Everything about Glyceride totally explained
Glycerides, more correctly known as
acylglycerols, are
esters formed from
glycerol and
fatty acids.
Glycerol has three
hydroxyl functional groups, which can be esterified with one, two, or three fatty acids to form
monoglycerides,
diglycerides, and
triglycerides.
Vegetable oils and
animal fats contain mostly triglycerides, but are broken down by natural
enzymes (
lipases) into mono- and diglycerides and free fatty acids.
Soaps are formed from the reaction of glycerides with sodium hydroxide. Glycerol is a product that can soften dehydrated skin by absorbing moisture from the air. If pure glycerol were left exposed to normal air, in 10 to 12 hours it would become 80% glycerol and 20% water by absorbing 1/5 of its weight in water.
Partial glycerides are esters of glycerol with fatty acids, whereby only a part of the existing
hydroxyl groups are esterified. Some hydroxyl groups within the glycerol ester are free contributing
to the polaric properties of the material. Short chain partial glycerides are more
polaric and have excellent solvent properties for many hard-to-solubilize drugs.
