Answer #1

Amino acid monomers are joined together by peptide bonds. In this process, the c' terminus of first amino acid is covalently joined to the N' terminus of the second one. Bond formation is shown below:Peptide bond formation. N R - - 0 -C - 1C N-C - TH он I- Carboxyl group amino group olHR - I U - G-C-N- ċ-c 2 - pH I I
