Lactic Acid Safety
Lactic Acid formula is CH3CHOHCOOH and it is
known by several other, but not so well known, names...|
2-hydroxypropanoic acid, ethylideneactic acid and 1-hydroxyethanecarboxylic acid.
Lactic Acid is the smallest chemical molecule with an
asymmetric or chiral carbon and exists in two stereo isomer versions... The
L(+) and the D(-) also known as the R(+) and S(-). The L(+) or R(+)
version is one that occurs naturally in animal and human tissues after
There are two 'mirror image' isomers of lactic acid. These both have the same bonding arrangement, but are left and right handed isomers that are mirror images of each other and are called enantiomers.
Using the diagram at right, you can compare the mirror image of (S)-lactic acid to the original (R) form. In other words (S) will not superimpose on (R) but a mirror image of (S) will superimpose on, and is congruent with, the (R) version.
