Solved at last is another great scientific mystery: the structure of the most powerful known chemical-biotin, a rare, growth-promoting vitamin of the B-complex group. Significance: knowledge of its structure may well lead to synthetic manufacture of biotin. So far not more than one-tenth of an ounce of pure biotin has been isolated. Cost: more than...
...complex, for practical purposes, is really a group of eight different chemicals. They are all found in liver and brewer's yeast; some of them also occur in whole grains. Their chemical names: thiamin (B1), riboflavin (B2), pyridoxine (B6), inositol, pantothenic acid, nicotinic acid, biotin and folic acid (first described last week by Dr. Roger John Williams of Texas). To keep up B requirements, Dr. Tom Spies of Birmingham, Ala. suggested a daily sandwich of yeast and peanut butter on peeled wheat bread (made from grain with only the thin outer tissue removed...
...quickly drive the lice away. Dr. Gyorgy hopes the treatment will soon be tried on human beings, for lice carry the germs of typhus. >Dr. Vincent du Vigneaud of Cornell told how three groups of men in three separate laboratories recently turned up one of the original vitamin substances, biotin (recognized 40 years ago). Dr. du Vigneaud, who analyzed its structure, said that biotin is extremely powerful, very difficult to make. Only a few grams have been synthesized-at a cost that would come to $63,800,000 a pound. In an early experiment one and one-half millionth...
