WebAbstract Background: The underlying mechanisms may include altered tissue distribution or increased catabolism via pyridoxal (PL) to pyridoxic acid (PA). Recently, we showed that catabolic enzyme activity could be assessed by substrate product ratios measured in plasma. Objective: WebUrinary excretion of thiamin, riboflavin, vitamin B (6) metabolite 4-pyridoxic acid, nicotinamide metabolites and folate decreased during starvation, but that of vitamin B (12), pantothenic acid and biotin did not. As for blood vitamin levels, only blood vitamin B (1), plasma PLP and plasma folate levels decreased with starvation.

WebPyridoxal 5′-phosphate (PLP), the principal circulating form of vitamin B 6 (B 6 ), is elevated in the plasma of individuals with hypophosphatasia (HPP). HPP is the inborn-error-of-metabolism caused by loss-of-function mutation (s) of ALPL, the gene that encodes the “tissue-nonspecific” isoenzyme of alkaline phosphatase (TNSALP). WebBackground: We quantified pyridoxal 5'-phosphate (PLP), pyridoxal (PL), and 4-pyridoxic acid (PA) in paired serum and cerebrospinal fluid (CSF) samples from children and investigated the effect of age on the concentrations and CSF-to-serum ratios of these vitamers.
