Nonpolar hull

To determine whether pharmacological differences are dictated by differences in nonpolar accessible surfaces of the targets within ligand-binding sites, a nonpolar distance, dnp (i,j), between the affinity-assayed kinases i, j is introduced. The dnp (i,j) is determined by differences in accessible nonpolar surface areas of the respective nonpolar hulls, Hnp ( ), Hnp (j). As rigorously defined in the previous... 

The greatest portion of the lipids in barley kernel is nonpolar lipids (67-78%). The compositions of lipids in the embryonic axis, bran endosperm, and hull fractions of hulless barley caryopses were determined by Price and Parsons (124) (Table 27). Neutral lipids were predominant in all fractions. Phospholipid content of barley hull was lower than that of the bran endosperm and embryonic axis. The hull fraction contained the highest glycolipid amount among the grain fractions. 

Bark fibers, which would be expected to have a non-polar (ligninlike) surface gave good results when used as a filler in nonpolar thermoplastics. Likewise, peanut hull flour and walnut shell flour, which are rich in phenolic, lignin-like material, are relatively good fillers. Treatment of the surface of rice hull flour to increase its compatability with thermoplastic resins has been shown to greatly enhance its value as a filler. None of the shell flours are fibrous.
