Preferred Label : Fischer–Rosanoff convention;
Detailed label : Fischer–Rosanoff convention (or Rosanoff convention);
IUPAC definition : An arbitrary convention according to which ( )-glyceraldehyde, now known to be ( i
R /i )-2,3-dihydroxypropanal, was named d-glyceraldehyde (with the enantiomer l-glyceraldehyde
and its racemate dl-glyceraldehyde) and taken to have the absolute configuration represented
by the Fischer projection formula shown in the diagram. The atom numbered 1 according
to normal nomenclature rules is conventionally placed at the top of the main chain,
which is drawn vertically and other groups are drawn on either side of that main chain.
The convention is still in use for α-amino acids and for sugars.;
