Study Notes
Protein Classification
- Proteins can be classified based on their shape or composition.
Protein Types
- Fibrous proteins: example is collagen.
- Globular proteins: example is hemoglobin.
- Insoluble proteins in water: fibrous proteins.
- Proteins composed of only amino acids: simple proteins.
Protein Structure
- Primary structure: refers to the linear sequence of amino acids.
- Secondary structure: often depicted schematically as a piece of curled ribbon, formed by hydrogen bonds between distant carboxyl and amino groups (alpha helix or beta pleated sheet).
- Tertiary and quaternary structures: formed by interactions between side chains (hydrophobic, ionic, and disulfide bonds).
- Quaternary structure: term for a protein composed of many subunits.
Conjugated Proteins
- Example: hemoglobin (a protein with a non-protein component, heme).
Protein Bonds
- Disulfide bonds: hold proteins together, example is insulin.
Protein Subunits
- Oligomer: term for a protein composed of two or more subunits (monomers).
- Dimer: term for a protein composed of two subunits.
Non-Protein Structure Level
- Evolutionary relationships: NOT a level of protein structure.
