Abstract:
1. Soluble Type I collagens were isolated from the scale and bone (skull) of lathyritic carp. Each tissue collagen was assumed to consist of two different molecular forms, (alpha 1)2 alpha 2 as a main component and alpha 1 alpha 2 alpha 3 as a minor one. 2. The possible coexistence of these two forms in soluble Type I collagen of carp was previously observed for skin and muscle, but not for the swim bladder in which only the form of (alpha 1)2 alpha 2 was found. 3. These composite results suggest the wide distribution of alpha 1 alpha 2 alpha 3 heterotrimers in collagenous tissues of carp.
