Racemization - Wikipedia
WEBIn chemistry, racemization is a conversion, by heat or by chemical reaction, of an optically active compound into a racemic (optically inactive) form. This creates a 1:1 molar ratio of enantiomers and is referred to as a racemic mixture (i.e. contain equal amount of …

WEBThe racemization of an optically active secondary halide with the chiral carbon carrying the halogen (e.g., 2-chlorobutane) may occur ih solution and, usually, the more polar and better ionizing the solvent is, the more readily the substance is racemized.
Chirality, Racemisation and Optical activity of Haloalkanes - BYJU'S
WEBRacemisation is defined as “a process by which an optically active substance either dextro or levorotatory, is directly converted into a racemate”. Resolution is the method when a racemic modification is divided into its constituent enantiomers.
Racemization Overview, Mechanism & Examples - Lesson
WEBNov 21, 2023 · Racemization is a process in organic chemistry that occurs when a compound undergoes a reaction in which the transformation produces an equal mixture of both possible enantiomers.
Racemization - an overview | ScienceDirect Topics
WEBRacemization is the alteration of l-amino acids to d, l-mixtures. With the exception of Gly, all the mammalian amino acids are chiral at the carbon bearing chain and are susceptible to base-catalyzed racemization. Racemization may form peptide bonds that are sensitive to proteolytic enzymes.
Racemization - an overview | ScienceDirect Topics
WEBRacemization is the conversion of the naturally produced pure l-amino acids into a racemic mixture of D- and L-forms. The rates of conversion are slow and temperature dependent, so measuring the ratio of D/L gives the age of a protein.
Racemisation in Chemistry and Biology
WEBNov 10, 2019 · The authors reviewed the available data concerning the process of racemisation in vivo, in the presence of biological molecules (e.g., racemase enzymes, serum albumin, cofactors and derivatives) and under purely chemical but aqueous conditions (acid, base and other aqueous systems).
Racemization - an overview | ScienceDirect Topics
WEBRacemization of amino acids is the spontaneous conversion of l-enantiomers to the d-form, which is dependent on temperature, pH, and time. Because of the time-dependent nature of racemization, it can be used to determine the relative …
Racemization, enantiomerization, diastereomerization, and epimerization ...
WEBRacemization relates to the macroscopic and statistical process of the irreversible transformation of one of the enantiomers into the racemic mixture. Enantiomerization refers to the microscopic and molecule process of the …
Amino Acid Racemization - American Chemical Society
WEBRacemization is the process in which one enantiomer of a compound, such as an L-amino acid, converts to the other enantiomer. The compound then alternates between each form while the ratio between the (+) and (–) groups approaches 1:1, at which point it becomes optically inactive.
