WebMar 29, 2024 · 1. Glycerol (glycerin) is polar molecule with three hydroxy groups. Fats are tri-esters of glycerol and very long-chained fatty acids, and hence relatively non polar molecules. Thus it is safe to assume that fats might not be dissolved in glycerol and vise versa. This assumption is based on the fact that glycerol is insoluble in biodiesel (Ref.1).

Glycerides, more correctly known as acylglycerols, are esters formed from glycerol and fatty acids, and are generally very hydrophobic. Glycerol has three hydroxyl functional groups, which can be esterified with one, two, or three fatty acids to form mono-, di-, and triglycerides. These structures vary in their fatty acid alkyl groups as they can contain different carbon numbers, different degrees of unsaturation, and different confi… WebDec 20, 2024 · Mixed partial esters formed by reacting polymerised glycerols with edible fats, oils or fatty acids; minor amounts of mono-, di- and triglycerides, free glycerol and polyglycerols, free fatty acids and sodium salts of fatty acids may be present; degree of polymerisation varies, and is specified by a number (such as tri-) that is related to the ... can you tame a leopard in minecraft
