Trans-4-Hydroxy-L-proline by Molecular Depot is a trans-4-hydroxy-L-proline, the modified amino acid that is a constituent of collagen and elastin. Proline residues in collagen are hydroxylated after the chain is made, and the hydroxyl groups stabilise the triple helix, which is why the reaction requires vitamin C and why scurvy weakens connective tissue. It is used as a standard in hydroxyproline assays of collagen content, in connective tissue research and in amino acid analysis. Each unit contains 5 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
