What protein derived from the shellfish shell is noted as potentially appearing in non-food supplements like glucosamine?
Answer
Chitin
Chitin is the structural protein derived from the hard shell of shellfish, and its presence extends beyond food items. It is specifically mentioned that individuals must check the source of non-food items such as glucosamine supplements, which are often used for arthritis management, as these can be derived from oyster shells containing chitin. Furthermore, certain calcium supplements may also source their calcium from oyster shells. Awareness of chitin in these non-food contexts is necessary for individuals who must maintain strict avoidance protocols for shellfish components.
