Study Notes
Proteins and Amino Acids
- Amino acids are the building units of proteins.
- There are 20 amino acids that occur in the human body.
- Amino acids differ from each other by their R-groups.
- Amino acids are chemically classified based on the properties of their R-groups.
- Glycine is the only amino acid that is not of the L-α amino acid except category.
- Amino acids are organic acids that contain a hydrogen atom, a carboxyl group, an amino group, and a side-chain (R group), all attached to the α-carbon.
- Non-polar amino acids have side chains that contain hydrocarbon or alkyl side chains.
- Methionine has a side chain with a sulphur group that ends with CH3.
- Hydrophilic amino acids prefer to function in an aqueous environment.
- Ketogenic amino acids give rise to acetate or acetoacetate on catabolism.
- A negative nitrogen balance occurs when nitrogen loss exceeds incorporation.
- Essential amino acids must be supplied in the diet because they cannot be synthesized in the human body.
- Hydrophobic amino acids have side chains that are in the interior of the protein molecule.
