Chondroitin sulfate (CS), a well known nutraceutical, and keratan sulfate (KS) are glycosaminoglycans involved in the structure of cartilage proteoglycan, aggrecan. Since CS is extracted from cartilage, there may be a possibility that purified CS is contaminated with small amount of KS. A total of 15 samples, including four samples of CS as laboratory reagents, one sample of CS as a food additive...
Keratan sulfate is a glycosaminoglycan found in the structure of cartilage proteoglycans, aggrecan and fibromodulin. This study was undertaken to detect this glycosaminoglycan in meat products containing mechanically separated chicken meat (MSCM) having cartilage particles. Dry-defatted samples of MSCM and meat products with or without MSCM were digested with papain, and a non-dialyzable fraction...
