For example sn-glycero-3-phosphoric acid and sn-glycero-1-phosphoric acid are enantiomers. Most vegetable oils have unsaturated fatty acids in the sn-2 position, with saturated fatty acids in the 1-sn and/or 3-sn position. [8] Animal fats more often have saturated fatty acids in the 2-sn, with unsaturated fatty acids in the 1-sn and/or 3-sn ...
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]
Triglyceride 3 NaOH / H 2 O Δ 3 × soap 3 × glycerol Triglycerides can be saponified with sodium hydroxide to give glycerol and fatty sodium salt or soap. Typical plant sources include soybeans or palm. Animal-derived tallow is another source. From 2000 to 2004, approximately 950,000 tons per year were produced in the United States and Europe; 350,000 tons of glycerol were produced in the U ...
Saturated fatty acids 16 and 18 carbons in length are the dominant types in the epidermis, [38] [39] while unsaturated fatty acids and saturated fatty acids of various other lengths are also present. [ 38 ] [ 39 ] The relative abundance of the different fatty acids in the epidermis is dependent on the body site the skin is covering. [ 39 ]
The word "triacylglycerol" is sometimes used synonymously with "triglyceride". In these compounds, the three hydroxyl groups of glycerol are each esterified, typically by different fatty acids. Because they function as an energy store, these lipids comprise the bulk of storage fat in animal tissues.
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. A triglyceride (from tri-and glyceride; also TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids. [1]
Phospholipids [1] are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group and two hydrophobic "tails" derived from fatty acids, joined by an alcohol residue (usually a glycerol molecule). Marine phospholipids typically have omega-3 fatty acids EPA and DHA integrated as part of the phospholipid molecule. [2]
A saturated fat is a type of fat in which the fatty acid chains have all single bonds between the carbon atoms. A fat known as a glyceride is made of two kinds of smaller molecules: a short glycerol backbone and fatty acids that each contain a long linear or branched chain of carbon (C) atoms.
