The naturally occurring α-tocopherol stereoisomer RRR-α-tocopherol is predominant in the human infant brain.
α-Tocopherol is the principal source of vitamin E, an essential nutrient that plays a crucial role in maintaining healthy brain function. Infant formula is routinely supplemented with synthetic α-tocopherol, a racaemic mixture of eight stereoisomers with less bioactivity than the natural stereoisomer RRR-α-tocopherol. α-Tocopherol stereoisomer profiles have not been previously reported in the h...
متن کاملDegradation of phospholipid in Pseudomonas aeruginosa induced by polymyxin B.
Effects of polymyxin B on the synthesis and degradation of lipid, ribonucleic acid (RNA) and protein in Pseudomonas aeruginosa were investigated. It was found that polymyxin B caused a marked degradation of the lipid fraction which was prelabeled with (3H-2)-glycerol. Thin-layer chromatographic analysis indicated that the main degraded lipids were phosphatidylethanolamine and phosphatidylglycer...
متن کاملAntioxidant effect of 4-nerolidylcatechol and α-tocopherol in erythrocyte ghost membranes and phospholipid bilayers
4-Nerolidylcatechol (4-NC) is found in Pothomorphe umbellata root extracts and is reported to have a topical protective effect against UVB radiation-induced skin damage, toxicity in melanoma cell lines, and antimalarial activity. We report a comparative study of the antioxidant activity of 4-NC and α-tocopherol against lipid peroxidation initiated by two free radical-generating systems: 2,2'-az...
متن کاملγ-Tocopherol, but not α-tocopherol, potently inhibits neointimal formation induced by vascular injury in insulin resistant rats
Insulin resistance may enhance the neointima formation via increased oxidative stress. However, clinical trials investigating the benefit of antioxidant therapy with α-tocopherol showed negative results. Recent studies showed that chemical characteristics of γ-tocopherol are distinct from those of α-tocopherol. We hypothesized that γ-tocopherol is superior to α-tocopherol in preventing the neoi...
متن کاملProbucol-Induced α-Tocopherol Deficiency Protects Mice against Malaria Infection
The emergence of malaria pathogens having resistance against antimalarials implies the necessity for the development of new drugs. Recently, we have demonstrated a resistance against malaria infection of α-tocopherol transfer protein knockout mice showing undetectable plasma levels of α-tocopherol, a lipid-soluble antioxidant. However, dietary restriction induced α-tocopherol deficiency is diff...
