A system is presented for designating, with symbols, all chair and boat conformations of all pyranoid sugars and derivatives. For chairs, these symbols are CA and CE: for boats: B1A, B1E, B2A, B2E, B3A, and B2E. Symbols A and E describe an axial or equatorial "glycosidic" group of the α-anomers (D and L series).
