Abstract
The mnemonic SOS (Same, Opposite, Same) can be helpful to recall the stereochemistry in either D-glucose or L-glucose. It refers to the configurations of C-2, C-3, and C-4 relative to that of C-5 in an aldohexose. Same and Opposite refer to either the R or S configuration or to the relative positions of the OH groups on the Fischer projection structural formula. The SOS mnemonic can help to reinforce that gluco specifies the relative configurations of stereocenters in the molecule.

Chad E. StephensJournal of Chemical Education2010 87 (11), 1186-1187The familiar word OREO (as in the cookie) is presented as a simple mnemonic for remembering the basic steps of the classical tautomerization mechanisms in organic chemistry. For acid-catalyzed tautomerizations, OREO stands for proton on, resonance, proton ...
