What's the difference between hexone and hydrocarbon?
Hexone
Definition:
(n.) A liquid hydrocarbon, C6H8, of the valylene series, obtained from distillation products of certain fats and gums.
Example Sentences:

Infectious virus production was initiated within 2 to 6 h after shift-down to 32 degrees C; de novo protein synthesis was required to allow this increase in viral titer.

(11) We conclude that the hexon protrusions are domains of VP5 hexamers, other parts of these molecules forming the basic matrix of the capsid shell to which the other proteins are attached at specific sites.
(12) To identify the latter, peptides were synthesized corresponding to residues 281 to 292 from loop 1 and 441 to 455 from loop 2 of the Ad2 hexon.
(13) In the early phase of the crystallization, groups of a few hexons began to appear, then the two-dimensional crystal lattices grew gradually to a size of 1-2 micron.
(14) Several primers, including primers specific for the hexon-coding region and for enteric adenovirus types 40 and 41, were evaluated.
(15) In contrast to this, the native capsomer (hexon) of Ad h 1 kappa exhibited lower electrophoretic mobility in agarose gel electrophoresis than the native hexon of Ad h 1B.
(16) The trypsinolysis of native SA7 hexon leads to a stable molecular "core" containing 4-5 fragment species of 10 to 65 kDa and resembling the intact capsomer in quarternary structure (trimer).
(17) The isolated antibodies showed a specific neutralizing capacity five times higher than that of the corresponding unfractionated polyclonal anti-hexon serum; however, the neutralizing ability was independent of pH.
(18) According to this criterion for chemical relatedness, about two-thirds of the type 2 and 5 hexon peptides may be considered similar.
(19) Peptides with identical isoelectric points, but from different hexon types, were considered to have structural similarities.
(20) Comparative studies showed no physico-chemical, immunological or electron microscopic differences between soluble hexons of extracellular and intracellular origin.
Hydrocarbon
Definition:
(n.) A compound containing only hydrogen and carbon, as methane, benzene, etc.; also, by extension, any of their derivatives.
Example Sentences:

(2) Aryl hydrocarbon hydroxylase (AHH) inducibility, carbon monoxide in expired air (CO), serum gammaglutamyl-transferase (GGT), and total cholesterol were compared in equal-sized, age-matched samples of healthy middle-aged males born in 1921, 1934-1936, and 1946 attending the ongoing preventive medical population program in Malmö.
(3) The length of the hydrocarbon chains of the surface-modified silica supports had no significant influence on the selectivity.
(4) The specificity of binding to microsomal proteins of metabolically activated hydrocarbons has been studied.
(5) Aryl hydrocarbon (benzo(a)pyrene) hydroxylase is present and inducible in Buffalo rat liver cells in culture.
(6) The possible occupational cause of the disease, as more solvents in the mud have the structure of aromatic hydrocarbons is discussed.
(7) Experiments with a series of adsorbents homologous with CPAD-Sepharose, in which the length of the hydrocarbon chain was varied, provided strong evidence of hydrophobic interactions, in addition to ionic interactions, in the binding of these proteins to CPAD-Sepharose.
(8) In the hydrocarbon promotion study, dose related increases were observed in the incidence of ACF in male rats promoted with UG or 50 ppm TMP for 24 or 60 weeks.
(9) The results also demonstrated that there was not any apparent correlation between the receptor-binding avidities and in vitro monooxygenase enzyme-induction potencies for the most active polynuclear aromatic hydrocarbons.
(10) Both main-stream and side-stream cigarette smoke condensates and some fractions, containing water-soluble bases, water-insoluble bases, and polycyclic aromatic hydrocarbons, were found to induce AHH activity in lung and liver, the lung being induced to the greatest extent.
(11) Pancreas transplantation offers the possibility of preventing the development and progression of diabetic lesions by adequate control of hydrocarbon metabolism.
(12) A comparison of the relative cytosolic Ah (9S) receptor binding affinities and aryl hydrocarbon hydroxylase (AHH) induction potencies of these hydrocarbons with their 4S protein binding affinities demonstrated the following: five compounds, namely 1,2,5,6-dibenz[a]-anthracene, 1,2,3,4-dibenz[a]anthracene, picene, benzo[a]pyrene and 3-methylcholanthrene exhibited high to moderate binding affinities for the 4S and 9S cytosolic proteins (EC50 values less than 10(-6) M) and induced AHH in rat hepatoma cells; three compounds, namely perylene, benzo[e]pyrene and benzo[g,h,i]perylene exhibited high affinities for the 4S binding protein (1.25 X 10(-7), 4.4 X 10(-8) and 2.9 X 10(-8) M, respectively) and low affinities (EC50 values greater than 10(-5) M) for the Ah receptor protein; moreover these three compounds did not induce AHH in rat hepatoma H-4-II E cells in culture.
