...they manufacture, they use protein molecules called enzymes as their machine tools. Scientists probing the secrets of life have learned that enzymes are long chains of amino acids linked together in definite order and tightly coiled or folded. But no one is sure just how they work. Last week Biochemist Klaus Hofmann of the University of Pittsburgh offered a glimmer of understanding by announcing the first partial synthesis of a working enzyme...
...years. Biochemist Choh Hao Li has devoted himself to discovering the functions of a small part of a small, lima-bean-sized gland that is lodged at the base of the human brain. With each experiment the Canton-born professor of biochemistry and endocrinology has come closer than any man before him to explaining how the front half of the human pituitary, the body's master gland, controls so many functions through the hormones it manufactures. Because his success represents a singular medical triumph, Dr. Li last week was awarded the $10,000 Albert Lasker Basic Research Award...
Duplicating Nature. From the pitui-tary's front lobe. Biochemist Li has isolated no fewer than five other hormones, including the enormously potent adrenocorticotropic hormone (ACTH). Three other hormones he discovered are involved in the female reproductive cycle; finally there is the human growth hormone (HGH, or somatotropin), which may yet prove to be the most important...
...chemists synthesize life? Not quite yet. But famed Biochemist Gerhard Schramm of the Max Planck Institute for Virus Research at Tubingen, Germany, is coming remarkably close. Last month he told a conference at Munich that he has managed with simple chemicals to build nucleic acid, the most vital compound in living organisms-and he used the same processes that are thought to have created the first life on earth...
Died. Dr. Conrad Arnold Elvehjem, 61, president for six years of the University of Wisconsin and biochemist whose identification of nicotinic acid as a new vitamin (now called niacin) led directly to the cure of pellagra, and who won medicine's Lasker Award in 1952; of a heart attack; in Madison...
