| nonpolar | <chemistry> Describes a molecular that does not have a permanent electric dipole and consequently may be less soluble in water (for example lipids). See: nonpolar groups (12 Mar 1998) |

| nonpolar amino acid | An alpha-amino acid in which the functional group attached to the alpha-carbon (i.e., R in RCH(NH2)COOH) has hydrophobic properties; e.g., valine, leucine, alpha-aminobutyrate. (05 Mar 2000) |
| nonpolar compound | A compound composed of molecules that possess a symmetrical distribution of charge, so that no positive or negative poles exist, and that are not ionizable in solution; e.g., hydrocarbons. See: organic compound. (05 Mar 2000) |
| nonpolar group | <chemistry> Group in which the electronic charge density is essentially uniform and that cannot therefore interact with other groups by forming hydrogen bonds or by strong dipole dipole interactions. In an aqueous environment, nonpolar groups tend to cluster together, providing a major force for the folding of macromolecules and formation of membranes. Clusters are formed chiefly because they cause a smaller increase in water structure (decrease in entropy) than dispersed groups. Nonpolar groups interact with each other only by the relatively weak London van der Waals forces. (12 Mar 1998) |
| nonpolar solvents | Organic liquids notable for their ability to dissolve lipids; usually, but not always, immiscible in water; e.g., diethyl ether, carbon tetrachloride. Synonym: nonpolar solvents. (05 Mar 2000) |
