title: [Isomerism of imino acids in collagen peptides].
abstract: Trans/cis ratio of X-Hyp bonds in collagen peptides was determined by chemical shifts of C gamma Hyp in 13C. n. m. r. spectra. 44% of bonds in the cis form was found in human aortic collagen of the patient with idiotia. Probably, it was the result of molecular pathology of collagen during this disease.
