What's the difference between kerasin and nitrogenous?
Kerasin
Definition:
(n.) A nitrogenous substance free from phosphorus, supposed to be present in the brain; a body closely related to cerebrin.
Example Sentences:
(1) The high transition enthalpy for kerasin is ascribed to a lesser accommodation of gauche conformers in the hydrocarbon chains just below the transition temperature.
(2) Natural kerasin was found to act isomorphic to semi-synthetic (natural configuration) D-kerasins but not completely to synthetic DL-kerasins of single acyl chain lengths.
(3) The thermodynamic behavior of these cerebroside fractions, including hysteresis in kerasin gels, is compared to that previously reported for sphingomyelins.
(4) Kerasin mixed with egg PC yields a peritectic phase diagram.
(5) The non-ideal behavior appears to be a superposition of separate interactions of kerasin and phrenosin with egg PC.
(6) Evidence for a higher degree of order in the hydrocarbon chains and a different configuration in the polar region of kerasin is supplied by Raman spectroscopic parameters for these gel phases.
(7) The thermotropic behavior of mixtures of dipalmitoylphosphatidylcholine (DPPC) with natural glycosphingolipids (galactosylceramide, phrenosine, kerasine, glucosylceramide, lactosylceramide, asialo-GM1, sulfatide, GM3, GM1, GD1a, GT1b) in dilute aqueous dispersions were studied by high sensitivity differential scanning calorimetry over the entire composition range.
(8) Kerasin in the stable and metastable gel states exhibits discontinuous and continuous ranges of miscibility, respectively, with DMPC.
(9) Bovine brain cerebroside and its kerasin (beta-D-galactosyl-N-acyl-D-sphingosine) and phrenosin (beta-D-galactosyl-N-(2-D-hydroxyacyl)-D-sphingosine) fractions were mixed with diacylphosphatidylcholines (PCs) to form fully hydrated lamellar phases.
(10) The kerasin fast pool is approximately 17% with a half-time of 29 h and the slow pool approximately 83% with a half-time of 2700 h. In contrast, semisynthetic N-palmitoylgalactosylceramide at the same temperature transfers with single-exponential kinetics with a half-time of 32 h. The half-time for N-lignoceroylgalactosylceramide under the same conditions proved to be greater than 3500 h. No concentration dependence for these half-times was found in the concentration range studied (0-10 mol%).
(11) The stable gel phase of kerasin does not segregate in natural cerebroside.
(12) The kinetics of spontaneous transfer of various glucosyl- and galactosylceramides between 1-palmitoyl-2-oleoylphosphatidylcholine vesicles have been examined at 45 degrees C. Bovine brain galactosylceramides, kerasin and phrenosin, were found to transfer with biexponential kinetics.
(13) Two glycolipids were isolated from pig brain and were shown to be the fatty acid esters of kerasin and cerebron in which the second fatty acid moiety is attached to the 6-position of the galactose.
Nitrogenous
Definition:
(a.) Of, pertaining to, or resembling, nitrogen; as, a nitrogenous principle; nitrogenous compounds.
Example Sentences:
(1) These results are discussed in relation to the possible existence of enzyme-bound intermediates of nitrogen fixation.
(2) The measurement of the intestinal metabolism of the nitrogen moiety of glutamic acid has been investigated by oral ingestion of l-[15N]glutamic acid and sampling of arterialized blood.
(3) The induction of cells with two Y chromosomes by nitrogen mustard (NM) was examined.
(4) The disappearance of the herbicide, Avadex (40% diallate), from five agricultural soils (differing in either pH, carbon content, or nitrogen content), incubated under sterile and non-sterile conditions, was followed for a period of 20 weeks.
(5) Suspensions of isolated insect flight muscle thick filaments were embedded in layers of vitreous ice and visualized in the electron microscope under liquid nitrogen conditions.
(6) Airway closure (CV), functional residual capacity (FRC) and the distribution of inspired gas (nitrogen washout delay percentage, NWOD %) and arterial oxygen tension (PaO2) was measured by standard electrodes in eight extremely obese patients before and after weight loss (mean weights 142 and 94 kg, respectively) following intestinal shunt operation.
(7) Formula fed infants retained more nitrogen and gained weight faster.
(8) Triglyceride (Trigly) in female dogs, glutamic-pyruvic transaminase (GPT) and urea nitrogen (Urea-N) in male dogs tended to increase.
(9) Nitrogen retention was curvilinear in relation to metabolic live weight (kg0.75) in both series.
(10) Corynebacterium parvum-treated mice produce large amounts of circulating nitrogen oxides and develop a severe liver injury in response to lipopolysaccharide (LPS).
(11) Eight men and eight women each performed peak oxygen intake tests on a cycle ergometer breathing ambient air and a mixture of 12% oxygen in nitrogen (equivalent to an altitude of 4400 m) in the two experiments.
(12) From this, it was suggested that a negligible amount of oestradiol was released from these compounds and that the oestradiol moiety was useful as a carrier for the nitrogen mustard moiety.
(13) The intravenous administration of ovine placental lactogen to pregnant and non-pregnant sheep produced significant acute decreases in plasma free fatty acid, glucose and amino nitrogen concentrations.
(14) In contrast, nitrogen incubation did not alter the basal levels of TBA reactants except for a small rise associated with VE deficiency.
(15) MCT TPN was found to have some disadvantages, especially with regard to nitrogen balance and plasma albumin levels.
(16) Nitrogen mustard (N2M) treatment of rabbits induced neutropenia, and, in ligated ileal loops, it inhibited fluid secretion induced by salmonella or by cholera toxin (CT).
(17) For dipeptides containing the amino terminal residues glycine, alanine and phenylalanine, abstraction of the hydrogen from the carbon adjacent to the peptide nitrogen was the major process leading to the spin-adducts.
(18) The raw data are obtained by capillary gas chromatography using a nitrogen-phosphorus detector.
(19) Total protein, RNA, DNA, nitrogen, free amino acids and water content were determined in both lymphatic organs.
(20) This is the first evidence supporting carbon-nitrogen bond formation as the initial site of interaction between the two substrate molecules.
