  5. 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.

Microspheres were formed from blends of the biodegradable polymer poly(DL-lactic-co-glycolic acid) (PLGA) together with poly(epsilon-CBZ-L-lysine) (PCBZL) by a double-emulsification/solvent evaporation technique. The size of the microspheres formed by this method was dependent both on the total concentration of the polymers
