Quick Reference
Also Known AsTriglyceride, triacylglycerol, lipid, dietary fat

What is Fat?

Fats are a subgroup of lipids — naturally occurring triglycerides (triesters of glycerol with three fatty acid molecules). They are solid or semi-solid at room temperature, distinguishing them from oils which are liquid. Fats are essential macronutrients that store energy, support cell growth, protect organs, and help absorb fat-soluble vitamins.

Properties & Characteristics

Chemical class: triglycerides (triacylglycerols). Composed of glycerol + 3 fatty acid chains. Saturated fats: single bonds, solid at room temperature. Unsaturated fats: double bonds, lower melting point. Density: ~0.91 g/cm³. Insoluble in water, soluble in organic solvents.

Uses & Applications

Energy storage in living organisms (9 kcal/g). Food ingredient and cooking medium. Manufacturing soaps and detergents (saponification). Lubricants and greases. Biodiesel production. Pharmaceuticals and cosmetics. Vitamin delivery (fat-soluble vitamins A, D, E, K).

Safety Information

Excessive dietary intake linked to cardiovascular disease and obesity. Rancidity: oxidation produces harmful aldehydes and ketones. Trans fats (hydrogenated) associated with increased health risks. Fire hazard when heated to high temperatures (cooking fires).
