WebDOI: 10.1002/ejoc.201600890. I came across this graphical abstract with M and P overlayed. After reading the article it became clear that M and P were being used as stereochemical descriptors, presumably of some kind of axial chirality/screw sense. When I've previously looked, I've often seen either (+)/ (-) (where + is the right-handed screw ... WebAll three also use single bonds to indicate stereochemistry, with the projection itself implying the stereochemical configuration, rather than hash and wedge bonds. ChemDraw interprets the stereochemistry according to the established conventions of each projection. Below are the same three molecules with chiral centers identified.

Many biologically active molecules are chiral, including the naturally occurring amino acids (the building blocks of proteins) and sugars. The origin of this homochirality in biology is the subject of much debate. Most scientists believe that Earth life's "choice" of chirality was purely random, and that if … See more In chemistry, a molecule or ion is called chiral if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes.
