Selective Esterification of Phosphonic Acids [PDF]

open access: yesMolecules, 2021
Here, we report straightforward and selective synthetic procedures for mono- and diesterification of phosphonic acids. A series of alkoxy group donors were studied and triethyl orthoacetate was found to be the best reagent as well as a solvent for the performed transformations.

The synthesis of phosphinates: traditional versus green chemical approaches

open access: yesGreen Processing and Synthesis, 2014
Three alternatives are discussed in comparison with the classical esterification of phosphinic chlorides by reaction with alcohols. All novel methods, such as microwave (MW)-assisted direct esterification, MW-assisted phase transfer catalyzed alkylating ...

In vitro esterification of cholesterol by pancreatic juice and by acetone powder extracts of small intestine: the effect of unsaturated fatty acids upon esterification with saturated fatty acids

open access: yesJournal of Lipid Research, 1965
The esterification of cholesterol by rat pancreatic juice and by extracts of acetone powders of rat small intestine was studied with palmitic, stearic, oleic, linoleic, and linolenic acids.

Tissue expression studies on the mouse acyl-CoA: cholesterol acyltransferase gene (Acact): findings supporting the existence of multiple cholesterol esterification enzymes in mice

open access: yesJournal of Lipid Research, 1997
Cholesterol esterification is involved in the regulation of cellular cholesterol content and has been hypothesized to play a role in important physiologic processes including intestinal cholesterol absorption, hepatic lipoprotein production, and ...

Preparation and Properties of Normal Temperature Cured Starch-Based Wood Adhesive

open access: yesBioResources, 2016
A normal temperature cured starch-based wood adhesive was prepared using dry method esterification and polyisocyanate prepolymer crosslinking. The effects of esterification and crosslinking on the properties of corn starch adhesive were investigated. The

Lecithin:cholesterol acyltransferase (LCAT) mass; its relationship to LCAT activity and cholesterol esterification rate.

open access: yesJournal of Lipid Research, 1981
The relationship between plasma lecithin:cholesterol acyltransferase mass and enzyme activity and between mass and plasma cholesterol esterification rate was determined in 25 adult volunteers without overt disease (14 normolipidemic and 11 hyperlipidemic)

Lipase activity in alcoholysis and esterification reactions of crude latex from babaco fruit (Carica pentagona)

open access: yesOléagineux, Corps gras, Lipides, 2003
Lipase activity in alcoholysis and esterification reactions were studied for crude latex from the subtropical Babaco plant (Carica pentagona). The results reveal that crude Carica pentagona latex exhibits equivalent biocatalytic properties in synthesis ...
