title: Histidinoalanine in human urine.
abstract: Histidinoalanine, a cross-linking component of connective tissue proteins, was detected in the acid hydrolysate of human urine. The concentrations in urines from newborn babies, children, and adults were 1.33 +/- 0.27, 0.77 +/- 0.23, and 0.89 +/- 0.33 nmol/mg creatinine, respectively. Possible origins of urinary histidinoalanine are discussed.
