1

monomers of polypeptides
2
Q
What is the general structure of an amino acid?
A
- Amine (NH2 group)
- Carboxylic acid group (COOH)
- H atom
- R group (a chain that causes amino acids to differ in function and properties)
3
Q
How are amino acids linked to form a protein (polypeptide)?
A
- Peptide bonds (covalent)
- Hydroxyl (OH) from COOH is removed from one amino acid
- Hydrogen (H) atom is lost from the amine group of an amino acid

Q
How are peptide bonds formed?
A
Through condensation reactions where water is relased
