Q

Structure of amino acids

A
  • Carboxyl group (-COOH-)
  • Amino group (- NHH-)
    These 2 groups always joined together by a central carbon
  • R group (Depends which amino acid it is)
17
Q

Amino acid condensation polymerisation

A

Allow adjacent amino acids to join together by remocing the OH from COOH and H from NHH
- Forming water as a byproduct
