Glycine is the simplest amino acid. It's sidechain (sometimes called the R-group) is one hydrogen atom. Because it has a hydrogen atom as its sidechain, glycine is the only achiral amino acid. Because it lacks a bulky sidechain, glycine has a high degree of rotational freedom and is frequently found in turns along with proline.
Representations
- The representation of glycine shows atoms and covalent bonds, but does not show the true size and shape of the molecule.
- The representation shows size (atoms at their van der Waals radii) and shape but hides structure behind the surface.
- The representation shows only bonds, and is better for seeing through layers of a large molecule.
- In this view, the atoms that would, in a polypeptide chain, become part of the are highlighted.
