متن کاملPlasma vitamin B6 vitamers before and after oral vitamin B6 treatment: a randomized placebo-controlled study.
BACKGROUND Vitamin B(6) has attracted renewed interest because of its role in homocysteine metabolism and its possible relation to cardiovascular risk. We examined the plasma B(6) vitamers, pyridoxal 5'-phosphate (PLP), pyridoxal (PL), pyridoxine (PN), and 4-pyridoxic acid (4-PA) before and after vitamin B(6) supplementation. METHODS Patients (n = 90; age range, 38-80 years) undergoing corona...
متن کاملHomocysteine, folate, vitamin B6, and cardiovascular disease.
The importance of hyperhomocysteinemia in the pathogenesis of arteriosclerosis was first recognized by study of vascular pathology in children with homocystinuria caused by 2 different enzymatic abnormalities of homocysteine metabolism.1 Homocystinuria caused by deficiency of cystathionine synthase, a pyridoxal phosphate-dependent enzyme, is characterized by vascular abnormalities and frequent ...
