Lecture 5 (lipds)

Unsaturated Fats

have one or more double bonds

triacylglycerol (fats) what linkage?

Glycerol (1) and fatty acids (3) joined ester linkage

phosphate group (head) OPO3

Hydrophallic

Two Fatty acids tail (of phospholipids are)

Hydrophobic

Properties of lipids (fats)

Hydrophobic Consist of mostly hydrocarbons

Steriods

Carbon skeleton of fused rings (hexose, pentonse)

Fatty Acid consist of what group?

Carboxyl (-COOH) C=O-OH

Saturate fats

Linear in shape : no double bonds

Lipids

Macromolecules but not polymers Does not have repeating subunits

Cholesterol

Steriods- subinit of fat, component in animal cell membrane. Synthesized steriods

What are components of phospholipids (3 groups)

Two fatty acids phosphate group Gylcerol

What two chemical compound makes up Fat

Two parts glycerol and fatty acids
