The notations D and L are used to describe configurations of carbohydrates and amino acids. Glyceraldehyde has been chosen as arbitrary standard for the D and L notation in sugar chemistry. ...dextrorotatory (right handed rotation) vs Laevorortatry (left hand rotation). The D,L convention, not to be confused with the d and l descriptors used to designate the direction of specific rotation of chiral compounds, is a convention used to distinguish between enantiomers of chiral monosaccharides and chiral alpha-amino acids.
