Subsequently, many scholars use dentin translucency, cementum ring structure, amino acid racemization
, and modified Gustafson method for age estimation (Singh et al.
glycation end-products (AGEs), (4) aspartic acid racemization
Age and growth estimates of Bowhead Whales (Balaena mysticetus) via aspartic acid racemization
Age estimates based on aspartic acid racemization
for bowhead whales (Balaena mysticetus) harvested in 1998-2000 and the relationship between racemization
rate and body temperature.
This 23-chapter book explores mechanisms linking aging, disease, and biological age estimation, focusing on four of the hallmarks of aging--aspartic acid racemization
, advanced glycation endproducts, telomere shortening, and mitochondrial DNA mutations--and their role in aging and diseases and their application in age-at-death estimation in forensic sciences.
Notably, the CTX octapeptide also contains an aspartyl that gradually undergoes isomerization and racemization
, converting from the newly synthesized form ([alpha]CTX) to an isomerized form ([beta]CTX) over time.
In the presence of base racemization
also occur which also preferentially leads to the reduction of yield and makes purification difficult.
Thus, no detectable racemization
took place under the conditions of the Pd-catalyzed vinylation.
usually comes about as a result of faulty manufacturing procedures, such as at the point that laetrile was extracted from its source in apricot kernels in a substandard factory.

In the samples prepared with a tin(II) 2-ethylhexanoate as the catalyst, racemization
can occur during polymerization, which strongly influences stereoregularity of poly(L-lactide), even with the isosorbide in the main chains.
