Triglycerides are then commonly named as esters of those acids, as in glyceryl 1,2-dioleate 3-palmitate, the name for a brood pheromone of the honey bee. [8] Where the fatty acid residues in a triglyceride are all the same, names like olein (for glyceryl trioleate) and palmitin (for glyceryl tripalmitate) are common. [citation needed]
Example of an unsaturated fat triglyceride (C 55 H 98 O 6). Left part: glycerol; right part, from top to bottom: palmitic acid, oleic acid, alpha-linolenic acid. Glycerolipids are composed of mono-, di-, and tri-substituted glycerols, [30] the best-known being the fatty acid triesters of glycerol, called triglycerides. The word "triacylglycerol ...
In the process, 3 molecules of water are eliminated. The word "triglyceride" refers to the number of fatty acids esterified to one molecule of glycerol. In triglycerides, the three fatty acids are rarely similar and are thus called pure fats. For example, tripalmitin, tristearin, etc.
2 units, i.e., at intervals of 3 carbon atoms along the chain. For instance, α-linolenic acid is an 18:3 fatty acid and its three double bonds are located at positions Δ 9, Δ 12, and Δ 15. This notation can be ambiguous, as some different fatty acids can have the same C:D numbers.
Glycerol has three hydroxyl functional groups, which can be esterified with one, two, or three fatty acids to form mono-, di-, and triglycerides. [2] These structures vary in their fatty acid alkyl groups as they can contain different carbon numbers, different degrees of unsaturation, and different configurations and positions of olefins. [1]
[2] [3] The majority of lipids found in the human body from ingesting food are triglycerides and cholesterol. [4] Other types of lipids found in the body are fatty acids and membrane lipids . Lipid metabolism is often considered the digestion and absorption process of dietary fat; however, there are two sources of fats that organisms can use to ...
Animal fats are composed of triglycerides, which are a type of ester molecule in which glycerol is bonded to three fatty acids. [3] The three fatty acids that bond to the glycerol will determine the complexity and type of the triglyceride. If the three fatty acids are the same, then the triglyceride will be considered a simple triglyceride. [3]
A special kind of protein, called apolipoprotein, is embedded in the outer shell, both stabilising the complex and giving it a functional identity that determines its role. Plasma lipoprotein particles are commonly divided into five main classes, based on size, lipid composition, and apolipoprotein content: HDL , LDL , IDL , VLDL and chylomicrons .
