The portion of non-spiralized peptide chain in collagen 1 molecules from the skin of cold-blooded animals, such as Arenicola marina, Gadus morhua marisalbi, Eleginus navaga, Rana amurensis, Rana temporaria, Rana semiplicata, Rana ridibunda, Rana dolmatina, Rana graeca, Bombina variegata was determined by recombination-kinetic method. It has been shown that the portion of non-spirilized part of collagen I molecule changes in the animals studied from 2 to 11% and correlates with the temperature of their habitat. There exist also substantial interspecies differences in the collagen I molecule structure.
