Step-by-step explanation:
Detailed Answer to Your Question About Lipids, The correct name for fat molecules, which are one of the major classes of lipids, is triglycerides or triacylglycerols. These lipids are made up of a glycerol molecule that is esterified with three fatty acid chains.
The fatty acids in triglycerides can be either saturated, containing no carbon-carbon double bonds, or unsaturated, containing one or more carbon-carbon double bonds. Triglycerides serve as a long-term energy storage in living organisms, provide insulation, and help to maintain cell membrane integrity.
The saturated fats typically come from animal sources, while unsaturated fats often come from plant sources and can have health benefits when included as part of a balanced diet.
