Study Notes
Protein Characteristics
- Fibrous proteins are insoluble in water and physically tough.
Simple Protein Composition
- Simple proteins are composed of amino acids only.
Levels of Protein Organization
- Primary structure: the sequence of amino acids joined together by peptide bonds.
- Tertiary structure: the 3D shape adopted by the entire peptide chain.
- Secondary structure: the 3D arrangement of localized regions of a protein.
- Quaternary structure: the shape adopted when two or more folded polypeptide chains come together into one complex.
Protein Bonding
- Peptide bonds are formed by joining amino acids in proteins.
Protein Types
- Globular proteins are usually water-soluble and have dynamic functions.
Conjugated Proteins
- A non-protein component is attached to a simple protein in conjugated proteins.
Derived Proteins
- Derived proteins are formed from proteins through chemical or enzyme-catalyzed modifications.
