Disulphide bonds, ionic bonds hydrogen bonds, hydrophobic interactions and maintaining the 3D shape of a protein

Resource summary

Bonds In Proteins
1 Hydrogen bonds
1.1 Groups with a slight negative charge will be attracted to those with a slight positive charge
1.1.1 Hydrogen bonds are quite weak, but can be easily broken by changes in the temperature and pH
2 Disulphide bonds
2.1 Disulphide bonds are strong covalent bongs(where electrons are shared between atoms) formed between two cysteine amino acids
2.1.1 Disulphide bonds are very strong, but can be broken by reducing agents
3 Ionic bonds
3.1 Ionic bonds form between molecules that have a full positive or negative charge
3.1.1 Ionic bonds are very strong, but can be broken by changes in pH
4 Hydrophobic interactions
4.1 R-groups that only contain hydrogen or carbon atoms are hydrophobic, and are slightly attracted to each other
4.1.1 These interactions are very weak and are easily broken
5 The 3D shape of a protein is maintained by several types of bond including: hydrogen bonds-involved in all levels of structure,hydrophobic interactions-between non-polar sections of the protein and disulfide bonds- one of the most important type of bond in proteins. occur between two cysteine amino acids.
