Fischer projection of amino acids
http://websites.umich.edu/~chemh215/tutorials/aacids.pdf WebIn chemistry, the Fischer projection, devised by Emil Fischer in 1891, is a two-dimensional representation of a three-dimensional organic molecule by projection. Fischer projections were originally proposed for the depiction of carbohydrates and used by chemists, particularly in organic chemistry and biochemistry.

WebThe notation was extended to -amino acids: L enantiomers are those in which the NH 2 group is on the LHS of the Fischer projection in which the carboxyl group appears at the top. Conversely, the D enantiomers are those in which the NH 2 group is on the RHS. Thus (+)-alanine and (-)-serine are L-amino acids. WebFischer Projections provide aid in visualizing chirality as well as where substituents are oriented within space which is why their application can be useful to many. Chirality from …
