Sentences with phrase «reactive oxidant»

Symposia and poster abstracts will focus on reactive oxidant stress, nitric oxide, angiotensin II, angiotensin (1 - 7), glutamate, GABA and the transcriptional and translational regulation of the receptors for many of these mediators.

More than one hundred vitamin B6 - dependent enzymes have been identified, mostly involved in amino acid metabolism: for oxygen transport via hemoglobin synthesis; in blood sugar regulation via conversion of stored carbohydrate to energy; in the development of the myelin sheath surrounding nerve cells; in the conversion of alphalinoleic acid to the essential long - chain fatty acid DHA; 28 and in the synthesis of neurotransmitters, phospholipids and sphingolipids, the vitamin niacin from tryptophan, and other vital metabolites.5 In addition to its role in enzyme reactions, B6 appears to moderate the action of some steroid hormones such as the glucocorticoid hormones, which in turn influence the metabolism of protein, carbohydrate and lipids.5, 9 B6 also is a potent antioxidant, rivaling carotenoids and vitamin E in its ability to quench reactive oxidants in the body.29
