l-

 
abbreviation for levo- (left or counterclockwise); a chemical prefix indicating an enantiomer that rotates the plane of polarization of a beam of light in the counterclockwise direction, the other enantiomer being specified as d-. For further explanation, see d-.

l-

 
a chemical prefix that specifies the relative chemical configuration of an enantiomer, carbohydrates corresponding to l-glyceraldehyde and amino acids corresponding to l-serine; see d- for further explanation.

l-

Levorotatory. Compare: d-.
[L. laevus, on the left-hand side]

l-

Prefix indicating a chemical compound to be structurally (sterically) related to l-glyceraldehyde. Compare: d-.

l-

chemical prefix specifiying the relative configuration of an enantiomer, indicating a carbohydrate with the same configuration around a specific carbon atom as l-glyceraldehyde or an amino acid having the same configuration as l-serine. Opposed to d-.

l-

/l- / levo- (left, counterclockwise, levorotatory). Opposed to d-.

L-

In biochemistry, a symbol used as a prefix to indicate the spatial configuration of certain organic compounds with asymmetric carbon atoms. It is used if an organic compound has a configuration about an asymmetric carbon atom analogous to that of L-glyceraldehyde (the arbitrarily chosen standard), in which the hydroxy (OH) functional group is on the left side of the asymmetric carbon atom in a Fischer projection formula: an L-amino acid.

The symbol for levorotatory

l-

1. Abbreviation for levorotatory.
Compare: d
2. Prefix indicating a chemical compound to be structurally (sterically) related to l-glyceraldehyde.
[L. laevus, on the left-hand side]

L-

chemical prefix (written as small capital) that specifies that the substance corresponds in chemical configuration to the standard substance l-glyceraldehyde. Carbohydrates are named by this method to distinguish them by their chemical composition. The opposite prefix is d-.

l-

chemical abbreviation, levo- (i.e. left or counterclockwise).
