoes are a good source of dietary fiber

which aids in maintaining a healthy digestive tract and helps keep you regular. Cancer prevention The NIH reports that some studies have suggested that beta-carotene may reduce the risk of breast cancer in premenopausal women ovarian cancer in postmenopausal women.

While the Vitamin a in sweet potatoes has numerous benefits if consumed in daily abundance your skin could turn yellow or orange.

Nature Newssome so-called'non-coding'pieces of RNA may actually encode short proteins that regulate genes,

Protein-coding MESSENGER RNA molecules serve as templates for the production of proteins in cells, while a variety of non-coding RNA molecules are known that do not produce protein

but are known either to regulate gene expression directly or to carry out other functions in the cell.

suggests that more of these mysterious RNA molecules could produce peptides too small to be considered true proteins

In scans of the genome, a DNA sequence is considered generally not potentially protein-coding unless it can encode a string of more than 100 amino acids.

these peptides are chipped usually fragments off larger proteins. Kageyama and his colleagues have now found an RNA that directly codes for four peptides

The team found that the polished rice peptides trigger the truncation of a protein called Shavenbaby,

This shorter form of the Shavenbaby protein activates the expression of genes needed for hair growth.

Sequence analysis suggests that DNA regions capable of encoding tiny peptides exist in front of many protein-coding genes,

which have long been thought to be defunct relics of protein-coding genes. Pseudogenes often contain many signals that would stop protein synthesis and,

as a result, could only encode short amino-acid chains. Maybe this would provide a new way for pseudogenes to have some sort of function

In more relaxed conditions, many animals opt for high-protein foods that help them to grow

Grasshoppers that were exposed to spiders switched from eating protein-rich grasses to munching on several species of sugary goldenrod plants.

or protein-rich'biscuits'and he saw the same trend. Fearful grasshoppers went for the high-sugar cookies rather than the protein-rich bars1.

All that sugary food means that the stressed-out insects are ingesting foods richer in carbon and poorer in nitrogen than their calmer,

protein-pumping cousins. Meanwhile, their bodies are breaking down proteins to make even more glucose. The result is a body that is made of significantly more carbon

and less nitrogen and thus makes poorer fertilizer when it dies and rots. Hawlena thinks that the ecosystem is likely to be changed in two ways by frightened grasshoppers.

But culturing mammalian cells is currently the only way to make some complex protein drugs.

When human proteins such as enzymes are expressed in plant cells, they are decorated usually with plant-specific sugar molecules,

The team tweaked the protein-producing genes, not to alter the sequence of the human protein,

but to ensure that, once made, the proteins would not be moved through the cell's Golgi complex,

a structure where the problematic sugars are added. The engineered maize seeds produced proteins decorated with sugars that could be converted to human forms.

Richard Pattison a cell biologist at the Boyce Thompson Institute for Plant science in Ithaca, New york, calls the approach"very elegant.

Most attempts to solve the sugar problem require mutating the protein, which could disrupt its function,

or engineering plants to modify proteins differently a time-consuming approach that often does not work.

  Other plant systems have been used to make therapeutic proteins. In May, the US Food and Drug Administration approved Elelyso (taliglucerase alfa) a drug for the lysosomal storage disorder Gaucher disease which is produced in cultured carrot cells.

However, making proteins with certain sugar patterns using these systems is still difficult or impossible.

In terms of controlling protein modifications, Kermode s localization technique is"a significant improvement for the production of biopharmaceuticals,

And there particular advantages of packing transgenic proteins into corn kernels. Cereal crops can be grown using established methods,

and seeds are ideal for long-term protein storage. However, Kermode says, the transgenic crops should be grown in contained greenhouses to prevent them from escaping into the environment.

The team also needs to ensure that the seeds produce the protein in higher quantities.

however, maize may one day become the go-to way to make complex protein drugs
