1. In view of the suggested association between collagen and acid mucopolysaccharides in the connective tissues, this study was designed to see whether the lathyrus factor, beta-aminopropionitrile, affected the acid mucopolysaccharides as well as inhibiting the normal polymerization of collagen. The changing pattern of these two components of cartilage from normal and lathyritic chick embryos aged 14-20 days is described. The chondroitin sulphates and their protein complexes have been isolated from these cartilages, characterized and compared, particularly with respect to their sulphate content; no significant differences in quality or quantity were detectable. 2. Saline extracts of normal and lathyritic cartilages were also compared; whereas the collagen content of lathyritic extracts was increased to ten times that in the normal, the acid mucopolysaccharide content of both extracts was always the same. 3. It therefore appears that in the chick embryo beta-aminopropionitrile does not affect the acid mucopolysaccharides of the developing cartilage.
