Acylglycerols glycerides

Complex mixtures of acylglycerols are the major components of naturally occuring fats and oils. Oils are fats that are liquid at room temperature. Their liquidity is attributed to their acid residues having a high proportion of C = C bonds. Triacylglycerols are the predominant energy store in animals and are mainly located in adipose tissue. 

Metabolism of fats is responsible for supplying a significant part of the energy requirements of many cells. Initially the fat is hydrolysed to glycerol and the appropriate fatty acids. Metabolic oxidation of these fatty acids liberates energy in a form that can be utilized by the cell.

Because they are uncharged, acylglycerols (glycerides), cholesterol, and cholesteryl esters are termed neutral lipids. 

This enzyme [EC 2.7.S.2] (also known as CDP-choline l,2-diacylglycerol cholinephosphotransferase, diacylglycerol cholinephosphotransferase, phosphoryl-choline glyceride transferase, alkylacylglycerol cholinephosphotransferase, and l-alkyl-2-acetylglycerol cholinephosphotransferase) catalyzes the reaction of CDP-choline with 1,2-diacylglycerol to produce CMP and a phosphatidylcholine. l-Alkyl-2-acylglycerol derivatives can also serve as substrates. 

Glycerides (acylglycerols). General name for fatty acid esters of glycerol. Depending on the number of fatty acids esterified with one molecule of glycerol the G. are classified as mono-, di-, and triglycerides. 

Acylglycerols are esters of glycerol (propane-1,2,3-triol) and fatty acids. Partial glycerides are important intermediates in metabolism and triacylglycerols are the major constituents of natural fats and oils. 

Triacylglycerols are esters of glycerol in which each of the three hydroxyl groups is esterified with a fatty acid. Partial glycerides have one or two hydroxyls esterified and are mono- or diacylglycerols, respectively (Fig. 1). When acylglycerols contain hydroxy acids (such as the ricinoleic acid... 

Arachidic acid, icosanoic acid CH3-(CH2)ig-COOH, a fatty acid, Af, 312.5, m.p. 75.3 °C. It occurs widely as a component of glycerides (acylglycerols), but is usually present only in low concentrations. In sunflower oil, soybean oil, milk fat and peanut oil, A. a. may represent up to 3 % of the esterified fatty acids. 

Fats are esters of fatty acids with the trihydric alcohol glycerol they are also referred to as glycerides or acylglycerols.When all three alcohol groups are esterified by fatty acids, the compound is a triacylglycerol (triglyceride) ... 

The hydrolases catalyse hydrolytic cleavage. Typical are the hydrolyses associated with fat and protein digestion, which are essential for the normal functioning of the organism. A fat may be broken down to glycerides (acylglycerols) and fatty acids under the influence of a lipase ... 

Glycerides are desirable for biodiesel production mainly for alkaline transesterifications (Chisti 2007). Acylglycerols generally have a lower degree of unsaturation than other lipid fractions (i.e., polar lipids) and produce FAME with higher oxidation stability (Hahm et al. 2012). 

Acylglycerols (formerly called glycerides) are esters in which one, two or three fatty acids have reacted with the alcohol, glycerol. The two CHjOH groups of glycerol cause difficulties for D, l nomenclature (Section 1.3). The remedy was the introduction of...
