carboxylate

(kär-bŏk′sə-lāt′)
n.
A salt or ester of an organic acid, derived from the carboxyl group. Soaps, which are usually the sodium or potassium salts of fatty acids, are carboxylates.
adj. (-lāt′, -lĭt)
1. Of or relating to a carboxylate.
2. Of or relating to the anionic conjugate base of a carboxylic acid, specifically the CO22- group

car·box·y·late

(kahr-boksi-lāt)

DMPA is included in PU frame to enhance the water compatibility after complete deprotonation of the carboxyl group to a carboxylate ion using NaOH, as shown in Scheme 1.
Each two neighboring Mn2 form a binuclear unit via 2[[mu].sup.2] carboxylate brdiging oxygen (Mn2-O2= 2.174 [Angstrom]), the distance between the two Mn(II) ions is 3.42 [Angstrom], the binuclear units are connected together via O4 carboxylate oxygen (Mn2-N3= 2.318[Angstrom], Mn2-O1= 2.767[Angstrom], Mn2-O4=2.131[Angstrom], Mn2-O5= 2.075[Angstrom], Mn2-O7= 2.433[Angstrom]), to furnish a one dimensional binuclear chain (Figure 2.b).
To investigate this expectation, we synthesized 2 in-dole (FUB-PB-22, NM-2201) and 3 indazole (FUBNPB-22, 5F-NPB-22, 5F-SDB-005) carboxylate SCRAs that were commercially unavailable at the time.
Figure 1 shows the change in kappa number, viscosity, crystallinity, and carboxylate content for KBP when different pulp consistencies are used in the ozonation process.
Three positions in the basal plane are occupied by oxygen atoms of central carboxylate (Zn-O 2.101(2) [Angstrom]) and carbonyl (Zn-O 2.164 (3) [Angstrom]) groups as also the secondary amine nitrogen (Zn-N 2.122(2) [Angstrom]) of one lisinopril ligand, while the fourth is occupied by primary amine nitrogen (Zn-N 2.035(2) [Angstrom]) of a second lisinopril ligand.
These data clearly indicate that exchanging two chlorido ligands by a bidentate quinoline carboxylate group turns the unity cis-[Ru[(dppm).sub.2]] complex more cytotoxic, probably due to its higher solubility and disponibility in the culture medium.
Besides cysteic acid, also the presence of carboxylate ions in wool is important especially due to interactions with basic groups -NH2 and isoelectric point setting.
As indicated above, the carbon steel surface in the blank solution was initially covered with an air-formed oxide film which undergoes breakdown with increasing immersion time; when carboxylate is added to the chloride solution, it acts at local defects of the thin oxide layer sealing them according to the pore plugging concept [23].
In one study, the plasma concentration of oseltamivir carboxylate which is the active metabolite with administration of oseltamivir in intensive care patients was found to be 2 000-4 000-fold higher than 50% of the highest inhibitory level reported by Gubareva et al.
From the docking analysis of naphthofuran and benzofuran derivatives, it can be concluded that in most of the interactions nitro group formed hydrogen bond with Asp16, bromine atom, and carboxylate group showing hydrophobic interaction at the active site.
The two weak bands at 1579 and 1385 [cm.sup.-1] for PPA and 1606 [cm.sup.-1] and 1385 [cm.sup.-1] for POA are assigned to the asymmetric (-COO-as) and the symmetric (-COO-s) stretches of the carboxylate group, respectively.
"If PFOS and PFCAs can cross the blood-brain barrier in polar bears, it will also be the case in humans," Professor Rune Dietz of Aarhus University in Denmark (http://www.sciencedaily.com/releases/2013/07/130723081350.htm) said in a statement referring to two specific compounds, perfluorooctane sulfonate (PFOS) and perfluorinated carboxylate (PFCAs).
