racemization

   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia 0.01 sec.
racemization /ra·ce·mi·za·tion/ (ra″sĕ-mĭ-za´shun) the transformation of one half of the molecules of an optically active compound into molecules having exactly the opposite configuration, with complete loss of rotatory power because of the statistical balance between the equal numbers of dextro- and levorotatory molecules.
ra·ce·mi·za·tion (rs-m-zshn, rs-)
n.
Conversion of an optically active substance to a raceme.

racemization [ra″sĕ-mĭ-za´shun]
the transformation of one-half of the molecules of an optically active compound into molecules that possess exactly the opposite (mirror-image) configuration, with complete loss of rotatory power because of the statistical balance between equal numbers of dextrorotatory and levorotatory molecules.

00 Hardcover QD481 This textbook for graduate students embraces asymmetric synthesis, interconversion of chiral compounds, and analytical methods for the study of racemization and diastereomerization reactions, and discusses topologically chiral assembles and molecular propellers, switches, and motors in the context of dynamic stereochemistry.
The L-Asp/D-Asp acid system was chosen motivated by the importance of LAsp acid in human metabolism, such as removing toxins from the bloodstream and the use of L-Asp racemization ratios in human serum for age estimation [46].
No racemization was observed in the synthesized homopolymers and copolymers, because of the quasi-living character of this type of cycloaddition reaction, as previously reported (14-16), (26-28); the racemization by transesterification reaction should be characterized by the presence of multiple carbonyl peaks (170.
