WebYou usually use the D- and L- prefixes for Sugars/Carbohydrates and the "R" and "S" prefixes for all other organic compounds. So, I'm pretty sure that "R"-Triose is correct but it is MORE correct to say "D"-Triose. No, (+) and (-) indicate the optical activity where as "D" and "L" indicate the orientation of the chiral center.
