An example of an amino acid sequence plotted on a helical wheel. Aliphatic residues are shown as blue squares, polar or negatively charged residues as red diamonds, and positively charged residues as black octagons. A helical wheel is a type of plot or visual representation used to illustrate the properties of alpha helices in proteins.

The alpha helix is also commonly called a: Pauling–Corey–Branson α-helix (from the names of three scientists who described its structure); 3.6 13-helix because there are 3.6 amino acids in one ring, with 13 atoms being involved in the ring formed by the hydrogen bond (starting with amidic hydrogen and ending with carbonyl oxygen)
English: Amino acid catabolism. This is a modified version of a diagram created July 2011 by Mikael Häggström and based on information in Lippincott's Illustrated Reviews: Biochemistry [1]. The Lippincott's text and the original diagram contained several discrepancies when compared with 5 other prominent biochemistry textbooks.
Codon–amino acids mappings may be the biological information system at the primordial origin of life on Earth. [122] While amino acids and consequently simple peptides must have formed under different experimentally probed geochemical scenarios, the transition from an abiotic world to the first life forms is to a large extent still unresolved ...
