Potent Radical-Scavenging Activities of Thiamin and Thiamin Diphosphate
Various radical-scavenging activities of thiamin and thiamin diphosphate (TDP) were found in some in vitro experiments. Thiamin and TDP caused considerable suppressive effects on superoxide generation in hypoxanthine and xanthine oxidase system which was measured by a sensitive chemiluminescence method using 2-methyl-6-[p-methylphenyl]-3,7-dihydroimidazo[1,2-alpha]pyrazin-3-one (MCLA), and thei...
متن کاملAvian Thiamin Deficiency
A correlation of the histopathology and clinical behavior of thiamin deficient pigeons has been undertaken. Opisthotonus in acutely deficient pigeons was frequently attended by no degenerating nerve fibers or neurons in either the central or peripheral nervous systems. When the deficiency was complicated by starvation, it developed more slowly, opisthotonus appeared later, and many degenerating...
متن کاملA new thiamin salvage pathway.
The physiological function for thiaminase II, a thiamin-degrading enzyme, has eluded investigators for more than 50 years. Here, we demonstrate that this enzyme is involved in the regeneration of the thiamin pyrimidine rather than in thiamin degradation, and we identify a new pathway involved in the salvage of base-degraded forms of thiamin. This pathway is widely distributed among bacteria, ar...
متن کاملThiamin triphosphatase and conducting sites.
I. Is the monomolecular model as proposed by the electrophysiologists still adequate? Thus Hodgkin and Huxley [1, 2] were able to show that the sodium conductance of the membrane (gNa) rapidly raised and then falls down within msecs to the resting value, while de potassium conductance (gK) increases to a steady value stable as long as E m is kept constant. Hodgkin and Huxley have proposed empir...
