Lipids
Fatty acids and glycerol
-
-
-
Glycerides = ester formed from the reaction of a carboxylic acid and an alcohol. Glycerol contains 3 OH groups and can react with 1, 2 or 3 fatty acids to form a mono, di or triglyceride. Glycerides are hydrophobic
Function
-
-
Reducing heat and water loss = layer enriched with fats beneath skin --> protects from water loss and keeps heat in
-
Steroids
Common structure = 4 fused rings (3x 6C and 1x 5C) with different functional groups attached to the ring.
Some cases, the carbons in the rings are modified
-
Function
Structural --> e.g. cholesterol part of cell membranes. Determines the fluidity. Increase number of steroids = decrease fluidity
