macropeptide - ANSWER>more than 100 amino acids
, what is a peptide bond also called - ANSWER>amide bond
what is a peptide bond - ANSWER>bond formed between two molecules when the carboxyl group of one molecule
reacts with the amino group of the other molecule releasing a molecule of water
what type of reaction creates peptide bonds - ANSWER>condensation reaction via loss of water
what is to the left and what is to the right within a peptide - ANSWER>n terminus is to the left (amine) and c
