, Introduction
• Lipids are made of carbon, hydrogen and oxygen (the ratio of oxygen is less
than that of carbohydrates.
• Serves as an energy source
• Water-insoluble (hydrophobic) organic molecules, therefore are generally
compartmentalized in the cells.
• They are found in different forms,
Membrane-associated
Droplets of triacylglycerols in
adipocytes
Associated with proteins
(Lipoproteins) in the blood)
Functions of lipids
Protect organs from injuries and
Serves as an energy source
physical stress – Kidney
Homeostasis -By
provide the hydrophobic barrier Insulation
prostaglandins and steroid
hormones
Different Types of Lipids and Their Structure
Triacylglycerol /Triglycerides
• The major form of storage
Glycerol + 3 Fatty acid molecules = Triglyceride
