Document Summary

Macromolecules: a molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer. Lipids: constitute the plasma membrane; hydrophobic carbon chain with oxygen double bonded to carbon bonded to oxygen; functions outside of the cell membrane; examples: oil, fat, wax, phospholipid, cholesterol, hormones. Phospholipids: a lipid containing a phosphate group in its molecule, e. g. , lecithin. Fatty acids: a carboxylic acid consisting of a hydrocarbon chain and a terminal carboxyl group, especially any of those occurring as esters in fats and oils; example: palmitoleic acid. Saturated fats: a type of fat containing a high proportion of fatty acid molecules without double bonds, considered to be less healthy in the diet than unsaturated fat. Unsaturated fats: an unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain.
