D-,L- Designation given to carbhydrates, amino
acids, lipids and those compounds whose
stereochemistry is derived from
carbohydrates and amino acids,
accdording to the corresponding
conventions.
D(+)- Specifically indicates the direction of
optical rotation in addition to the
D-(or L-) affix, hence providing a more
accurate charaterization.
DL-
Denotes the racemate of a compound
whose enantiomers have the designation
D- or L-.
(+)-,( - )- Some natural products have adopted this
designation (e.g. camphor); the
systematic
nomenclature of the synonym is in
accordance to the sequence rule.
