This fantastic vitamin was isolated in 1936 by Professor Fritz Kögl of Utrecht, Holland but Biochemist Vincent Du Vigneaud of Cornell and his colleagues identified it as an animal vitamin in 1940. The possible molecular patterns ran into millions. Last January, Dr. Du Vigneaud and colleagues were able to announce that the possible molecular patterns had been reduced to five; then when the position of the nitrogen atoms was ascertained, these were...
...Caltech biochemists believe that their discovery is further proof that immunization, whose physiological mechanics has long been a major mystery, is a molecular phenomenon. In the blood stream of animals are large protein molecules called serum globulin. If a bacterium, virus, poison molecule or other "antigen" is near the point where these molecules are formed, the adaptable globulin molecules change their shape and assume structures complementary to those of the invading antigens, so that they can combine with them and neutralize them. After the infection or poisoning has been overcome, these changed globulin molecules remain in the blood as antibodies...
Died. Jean Perrin. 71, refugee French physicist, 1926 winner of the Nobel Prize; in Manhattan. A onetime associate of the Curies, famed for his studies of molecular physics, he announced in 1938 that he had discovered evidence of the existence of an element heavier than element 92 (uranium), called it transuranium...
...Caltech biochemists think their discovery proves that immunization is a molecular phenomenon. In the blood stream of animals are large protein molecules called serum blobulin. If a bacterium, virus, venom molecule or other "antigen" is near the point where these molecules are formed, the adaptable molecules change their shape and assume structures complementary to those of the antigen, so that they can combine with them and neutralize them. After the infection has been overcome, these changed protein molecules remain in the blood as antibodies, ready to attack any reappearing enemies. Hence immunity...
...precisely determined its structure-what atoms in what pattern form its molecule. But when the theory is cleared up, useful applications will follow thick & fast. Reason: chemists will know what they are working with and can abandon the essentially trial-&-error methods now forced upon them. Chief center of molecular lignin research is the U.S. Forest Products Laboratory at Madison...
