AIM How are proteins structured?
5
The monomers of proteins are amino acids. Each
amino acid contains

• Draw a triangle around
• the amino group,
• Draw a square around the
• Carboxyl group, and circle
• the R group.

8

together
Amino acids join through dehydration synthesis
(condensation reactions)
