Study Notes
Protein Classification
- Complete proteins (animal): Contain amino acids in proportionate amounts.
- Incomplete proteins (vegetable): Contain fewer amino acids.
- Classification by chemical structure:
- Simple proteins (holoproteins): Formed from amino acids only.
- Conjugated proteins (heteroproteins): Formed from amino acids and other substances.
Protein Function
- Structural: Form important structures like intermediate filaments.
- Immunological: Provide antibody defense.
- Enzymatic: Carry out biological activities.
- Homeostatic: Maintain cellular balance.
- Contractile: Cause muscle contraction.
- Hormonal: Examples include insulin.
Additional Proteins
- Collagen: Prevents wrinkles.
