Vital Micronutrients In Depth Linus Pauling Institute
Q. Your early research concerned the effects of toxins on mitochondria, the organelles within cells that produce energy. How do mitochondria respond to toxins? A. During my Ph.D. work in Switzerland, I used various toxins that generate oxidative stress, including a lipid hydroperoxide or oxidized lipid called tert-butylhydroperoxide and other toxins like menadione or alloxan, which undergo redo...
متن کاملExtroverted confusion--Linus Pauling, Melvin Calvin, and porphyrin isomers.
No other modern era chemist has influenced chemistry and molecular biology as much as Professor Linus Pauling (1901–1994) (Fig. 1). In a career spanning seven decades he worked and made important contributions in all areas of chemistry including physical, structural, analytical, inorganic, and organic chemistry, as well as biochemistry. While always being interested in the structure and bonding...
متن کاملVitamin C supplementation and the common cold--was Linus Pauling right or wrong?
In 1970 Linus Pauling claimed that vitamin C prevents and alleviates the episodes of the common cold. Pauling was correct in concluding from trials published up till then, that in general vitamin C does have biological effects on the common cold, but he was rather over-optimistic as regards the size of benefit. His quantitative conclusions were based on a single placebo-controlled trial on scho...
متن کاملChemistry: Pa Uling and Corey the Structure of Synthetic Polypeptides by Linus Pauling
In a preliminary communication last year' we stated that there are only two helical configurations of polypeptide chains in which the residues are all equivalent and intramolecular hydrogen bonds are formed, and in which the interatomic distances, bond angles, and other structural features, especially the coplanarity of the conjugated amide system, are as required by earlier work in these Labor...
متن کاملThe Dissociation Energy of Carbon Monoxide and the Heat of Sublimation of Graphite by Linus Pauling
Metasequoia has long been a member of the forest of the temperate zone, and has commonly ranged southward into latitudinal ecotones with the forests of the subtropical zone. During the Eocene epoch this conifer extended still farther south in the uplands, where it lived in an altitudinal ecotone bordering the Clarno flora of the John Day Basin. It has survived in the high valleys of central Chi...
