Protein structure
Amino acid bonds formed along the molecule are what hold the shape of the protein together. These bonds may only be formed if the correct amino acid is present. If it’s not present, the bond cannot form and the correct shape cannot be taken. Because protein function is dependent on the protein’s shape, faulty amino acid presence will result in the protein being unable to carry out its correct function.
Levels of Protein Structure:
Levels of Protein Structure:
- Primary: Basic sequence of amino acids (covalent bonding)
- Secondary: Polypeptide coils into alpha helix and beta pleated sheets (hydrogen bonding)
- Tertiary: Irregular bonds are formed between amino acid side chains construct a single polypeptide (covalent bonds, Van Der Wals bonds, ionic bonds , hydrophobic/ hydrophilic interactions)
- Quaternary: Multiple polypeptides join together to make a larger, more complex molecule (covalent bonds, Van Der Wals bonds, ionic bonds , hydrophobic/ hydrophilic interactions)
