ACTH, expensively extracted from the pituitary glands of cattle, also helps many a disease, such as arthritis, but the magic compound, unfortunately, is anything but simple. It is a polypeptide, a large molecule (molecular weight 4,500) made up of many amino-acid units arranged in a long chain. Chemists have puzzled over its structure for years, but have learned only bits and scraps about it. Polypeptides (related to proteins) are baffling things to deal with...
Citation: "Examining red bread mold, in collaboration with Dr. E. L. Tatum, he discovered that the genes control the synthesis of vitamins and amino acids in the living cell, and thus he made possible further discoveries not only of the nature of the genes but of principles in biochemistry and bacteriology...
...Nobel Prize for discovering the positron. Meanwhile, Caltech biologists have been probing their own areas of the invisible. Geneticist Alfred H. Sturtevant described the linear order of genes; Calvin B. Bridges provided proof for the chromosome theory of heredity. In determining that genes control the synthesis of vitamins and amino acids, George Beadle discovered the bread mold, Neurospora, as an effective research tool. This has sped the progress of genetics a hundredfold, was partly responsible for the successful increased production of penicillin...
...favorite beverage is a "food" and full of health-giving nutrients found academically respectable confirmation in a book by German Physiologist Wilhelm Stepp. A quart of beer from his area, said Dr. Stepp, contains at least a man's daily requirements of several B vitamins, plus phosphorus and amino acids. Dr. Stepp practices in Munich...
...down water retention in heart cases) less wearisome and more nourishing. The trouble has been that because it lacks protein the rice-fruit menu causes the dieter to burn up his own body proteins. Metabolism experts have tried to prevent this in Brantner's case by adding two amino acids, lysine and threonine, to his diet. Also, he has had a break because his rice dishes prepared in the center's elaborate metabolic kitchens have included such delicacies as olives, mushrooms and an apple pie (made with a rice crust...
