Age- and sex-specific reference intervals and determinants of plasma vitamin B6 metabolites in healthy Chinese adults [PDF]

open access: yesFrontiers in Nutrition
ObjectiveReference intervals (RIs) for vitamin B6 biomarkers remain underexplored in Chinese adults. We aimed to establish age- and sex-specific RIs of pyridoxal 5′-phosphate (PLP), pyridoxal (PL), 4-pyridoxic acid (PA), and their ratios (PLP/PL, PLP/PA,

Prebiotic Synthesis of Aspartate Using Life’s Metabolism as a Guide

open access: yesLife, 2023
A protometabolic approach to the origins of life assumes that the conserved biochemistry of metabolism has direct continuity with prebiotic chemistry. One of the most important amino acids in modern biology is aspartic acid, serving as a nodal metabolite
