About 10% of the urinary hydroxylysine is linked to peptides. There is no significant difference between the excretion of peptide-bound hydroxylysine and hydroxylysine measured in the non-dialysable fraction of the urine. Non-dialysable hydroxylysine is highly glycosylated and contains mainly glucosyl-galactosyl-hydroxylysine. It is concluded that the urinary peptide-bound hydroxylysine is present in the non-dialysable collagen polypeptides. Their unusual carbohydrate composition is discussed.
约10%的尿羟赖氨酸与肽相连。结合肽的羟赖氨酸排泄量与尿中不可透析部分测得的羟赖氨酸排泄量之间无显著差异。不可透析的羟赖氨酸高度糖基化，主要含有葡萄糖基-半乳糖基-羟赖氨酸。得出的结论是，尿中结合肽的羟赖氨酸存在于不可透析的胶原蛋白多肽中。并讨论了它们不同寻常的碳水化合物组成。
