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
