Parts of
Fats and Oils
Glycerol and three fatty acids
Define
Triacylglycerol
A glycerol covalently bonded to three fatty acids
Fats and oils
Common feature of
Lipids
Hydrophobic, due to nonpolar bonds between carbons and hydrogens
Examples of
Lipids
Fats and oils
Waxes
Phospholipids
Cholesterol and steroids
Pigments
Define
Saturated fatty acid
A hydrocarbon with all single bonds
Each carbon in the chain is bound to two hydrogen atoms
Define
Unsaturated fatty acid
A hydrocarbon with one or more double bonds
Some of the carbon atoms in the chain are bound to only one hydrogen atom
Define
Fat
Triacylglycerides with all saturated fatty acids or trans-fatty acids, which can pack in tightly to form a solid
Define
Oil
Triacylglycerides with some cis-unsaturated fatty acids, which do not pack in tightly enough to form a solid
