Can someone please explain them?
HO2CCH2CH(CH3)CH2NH2
numbering starts from carboxylic acid group (highest priority)
methyl on C3
amino on C4
naming should have amino first (alphabetical order)
4-amino-3-methylbutanoic acid
identify diamine and diacid
HO2CCH2CH(CH3)CH2COOH and H2NCH2CH(CH3)CH2NH2
the section of polymer is -OCCH2CH(CH3)CH2CONHCH2CH(CH3)CH2NH-
