Examples of derrived lipids
Substances (derrived from lipids through hydrolosis)
- cholesterol
- fatty acids
Essential fatty acids
In fatty acids, as chain length increases, solubility in water
Decreases
In fatty acids, as chain length increases, the melting point
Increases
In fatty acids, as saturation increases, melting point
Increases
In fatty acids, unsaturation increases as oxidation
Increases
No double bonds
Saturated
One double bond
Monosaturated
More than one double bond
Polysaturated
Three groups of essential fatty acids
Linoleic
Linolenic
Arachidonic
Functions of lipids
Energy
Heat, insulation
Essential fatty acids
