What's the difference between butyric and butyrin?
Butyric
Definition:
(a.) Pertaining to, or derived from, butter.
Example Sentences:
(1) S-methyl-l-cysteine, 2-hydroxy-4-methiol butyric acid, S-adenosyl-l-methionine, and methionine peptides were the only compounds supporting growth, when substituted for methionine.
(2) We previously established that the binding constant (Ka) of this receptor site for the chemically synthesized model AGE, 2-(2-furoyl)-4(5)-(2-furanyl)-1H- imidazole-butyric acid (FFI-BA), on cells of the mouse macrophagelike cell line RAW 264.7 is identical to that for AGE proteins.
(3) 1H-NMR spectra of urine from a patient with propionic acidemia show peaks of 3-hydroxy-n-valerate, methylcitrate, propionyl glycine, 3-hydroxy-n-butyrate, lactate, 3-hydroxypropionate, tiglylglycine and hippurate.
(4) In the absence of n-butyrate, only a small percentage (approximately 4%) of the total beta A chromatin is in a soluble chromatin fraction following micrococcal nuclease digestion and centrifugation.
(5) Tumor cells were unreactive for alpha-naphthyl butyrate esterase (ANBE) and adenosine triphosphatase (ATP).
(6) Functional characteristics such as nitroblue-tetrazolium reduction, alpha-naphthyl butyrate esterase activity, and phagocytic capability occurred.
(7) Nanomolar concentrations of 1,25-dihydroxyvitamin D3 reduce the proliferation of RPMI 8226 cells significantly and simultaneously induce the appearance of both new properties and phenotype expression, such as butyrate esterase, enhanced expression of CD20 (B1), CD15 (Leu-M1) antigens and lambda chains, and decreased expression of the PC1 antigen using microfluorometric analysis.
(8) In the present study, we found that n-butyrate, a potent inhibitor of histone deacetylase, increases thyroid hormone receptor levels in three distinct non-pituitary cells without changing binding affinity.
(9) These observations demonstrate that brain cells synthesize a NGF mRNA in primary culture and that the butyrate moiety of db-cAMP enhances NGF gene expression in these cells, probably by a modification of chromatin structure in and around the NGF gene.
(10) In the presence of 1 mM sodium butyrate for 24 h, the cytoplasmic granules contained an abundant dense matrix.
(11) Both surfactants were extensively degraded in vivo to yield a common metabolite, butyric acid 4-[35S]sulphate, the major urinary radioactive component.
(12) Analysis of the end products showed an accumulation of ethyl alcohol in addition to butyrate and acetate, whereas, in the nonsporulating cultures, acetate and butyrate were the principal products.
(13) Benzoyltropine (30 microM) had no effect on the sodium-dependent uptake of norepinephrine, gamma-amino-butyric acid, glutamate or serotonin; tropacocaine (30 microM) inhibited only norepinephrine uptake at this concentration.
(14) In addition 6 further subjects were treated with 0.1% hydrocortisone-17-butyrate cream, a preparation considered to have little systemic action.
(15) The influence of sodium salt of butyric acid (C4H7NaO2) on the functional state of the cardiovascular system was studied on 12 guinea-pigs and 15 rabbits by the thermodilution method.
(16) For lactate+pyruvate as substrate, the stimulatory effect of butyrate was additive to that of 1muM-glucagon and for both lactate+pyruvate and fructose the stimulatory effect of butyrate was not influenced by 20nM-insulin.
(17) Infectious center assays demonstrated that the number of cells capable of producing HSV was increased as a result of butyrate pretreatment.
(18) These observations suggest that sodium butyrate induces a pattern of events leading to the differentiation of the rat insulinoma cells.
(19) We have analyzed the effect of sodium butyrate, under conditions which block the transition from G0 to S phase, on the steady-state levels of several cell growth-dependent mRNAs in ts13 cells, a G1-specific temperature sensitive mutant of the BHK cell line.
(20) This was done by measuring coronary sinus blood flow and arterial-coronary sinus differences of oxygen, glucose, free fatty acids, glycerol, lactate, beta-OH-butyrate, and amino acids in a similar group of 19 patients 4 to 5 hours after coronary operations.
Butyrin
Definition:
(n.) A butyrate of glycerin; a fat contained in small quantity in milk, which helps to give to butter its peculiar flavor.
Example Sentences:
(1) The in situ loop experiments showed that the absorption of dolichol from a triglyceride emulsion was dependent on the chain-length of the triglyceride; the absorption from a tri-n-butyrin emulsion in 1 h was 18.0% of the dose; and the absorption from an HCO-60 suspension was 4.3%.
(2) Lipolytic activity, determined in a medium containing 5% tri-n-butyrin, averaged 8.6 plus or minus .4 lipase units.
