What's the difference between bibasic and dibasic?
Bibasic
Definition:
(a.) Having to hydrogen atoms which can be replaced by positive or basic atoms or radicals to form salts; -- said of acids. See Dibasic.
Example Sentences:
(1) Chest examination revealed the presence of bibasal coarse crepitations suggestive of aspiration.
(2) Radiographic changes consisted of bibasal (n = 2), right mid and lower (n = 2), or left basal consolidation (n = 1); there were no changes in seven episodes.
(3) We report an 87-year-old woman with idiopathic HES presenting with bibasal alveolar infiltrates.
Dibasic
Definition:
(a.) Having two acid hydrogen atoms capable of replacement by basic atoms or radicals, in forming salts; bibasic; -- said of acids, as oxalic or sulphuric acids. Cf. Diacid, Bibasic.
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) Lysine uptake is inhibited by other dibasic amino acids, arginine and ornithine but not cystine.
(3) Translation of the cDNA revealed a 138-amino acid precursor consisting of the Mas-DH amino acid sequence bounded by dibasic amino acid processing sites, a putative signal sequence, and additional peptide sequence on either side of the Mas-DH coding sequence.
(4) Chromatographic separation was accomplished under isocratic conditions using a reversed-phase C-18 analytical column and mobile phase consisting of equal parts of 75 mM dibasic ammonium phosphate buffer (adjusted to pH 3.5 with phosphoric acid) and acetonitrile, with a detection wavelength of 220 nm.
(5) In the present series of experiments we have used a combined kinetic and genetic approach to establish that dibasic amino acids are also asc substrates, systems asc1 and asc2 representing the only mediated routes of cationic amino acid transport in horse erythrocytes.
(6) The biosynthesized precursor contains hormone and neurophysin sequences linked by a Gly-Lys-Arg sequence and undergoes enzymatic processing reactions which include endoproteolytic cleavage at the Lys-Arg dibasic sequence, carboxypeptidase B-like exoproteolytic cleavage, and enzymatic amidation.
(7) 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.
(8) Maturation of pro-von Willebrand factor (vWF) to its active form requires proteolytic processing after a pair of dibasic amino acids (-LysArg-) at residue 763.
(9) From the deduced amino acid sequence, a biosynthetic pathway has been proposed that a prepro- form of porcine ET-1 is initially processed by dibasic pair proteolysis to a 39-amino acid intermediate form (big ET), which is then converted to ET-1 by specific proteolytic cleavage between Trp21 and Val22.
(10) Additional mitomycin admixtures were reconstituted with a buffer solution containing monobasic and dibasic sodium phosphate; these were diluted with 5% dextrose injection only.
(11) Lysine uptake is membrane potential sensitive and inhibitable by cystine, dibasic amino acids, and cycloleucine.
(12) The short form translation product should lack only an internal dibasic tetrapeptide.
(13) Esters of dibasic carboxylic acids show a minute but marked effect on the partition of proteins in general while malate and tartrate esters affect strongly the partition of chloroplast membranes.
(14) In addition to paired dibasic residues at the propeptide cleavage site, many proteins, including vWF, also contain an arginine at the P4 position.
(15) 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.
(16) Target compounds were made by treating N-(trifluoroacetyl)-14-halodaunorubicin (bromo or iodo) with monosodium salts of dibasic acids (malonic, succinic, glutaric, adipic, pimelic, azelaic, sebacic) in aqueous acetone.
(17) Lysobactin is a dibasic peptide with marked activity against Gram-positive aerobic and anaerobic bacteria.
(18) A small proportion of the VIP precursor followed a pathway in which the dibasic conversion site after PHM is not cleaved, as evidenced by the presence of a C-terminally extended form of PHM.
(19) These cultured cells, therefore, seem to be an excellent model system for the eventual elucidation of a) the inticacies of cystine metabolism and b) regulation of 1) the cystine-dibasic amino acid co-transporter system and 2) the development of the cysteine-glutamate anti-porter system.
(20) Lysine was reabsorped by a saturable transport system shared by the dibasics.
