WebThe D-and L-notation is based on these structures. (Note that D- and L- means something quite different to d- and l-). By definition (R)-(+)-glyceraldehyde is D-glyceraldehyde and (S)-(-)-glyceraldehyde is L-glyceraldehyde. Other carbohydrates are defined as either D- or L- by comparing the stereochemistry at the chirality center next to the -CH 2 OH group (i.e. … WebNow that we're pretty familiar with Fisher projections, it turns out that there's gonna be a new way to determine r and s for them. The reason is because converting these …
