Glyceride vs. Glycerol — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Updated on April 19, 2024
Glyceride is a type of molecule formed from glycerol and fatty acids, involved in fat storage; glycerol is a simple polyol compound, essential in forming triglycerides and other lipids.

Key Differences
Glycerides, which include triglycerides, are esters formed from glycerol and fatty acids, serving primarily as fat storage in animals and plants. Glycerol, a colorless, odorless liquid with a sweet taste, functions independently as a humectant in pharmaceuticals and cosmetics.
Glyceride molecules are key components in biological lipids and play critical roles in energy metabolism and cellular structure. Glycerol, on the other hand, is often used in food industry as a solvent, sweetener, and preservative, highlighting its versatility beyond lipid structure.
In the structure of glycerides, glycerol acts as a backbone by bonding with up to three fatty acids, forming monoglycerides, diglycerides, or triglycerides depending on the number of fatty acid groups attached. Whereas glycerol itself is a trihydroxy alcohol, free of fatty acids and not involved in direct energy storage.
The production of glycerides in the body involves enzymatic processes that attach fatty acids to the glycerol molecule. Glycerol production, however, typically results from the breakdown of these glycerides during metabolism or from dietary sources directly.

Glyceride
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 configurations and positions of olefins.
Glycerol
Glycerol (; also called glycerine in British English or glycerin in American English) is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic.
Glyceride
An ester formed between one or more fatty acids and glycerol. Glycerides are found in plant oils and animal fats.
Glycerol
A colourless, sweet, viscous liquid formed as a by-product in soap manufacture. It is used as an emollient and laxative, and for making explosives and antifreeze.

Common Curiosities
What role does glyceride play in the human body?
In the human body, glycerides serve as a major form of energy storage, especially in adipose (fat) tissues.
Are glycerides considered fats?
Yes, glycerides are a type of fat, specifically triglycerides, which are commonly found in both food and the human body.
How does glycerol support energy metabolism?
Glycerol can be metabolized into glucose, providing a source of energy, especially during fasting or intense physical activity.
What impact does the breakdown of glycerides have on the body?
The breakdown of glycerides releases fatty acids and glycerol, which are used for energy production or other metabolic processes in the body.
Why are glycerides important in biodiesel production?
Glycerides are important in biodiesel production because they undergo a process called transesterification, which transforms them into biodiesel and glycerol.
What is a common industrial use of glycerol outside of the food industry?
In the industrial sector, glycerol is used as a cryoprotectant, antifreeze, and in the manufacture of explosives like nitroglycerin.
Is glycerol only derived from animal sources?
No, glycerol can be derived from both animal and plant sources, particularly from the hydrolysis of triglycerides in these sources.
What are the dietary sources of glycerides?
Dietary sources of glycerides include most fats and oils, such as butter, vegetable oil, and animal fats.
What is the relationship between glycerol and triglycerides?
Glycerol is a fundamental component of triglycerides, linking with three fatty acids to form the primary storage form of fat in animals.
How is glycerol used in skin care products?
In skin care products, glycerol is used as a humectant to help maintain moisture in the skin by attracting water from the air.
Can glycerides be synthesized artificially?
Yes, glycerides can be synthesized in industrial processes, often used in the production of foods and biodiesel.
Can the human body produce glycerol independently of dietary intake?
The human body can produce glycerol through the breakdown of triglycerides and other lipids during metabolic processes, independent of dietary intake.
How does glycerol contribute to the food industry outside of being a sweetener?
Besides being a sweetener, glycerol serves as a solvent and texture enhancer in various food products, improving shelf life and consistency.
