What's the difference between monobasic and triacid?

Monobasic


Definition:

  • (a.) Capable of being neutralized by a univalent base or basic radical; having but one acid hydrogen atom to be replaced; -- said of acids; as, acetic, nitric, and hydrochloric acids are monobasic.

Example Sentences:

  • (1) It is concluded that in this cell type (i) somatostatin-14 is exclusively generated by dibasic cleavage at the Arg-2-Lys-1 site of the intact precursor with concomitant production of prosomatostatin[1-76], and (ii) no direct interactions between the monobasic and dibasic processing domains occur.
  • (2) At 95 degrees C in the denatured form cytosine residues titrated as a simple monobasic acid of pK3.9 compared with pK approximately 2.5 for the native form at 25 degrees C. 2.
  • (3) These results demonstrate that AtT-20 cells efficiently and accurately process prodynorphin at both dibasic sites and monobasic cleavage sites, indicating that the AtT-20 cells contain enzymes capable of cleaving the precursor not only at dibasic residues but also at monobasic residues.
  • (4) Apurinic sites were introduced to dGpdG, dGpdT, dTpdG and pdGpdG by HCl hydrolysis and the cleavage of the phosphodiester bond was measured in the monobase dinucleotides by HPLC.
  • (5) Additional mitomycin admixtures were reconstituted with a buffer solution containing monobasic and dibasic sodium phosphate; these were diluted with 5% dextrose injection only.
  • (6) Comparison of amino acids around the monobasic cleavage sites suggests that these cleavages follow certain sequence motifs and can be described as the rules that govern monobasic cleavages: (i) a basic amino acid is present at either 3, 5, or 7 amino acids N-terminal to the cleavage site, (ii) hydrophobic aliphatic amino acids (leucine, isoleucine, valine, or methionine) are never present in the position C-terminal to the monobasic amino acid at the cleavage site, (iii) a cysteine is never present in the vicinity of the cleavage site, and (iv) an aromatic amino acid is never present at the position N-terminal to the monobasic amino acid at the cleavage site.
  • (7) From these results it can be concluded that both the "dibasic" cleavage between vasopressin and MSEL-neurophysin and the "monobasic" cleavage between MSEL-neurophysin and copeptin occur within the granule compartment.
  • (8) In fact, a monobasic cleavage requires two basic residues and a domain containing nonpolar amino acids such as alanine or leucine, or both.
  • (9) The basic extract was neutralized and analyzed on a phenyl column eluting with acetonitrile:10 mM potassium phosphate (30:70; monobasic, pH 5.6).
  • (10) The method is based on derivatization with the chiral reagent 2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl isothiocyanate (GITC), and resolution of the resulting diastereomeric thioureas by reversed-phase HPLC using methanol-aqueous monobasic ammonium phosphate mixture as the mobile phase.
  • (11) dibasic and monobasic specific forms, might explain the tissue-specific processing of precursors like the pro-opiomelanocortin and the CKK and somatostatin precursor.
  • (12) The most abundant of these were two 39 aa forms that resulted from the monobasic endoproteolytic cleavage of proHNP-1 and proHNP-3.
  • (13) The monobasic macrolide erythromycin on the other hand was less affected by the SC9252 mutation, less effectively antagonized by Mg2+, and was a far less effective permeabilizer than dibasic azithromycin.
  • (14) In the flounder the same dibasic residue processing site is utilised but cleavage at different monobasic sites takes place (corresponding to Arg50 and Arg97 in anglerfish preprosomatostatin II).
  • (15) Accordingly, we evaluated the buffering capacity of seven synthetic organic buffers and monobasic potassium phosphate, both singly and in pairs, over the pH range 7.4 to 6.0.
  • (16) It is concluded that the processing site in the intermediate form of the pancreatic eicosapeptide is an example of a proline-directed monobasic cleavage site that has been conserved during evolution.
  • (17) A liquid medium, designated as Kabatiella zeae medium (KZM), containing 10.0 g of carboxymethylcellulose, 5.0 g of maltose, 1.5 g of peptone, 1.0 g of monobasic potassium phosphate, 1 L of distilled water, is described.
  • (18) Both peptides are synthesized as larger precursors containing paired basic and monobasic amino acids at their processing sites, which, upon cleavage, generate either SRIF-14 or -28, respectively.
  • (19) The monobasic processing could also be distinguished from the dibasic cleavage mechanism as, in time, the cells gradually lost the ability to cleave at the monobasic site while the dibasic processing was unaffected.
  • (20) It was found that the sulfonamide ligands act as monobasic bidentate ON donors.

Triacid


Definition:

  • (a.) Capable of neutralizing three molecules of a monobasic acid or the equivalent; having three hydrogen atoms which may be acid radicals; -- said of certain bases; thus, glycerin is a triacid base.

Example Sentences:

  • (1) The present work suggests for the attention of cytologists an attempt at technical reconciliation of two methods, it obtained with a new coloration method that uses like fixative a cadmiumalcoholacetic mixture, like nuclear colouring the basic fuchsine maturing in presence of formic aldehyde and acetic acid, like cytoplasmatic colouring a triacid orange-eosine-blue mixture of aniline.
  • (2) On the basis of the three-dimensional structure of CheY which has an extensive sequence similarity with OmpR, three aspartic residues, D11, D12, and D55, of OmpR are considered to form a triacidic pocket serving as the phosphorylation center.
