Herein, we propose a very simple and useful method for naming aldoses and ketoses (Fischer projection and cyclic structures) and drawing their structures from their names with the aid of binary and decimal numbers. Fischer projections can be converted simply to the corresponding cyclic and Haworth forms and vice versa. Also one can easily find the R or S descriptors of any chiral center with the aid of a given binary number, without going through with the priority of its attached groups and, draw the enantiomer of any given monosaccharide.
