Dietary S-methylmethionine, a component of foods, has choline-sparing activity in chickens.
Acid hydrolysis of dehulled soybean meal (SBM) and corn gluten meal (CGM) followed by chromatographic amino acid analysis (ninhydrin detection) revealed substantial quantities of S-methylmethionine (SMM) in both ingredients (1.65 g SMM/kg SBM; 0.5 g SMM/kg CGM). Young chicks were used to quantify the methionine- (Met) and choline-sparing bioactivity of crystalline L-SMM, relative to L-Met and c...
متن کاملExcess dietary lysine increases growth of chicks fed niacin-deficient diets, but dietary quinolinic acid has no niacin-sparing activity.
Catabolism of Trp and Lys produces alpha-ketoadipic acid as an intermediary metabolite. An alternate pathway of Trp turnover leads to NAD synthesis. We hypothesized that excess Lys might improve the conversion of Trp to niacin by causing a buildup of alpha-ketoadipic acid, thereby endproduct inhibiting the main Trp catabolic pathway and resulting in more niacin synthesis from Trp. Six bioassays...
متن کاملThe Photoprotective Effect of S-Methylmethionine Sulfonium in Skin
S-Methylmethionine sulfonium (SMMS) was reported to have wound-healing effects; we therefore have investigated the photoprotective effect of SMMS in the present study. SMMS increased the viability of keratinocyte progenitor cells (KPCs) and human dermal fibroblasts (hDFs) following ultraviolet B (UVB) irradiation, and reduced the UVB-induced apoptosis in these cells. SMMS increased the phosphor...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولNeuroprotective Actions of Dietary Choline
Choline is an essential nutrient for humans. It is a precursor of membrane phospholipids (e.g., phosphatidylcholine (PC)), the neurotransmitter acetylcholine, and via betaine, the methyl group donor S-adenosylmethionine. High choline intake during gestation and early postnatal development in rat and mouse models improves cognitive function in adulthood, prevents age-related memory decline, and ...
