8. Lipids defined
a diverse group of compounds found in all living cells, insoluble in water but soluble in organic solvents such as ether, acetone and chloroform, and which include fats, oils, triacylglycerols, fatty acids, glycolipids, phospholipids and steroids, some lipids being essential components of biological membranes, others acting as energy stores and fuel molecules for cells.

9. Lipids classified
    -fatty acids
            -straight hydrocarbon chain terminating with a carboxylic acid group
