Herein, we characterize N-acyl amino acids (NAAs) as a model protoamphiphilic system. To the best of our knowledge, we report a new abiotic route in this study for their synthesis under wet-dry cycles from amino acids and monoglycerides via an ester-amide exchange process. We also ...
Process for preparing racemic amino acids, characterized in that an acylamino acid of the general formula R 1 -CH (NH-CO-R2) COOH wherein R1 is a linear, branched or cyclic alkyl having from 1-7 carbon atoms and it contains an alkylthio group as a substituent; R2 represents a hydrogen...
Using the targeted lipidomics approach, more than 50 endogenous acyl amino acids have been identified and 11 of them were even quantified from rat brain by nano-LC–MS/MS (Tan et al., 2009, 2010). The vast scope of potential ‘headgroup’ moieties of NAAs make them valuable ...
The invention relates to a method for preparing an N-fatty acyl amino acid type surfactant by fat and belongs to the technical field of synthesis of organic compounds. In a technology for synthesizing the N-fatty acyl amino acid type surfactant, the fat replaces acyl chloride, so that the ...
