hydroxyproline Amino acid mainly in connective tissue proteins (collagen and elastin); incorporated into the protein as proline and then hydroxylated in a vitamin‐C‐dependent reaction. Peptides of hydroxyproline are excreted in the urine and the output is increased when collagen turnover is high, as in rapid growth or resorption of tissue.
