Preferred Label : l, u;
IUPAC definition : Stereodescriptors of diastereoisomers with two chirality elements. When the two chirality
elements are both i R /i or both i S /i the molecular entity is described as having
an i l /i relationship ( i l /i like), when one chirality elements is i R /i
and the other i S /i the molecular entity is described as having a i u /i relationship
( i u /i unlike). The notation can be extended to molecules with more than two
chirality elements whereby the i l /i , i u /i relationships of the chiral elements
are considered in pairs.;
