Lipids
Composed of C, H and few O
Basic unit is fatty acid (glyceride)
Triglyceride is the major form of lipid = 3 fatty acids
Fats and oils
Monounsaturated Fatty Acids
Polyunsaturated Fatty Acids
Saturated Fatty Acids
Essential Fatty Acids
Energy yielding (9 kcal /gm)
Sources of Dietary Lipids
Properties of Lipids
• Do not readily dissolve in water
• Fats are solid at room temperature
• Oils are liquid at room temperature
• Triglycerides are the main form of lipids in food and body (storage)
• Energy dense (9 kcal /gm)
The building block of lipids are fatty acids
omega end alpha end Note that all carbons have two hydrogens – this is a fully saturated fatty acid.
