Web1900 Fischer develops the first systematic method for depicting stereochemistry (Fischer projections) and a notation for designating configuration (D/L notation). 1905 Rosanoff arbitrarily assigns the configuration of the structure corresponding to (+)-glyceraldehyde as being D-glyceraldehyde. WebFischer projection. In the Fischer projection all of the vertical lines go back into the paper and the horizontal bonds come out toward you. You have to remember this method because the structure looks flat. Also the only kind of change you can do to the structure is a rotation of 180o. All of these methods for writing stereochemical structures are

"Chiral molecules can be described as ones with a set of stereoisomers or left and right-handed enantiomers. As defined by Lord Kelvin, a molecule has chirality “if its image in a plane mirror, ideally realized, cannot be brought to coincide with itself.” In other words, a chiral molecule is asymmetrical in the sense that it's mirror image will not be an exact copy of itself. Chirality is key to understand in many fields such as drug development as one enantiomer of a drug may caus… " - Fischer projection stereochemistry
