Amino Acids and the Peptide Bond
Captions available
The idea
An amino acid is a protein's monomer; a peptide bond is the covalent bond formed by dehydration synthesis between two amino acids.
In practice
Twenty amino acids, each with a different side chain, combine in varying sequences to build every protein.
Where people slip
A peptide bond links two amino acids at a time; a protein forms by adding one after another to a growing chain.
