our recent studies have shown that chick embryo epiphyseal cartilage synthesizes three distinct species of proteoglycan ( pg-h , pg-lb , and pg-lt ) which are analogous in having glycosaminoglycan side chains of the chondroitin ( dermatan ) sulfate type but different from one another in regard to the structure of core protein .
