title: The metabolism of galactose in the human gastric mucous membrane.
abstract: After incubating pieces of human gastric mucous membrane with radioactive galactose, labeled metabolites of glycolysis (FDP,PEP,pyruvate):hexose and hexosamine intermediates in glycoconjugate biosynthesis (gal-1P, UDP-gal,acetylated hexosamines, and their phosphate esters), amino acids (glycine, alanine, and serine), and oxoglutarate as a metabolite of the citric acid cycle were isolated from the acid-soluble fraction. These results suggest that galactose in the human gastric mucous membrane is epimerized to glucose and metabolized in the glycolytic pathway together with oxidation in the citric acid cycle and in the direction of glycoconjugate biosynthesis.
