Examples Fats Oils Waxes Steroids

Functions Long-term energy storage Main component of cell membranes Hormones Insulation/cushioning

Structure Long chains of carbon (and hydrogen) Two primary molecules: Glycerol Fatty Acids

Glycerol A simple 3-carbon alcohol

Fatty Acids

Saturated vs Unsaturated

Saturated Fatty acids Saturated fatty acids have the maximum number of hydrogen Known as FATS Generally found in animal sources Solids at room temperature

Unsaturated Fatty Acids Have two or more hydrogen replaced with double- bonds Known as OILS Generally found from plant sources Liquid at room temperature

Cis- vs Trans- Fatty acids

Cis- vs Trans- fatty acids Cis-fatty acids have the carbon on the same side of the double-bond Trans-fatty acids have carbons on different sides of the double bond Cis-fatty acids produce a bend in the molecule

Cis- vs Trans- Fatty acids

Degrees of Saturation

Polyunsaturated Fats Have more than one double bond

Triglycerides

One glycerol + 3 Fatty Acids  Triglyceride Can have 3 different fatty acids hydrophobic

Phospholipids Consist of glycerol, two fatty acids and one phosphate group

Phospholipids Are amphiphilic Make up cell membranes

Steroids Consist of a four-carbon ring Basis for many hormones

Steroid Hormones
