Cholesteric
Definition:
(a.) Pertaining to cholesterin, or obtained from it; as, cholesteric acid.

(16) Furthermore, replica morphologies were strikingly similar to TEM images of dinoflagellate chromosomes in both thin section and freeze-etch replicas, providing strong support for the cholesteric DNA packing model proposed for the organization of DNA in these chromosomes by Bouligand and Livolant.
(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.
Molecule
Definition:
(n.) One of the very small invisible particles of which all matter is supposed to consist.
(n.) The smallest part of any substance which possesses the characteristic properties and qualities of that substance, and which can exist alone in a free state.
(n.) A group of atoms so united and combined by chemical affinity that they form a complete, integrated whole, being the smallest portion of any particular compound that can exist in a free state; as, a molecule of water consists of two atoms of hydrogen and one of oxygen. Cf. Atom.
Example Sentences:
(1) A series of human cDNA clones of various sizes and relative localizations to the mRNA molecule were isolated by using the human p53-H14 (2.35-kilobase) cDNA probe which we previously cloned.
(2) Glucocorticoids have numerous effects some of which are permissive; steroids are thus important not only for what they do, but also for what they permit or enable other hormones and signal molecules to do.
(3) The results demonstrated that K2PtCl4 was bound to a greater degree than CDDP in this system with 3-5 and 1-2 platinum atoms respectively, bound per transferrin molecule.
(4) Complementarity determining regions (CDR) are conserved to different extents, with the first CDR region in all family members being among the most conserved segments of the molecule.
(5) Even with hepatic lipase, phospholipid hydrolysis could not deplete VLDL and IDL of sufficient phospholipid molecules to account for the loss of surface phospholipid that accompanies triacylglycerol hydrolysis and decreasing core volume as LDL is formed (or for conversion of HDL2 to HDL3).
(6) However, the presence of these two molecules was restored if testosterone was supplemented immediately after orchiectomy.
(7) In the second approach, attachment sites of DTPA groups were directed away from the active region of the molecule by having fragment E1,2 bound in complex, with its active sites protected during the derivatization.
(8) PMNs could be primed for PMA-triggered oxidative burst by muramyl peptide molecules (MDP) and two of its adjuvant active nonpyrogenic derivatives.
