Accumulation and degradation of thiamin-binding protein and level of thiamin in wheat seeds during seed maturation and germination.
Changes in the levels of thiamin-binding globulin and thiamin in wheat seeds during maturation and germination were studied. The thiamin-binding activity of the seed proteins increased with seed development after flowering. The thiamin content of the seeds also increased with development. Thiamin-binding activity decreased during seed germination. On the other hand, immunological analysis using...
متن کاملPotent 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 کاملDetermination of thiamin and thiamin phosphate esters in blood by liquid chromatography with post-column derivatization.
We demonstrate a liquid-chromatographic method involving post-column derivatization for determining the concentration of thiamin and its phosphate esters in human blood. Blood, erythrocytes, or plasma is deproteinized and centrifuged. Aliquots of the samples are applied to a mu Bondapak C18 column attached to a "high-performance" liquid chromatograph. Addition of potassium ferricyanide/sodium h...
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...
