Metabolite Identification
Common NameProline betaine
DescriptionProline betaine is an osmoprotective compound found in urine. It is thought to serve an osmoprotective role for the kidney. Proline betaine is a glycine betaine analogue found in many citrus foods. Elevated levels of proline betaine in human urine are found after the consumption of citrus fruits and juices (PMID: 18060588 ). Proline betaine is a biomarker for the consumption of citrus fruits.
