Uses of Lipids

• Long-term energy storage• Biological membranes• Chemical messengers• Waterproof coverings.

Types of Lipids• Fats - lipids that are made with one glycerol

molecule and three fatty acid chains. – Used for long-term energy storage, protection,

and insulation.

Types of Fat:Saturated

Unsaturated

Types of Lipids

• Phospholipids - lipids that have a polar headand two non-polar tails.– Major component of cell membranes.

Types of Lipids

• Steroids - lipids that contain four carbon rings. – Serve as chemical messengers in the body.

Types of Lipids

• Waxes - lipids that are made from alcohol and fat.– Used for waterproof coverings.
