Product P4510, Poly-ε-Cbz-L-lysine has a Cbz (carbobenzoxy) protecting group on the ε-amino group of each lysine. What are the structures of the α-amino-terminus and the carboxy-terminus, and are the end groups detectable by NMR?
The end groups are free amino (-NH2) and carboxyl (-COOH). Because this a polydisperse material, it would be difficult to detect distinctive end groups via NMR.
