Are insoluble in water but dissolve readily in other lipids and organic solvents such as alcohol and ether
Lipids
Commonly known as fats when solid or oils when liquid
Triglycerides (neutral fats)
Are linear chains of carbon and hydrogen atoms (hydrocarbon chains) with an organic acid group (-COOH) at one end
Fatty acids
Is a modified simple sugar (a sugar alcohol)
Glycerol
Fatty acid chains with only single covalent bonds between carbon atoms
Saturated
Fatty acids that contain one or more double bonds between carbon atoms
Unsaturated (monounsaturated or polyunsaturated respectively)
Oils that have been solidified by addition of H atoms at sites of carbon double bonds
Trans fat
Found naturally in cold water fish
Omega-3 fatty acids
Are modified triglycerides
Phospholipids
Are basically flat molecules made of 4 interlocking hydrocarbon rings
Steroids
Are diverse lipids chiefly derived from a 20-carbon fatty acid (arachnid Knox acid) found in all cell membranes
Eicosanoids
Composes 10-30% of cell mass and is the basic structural material of the body
Protein
The building blocks of proteins are molecules called…. Of which there are 20 common types
Amino acids
Peptide bond
Large complex molecules containing from 100 to over 10,000 amino acids
Macromolecule
