A NEW SYNTHESIS OF ASPARTIC ACID [PDF]
In previous syntheses of aspartic acid the following reactions have been used: The decomposition of acid ammonium malate by heat,1 the racemization of active aspartic acid2 and active asparagine,3 the reaction of maleic or fumaric acid with ammonia,4 the reduction of oxalacetic ester oxime,5 the reaction of silver fumarate or potassium acid fumarate ...

Association between the aspartic acid D-repeat polymorphisms and osteoarthritis susceptibility
Objectives: Association between the D-repeat of asporin (ASPN) gene and osteoarthritis (OA) was still inconsistent. We performed this meta-analysis to systematically assess the D-repeat polymorphisms in OA susceptibility.

Strecker degradation products of aspartic and glutamic acids and their amides
Aspartic and glutamic acids, asparagine and glutamine were oxidised with either potassium peroxodisulphate or glyoxal. Nonvolatile products were derivatised and analysed by GC/FID and GC/MS.

Mutation of aspartic acid 262 on estrogen receptor abrogates estradiol signaling pathway
Objective ERα (estrogen receptor alpha) exerts nuclear genomic actions and membrane-initiated non-genomic effects. The mutation of aspartic acid into alanine in vitro revealed the critical role of aspartic acid 258 (corresponding to mouse amino acid site
