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 .
