A Level Biology Revision "Triglycerides"
Freesciencelessons・4 minutes read
Lipids, such as triglycerides, are essential for various functions in the human body, serving as a major energy source, storing energy, and forming cell membranes through esterification. Fatty acids, whether saturated or unsaturated, play a crucial role in the composition of these important molecules.
Insights
- Lipids, such as fats and oils, play crucial roles in the human body, serving as a key energy source, insulating the body, forming cell membranes, and more.
- Triglycerides, a specific type of lipid, are formed through esterification by combining glycerol with three fatty acid molecules, creating a hydrophobic energy source due to its non-polar nature.

Functions and Formation of Triglycerides
- Lipids, found in fats and oils, serve various functions including being a major energy source in the human diet, storing energy in adipose tissue, insulating the body, waterproofing, and forming cell membranes.
- Triglycerides, a type of lipid, consist of glycerol bonded to three fatty acid molecules. Fatty acids can be saturated or unsaturated, with the latter containing double covalent bonds.
- Triglycerides are formed through esterification, where glycerol reacts with three fatty acid molecules to create a non-polar molecule that is hydrophobic and serves as a significant energy source in the human diet.
