Abstract
In skate (Raja erinacea Mitchell, 1825) egg capsule, variations in amino acid composition, notably glycine and hydroxyproline, were found to be related to morphologically distinct sites. Components sharing elution characteristics with cross-linking amino acids in collagen and elastin were detected and the relative amounts of these peaks also displayed regional variation. If the skate egg capsule contains collagen, these results suggest it is associated with differing amounts of other protein(s). The varying relative proportions of collagen and non-collagenous protein is predicted to contribute to site-specific differences in physico-chemical properties of the egg capsules.
