Fatty acid profiles are obtained after chemical ester hydrolysis, derivatisation and chromatography, for position 2 (from the 2acylglycerol), for 1+2, from the phosphorylated compound, yielding the composition for position 1 by difference, and for position 3 from the 2,3diacylglycerol, and also from the composition obtained for the fatty acids resulting from lysis of 1+3 ester bonds when preparing the 2acylglycerol.

HPLC. This implies that certain additive and constitutive properties of the fatty acids may be comprised by increments and can be calculated within limits. These calculable properties may be empirically correlated with the corresponding HPLC retention times of appropriate fatty acid derivatives such as phenacyl esters.

Nonalcoholic fatty liver disease (NAFLD) is a continuum of diseases that include simple steatosis and nonalcoholic steatohepatitis (NASH) ultimately leading to cirrhosis, hepatocellular carcinoma and end stage liver failure. Currently there is no approved treatment for NASH. It is known that bile acids not only have physiological roles in lipid digestion but also have strong hormonal properties.
