Definition of sulphonate in English: sulphonate(also sulfonate) nounˈsʌlfəneɪt Chemistry A salt or ester of a sulphonic acid. Example sentencesExamples - Thus, small organic molecule 3-propane sulfonate, one of the agents to improve the recovery of membrane proteins, was used as the template to induce the bR molecules to be self-assembled in the processing.
- Metal ions may form insoluble complexes with the sulfonate groups of the dye, thus reducing the amount of available dye, while calcium interferes with interactions between cellulose and the dye.
- Because the salts of these ions and the alkane sulfonates and alkyl hydrogen sulfates are largely water soluble, the detergent remains dispersed in the water.
- The sulfonate groups on each molecule are likely to stand on opposite directions to reduce repulsion.
- This strain is characterized by its ability to utilize an exceptionally broad range of organosulphur compounds as the sole sulphur source during in vitro growth, including many aromatic and aliphatic sulphonates and sulphate esters.
verbˈsʌlfəneɪt [with object]Chemistry Convert (a compound) into a sulphonate, typically by reaction with sulphuric acid. these sulphonated cross-linked polystyrene resin beads are now used in all softening plants Example sentencesExamples - This short summary demonstrates the diversity of substrates used by SOT proteins in addition to the identical co-substrate PAPS, and the broad spectrum of physiological processes where sulphonated compounds are involved.
- Some examples of neutral electrophiles are ozone, Lewis acids, sulfonating agents, halogenating agents, and peracids.
- Amino acid analyses were carried out by ion exchange chromatography on sulphonated polystyrene resin linked to divinyl benzene.
- Grubb built a prototype cell, using a sulphonated polystyrene resin similar to that used in water softeners, and patented the idea in 1955.
- Either a sulfonated Alcian blue stain or Congo red stain was used in the initial evaluation for amyloidosis.
Derivatives noun Chemistry Meng et al. have investigated meso-substituted porphyrins, synthesized by sulfonation or methylation of the phenyl or pyridyl groups, respectively. Example sentencesExamples - The degree of sulfonation was ascertained by means of chromatography.
- The existence of several dimer species is not surprising given the presence of monosubstituted and disubstituted monomers plus isomers with different positions of sulfonation of the phthalocyanine nucleus.
- The common characteristics of flavonol SOTs are as follows: they all do not use divalent cations for sulphonation, they have a similar mass of 35 kDa, and the active form of these enzymes is a monomer.
- In contrast, phase II metabolism, including acetylation, sulfonation, conjugation, and glucuronidation, is little changed with aging.
