i believe i know the first one correct me if im wrong. but for the second two i have no idea where im looking at for them. please help me, i just attached the first one because you need that for the other two

13, the nitrogen atoms have been numbered from 1 to 3 . Where are the peptide bonds? Only between CB and N3 Detween N1 and CS, and between N3 and CP Between N2 and C ? Between CS and C6, and between CY and C10 Between C6 and N2, and between CB and N3. In the peptide shown in question 5 , the N terminus is located at: This particular peptide does not have an N-terminus N3 N1. N2 N1 and N3 In the peptide shown in question 5 , the C terminus is located at: C12 C1 C1, C2, and C10 C2 C10 C3
