...human body, they play a vital role in helping regulate the chemical reactions that protect cells and convert food into energy and living tissue. Some vitamins are produced within the body. Vitamin D, for example, is manufactured in the skin during exposure to sunlight, and three other vitamins (K, biotin and pantothenic acid) are made inside the human gut by resident bacteria. But most vitamins must be ingested...
Last week there was also encouraging news about helping babies with genetic disorders-while they are still in the womb. The success, described by doctors at the University of California in San Francisco, was in a tiny patient with a rare inherited disease called biotin dependency. Biotin, a B vitamin, is necessary for certain metabolic processes. In people with the disease, the body's use of biotin is somehow disrupted. Symptoms include hair loss, lethargy, coma and susceptibility to infection. The only treatment is daily doses of the vitamin...
...irradiated foods are not at all radioactive, and no poisonous materials have been found in them. Suspicion is that the radiation may completely destroy natural vitamins (biotin, riboflavin. etc.), since the test animals show classic symptoms of severe vitamin deficiency. But the tests were haphazard and incomplete, so no one is sure that this is really the reason or how irradiated foods can be made assuredly safe. Director Morse has concluded that the whole program had better be restudied...
...also grows nonsexually, so a truckload of mold with the same heredity can be grown, if desirable, from a single spore. But the best thing about Neurospora is that it asks for so little. It thrives on a medium containing nothing but mineral salts, sugar and a single vitamin, biotin. Everything else that it needs it can make out of these simple foods...

Royal jelly is exceptionally rich in pantothenic acid (a B vitamin believed to prevent grey hair), and in pyridoxin and biotin (also B vitamins). Dr. Gardner mixed up a brew of these three ingredients and a substance known as sodium yeast nucleate, and fed it to some fruit flies. The exciting result: the Gardner mixture increased the fruit flies' average life span 46%; pantothenic acid alone increased...
