Lipids

Lipids • Includes fats, phospholipids, and steroids

Building Blocks

Building Blocks • Glycerol

Building Blocks • Glycerol • Fatty acid

Building Blocks • Glycerol • Fatty acid – Long carbon chain with a carboxyl group at one end

Building Blocks • Glycerol • Fatty acid – Long carbon chain with a carboxyl group at one end they are hydrophobic!

Lipids (aka fats or triglycerides) • Consist of 1 glycerol and 3 fatty acids

Lipids (aka fats or triglycerides) • Consist of 1 glycerol and 3 fatty acids • Condensation synthesis forms fats

Lipids (aka fats or triglycerides) • Consist of 1 glycerol and 3 fatty acids • Condensation synthesis forms fats

Lipids (aka fats or triglycerides) • Consist of 1 glycerol and 3 fatty acids • Condensation synthesis forms fats • Some fats are saturated or unsaturated

Lipids (aka fats or triglycerides) • Consist of 1 glycerol and 3 fatty acids • Condensation synthesis forms fats • Some fats are saturated or unsaturated

Lipids (aka fats or triglycerides) • Consist of 1 glycerol and 3 fatty acids • Condensation synthesis forms fats • Some fats are saturated or unsaturated – Bending occurs in unsaturated fats

Lipids (aka fats or triglycerides) • Consist of 1 glycerol and 3 fatty acids • Condensation synthesis forms fats • Ex. Butyric acid, palmitic acid

Lipids (aka fats or triglycerides) • Functions – energy storage (by mass fats have twice the energy of carbs and proteins)

Lipids (aka fats or triglycerides) • Functions – energy storage (by mass fats have twice the energy of carbs and proteins) as adipose cells in animals and seeds in plants

Lipids (aka fats or triglycerides) • Functions – energy storage (by mass fats have twice the energy of carbs and proteins) as adipose cells in animals and seeds in plants – Thermal insulation
