What's the difference between cholesteric and compound?
Cholesteric
Definition:

(17) A pitch length of approximately 2.5 microns for the cholesteric phase was determined both from optical measurements (optical light rotation) and from NMR measurements (solvent diffusion).
(18) The steady-state anisotropy of dehydroergosterol in LDL detected the cholesteric core phase transition near 30 degrees C. Fluorescence lifetime decays for dehydroergosterol contained two components, both below and above the cholesteric phase transition, with the major lifetime component near 1 ns.
(19) The possible morphogenetic role of the glucuronoxylans in the cholesteric organization of the cellulose is discussed.
(20) The densification and especially the expansion modes suggest considerable fluidity in the developing chorion, consistent with its proposed cholesteric liquid crystalline structure.

(v. t.) Composed of two or more elements, ingredients, parts; produced by the union of several ingredients, parts, or things; composite; as, a compound word.
(n.) That which is compounded or formed by the union or mixture of elements ingredients, or parts; a combination of simples; a compound word; the result of composition.
(n.) A union of two or more ingredients in definite proportions by weight, so combined as to form a distinct substance; as, water is a compound of oxygen and hydrogen.
Example Sentences:
(1) These factors might account for the lower systemic bioavailability of these compounds.
(2) The interaction of the antibody with both the bacterial and the tissue derived polysialic acids suggests that the conformational epitope critical for the interaction is formed by both classes of compounds.
(3) These organic compounds were found to be stable on the sorbent tubes for at least seven days.
(4) Compound Z has the properties expected of an oxidized MPT precursor.
(5) Although Jeggo's Chinese hamster ovary cells were more responsive to mAMSA, novo still abrogated mAMSA toxicity in the mutant cells as well as in the parental Chinese hamster ovary cells 2,4-Dinitrophenol acted similarly to novo with respect to mAMSA killing, but neither compound reduced the ATP content of V79 cells.
(6) Recent data collected by the Games Outcomes Project and shared on the website Gamasutra backs up the view that crunch compounds these problems rather than solving them.
