5 Differences between Proteinogenic Amino Acid and Non-proteinogenic amino acids

Proteinogenic vs Non-proteinogenic amino acids
Proteins are nitrogen containing bio molecules made up of amino acids joined by peptide bond.
An amino acids consists of a central α carbon atom joined by 4 groups namely Hydrogen (H), amino group (–NH2), carboxyl group (-COOH) and side group (R-group).
Proteinogenic amino acids are “protein forming amino acids where as non-proteinogenic amino acids not naturally incorporated into proteins
 Proteinogenic Amino Acid vs Non-proteinogenic amino acids
Proteinogenic amino acids
Non-proteinogenic aminoacids
Proteinogenic amino acids are those which are naturally encoded in the genetic code of any organism
Non-coded or non-proteinogenic amino acids are those not naturally encoded or found in the genetic code of any organism.
Natural amino acids incorporated into proteins during translation
Amino acids not incorporated into proteins during translation
Protein forming amino acids or amino acids that are natural constituents of proteins
Not Protein forming amino acids or amino acids that are not naturally incorporated into proteins
Coded amino acids or proteinogenic amino acids are those which are naturally encoded in the genetic code of any organism
Non-coded or non-proteinogenic amino acids are those not naturally encoded or found in the genetic code of any organism.
Examples: In Eukaryotes all 21 amino
acids including selenocysteine are  proteinogenic. (Glycine, alanine, valine etc)
Ornithine, citruline, Gamma-Aminobutyric Acid (GABA) etc
Forms all proteins that carry out different activities of the cell like enzymes, hormones like insulin.
They are often intermediates in biosynthesis with specific physiological functions.
For example GABA is a neurotransmitter that blocks impulses between nerve cells in the brain.
