Fischer projection formulas are often used to depict compounds such as glyceraldehyde, lactic acid, and tartaric acid. Draw Fischer projections for both enantiomers of
(a) Glyceraldehyde,
(b) Tartaric acid
(c) Lactic acid, and specify the (R) or (S) configuration at each chirality center. [in Fischer projection formulas the terminal carbon that is most highly oxidized is placed at the top of the formula (an aldehyde or carboxylic acid group in the specific examples here).]
