“Amino Acids and Amino Acids derivatives”  

Amino Acids

  In protein science, Amino Acids are organic compounds constructed from only carbon, hydrogen, nitrogen (about 16%), oxygen and sometimes sulfur. All amino acids contain only two groups of molecules: amino (-NH2) and an acid carboxyl (-COOH).
All Amino Acids share this common structure, but differ from each other in that each has a different "side chain", which gives each amino acid a different molecular shape.

Amino Acid Derivatives

  In organic chemistry, an amino acid derivative, as an organonitrogen compound, is any derivative of an amino acid resulting from reaction at an amino group, carboxy group, side-chain functional group, or from the replacement of any hydrogen by a heteroatom.
This definition normally excludes peptides containing amino acid residues.

Amino Acid Structure

The primary structure of a protein is its linear sequence of specific Amino Acids, with the "side chain" portion of each Amino being different for each specific amino acid.

Amino Acid Types

• Encoded Amino Acids
• Amino Acid Essentiality
  • Essential Amino Acids
  • Conditionally Essential Amino Acids
  • Non-Essential Amino Acids
• non-proteinogenic amino acids

  Examples of amino acid derivatives include:

• aminolevulinic acid
