Classified under:
Hypernyms ("acceptor" is a kind of...):
drawee (the person (or bank) who is expected to pay a check or draft when it is presented for payment)
Sense 2
Meaning:
(chemistry) in the formation of a coordinate bond it is the compound to which electrons are donated
Classified under:
Hypernyms ("acceptor" is a kind of...):
chemical compound; compound ((chemistry) a substance formed by chemical union of two or more elements or ingredients in definite proportion by weight)
Domain category:
chemical science; chemistry (the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions)
Context examples:
Alkyltransferases and Aryltransferases are classes of enzymes that transfer an alkyl or aryl chemical group from one compound (the donor) to another compound (the acceptor).
(Alkyltransferase and Aryltransferase, NCI Thesaurus)
Usually the alkalinizing agent(s) acts as a proton acceptor, neutralizing the acidity of a biologic environment (skin, gastric content, urine, etc.) and raising the pH.
(Alkalinizing Agent Preparation, NCI Thesaurus)
Oxygen is the final electron acceptor at the end of the chain, resulting in the production of water.
(Electron Transport Pathway, NCI Thesaurus/BIOCARTA)
The CYP2D6*11 allele exhibits a clinically-relevant SNP (g.883G>C) that eliminates the splice acceptor site of intron 1 and results in a premature stop codon.
(CYP2D6*11 Allele, NCI Thesaurus)
Enzymes catalyzing the transfer of fucose from a nucleoside diphosphate fucose to an acceptor molecule which is frequently another carbohydrate, a glycoprotein, or a glycolipid molecule.
(Fucosyltransferase, NLM, Medical Subject Headings)
Natural or synthetic compounds or mixtures, Antiacid Preparations such as sodium bicarbonate, sodium citrate, and phosphate salts act as proton acceptors, neutralizing the acidity of a biologic environment (skin, gastric content, urine, etc.) and raising the pH.
(Antacid Preparation, NCI Thesaurus)
Azithromycin reversibly binds to the 50S ribosomal subunit of the 70S ribosome of sensitive microorganisms, thereby inhibiting the translocation step of protein synthesis, wherein a newly synthesized peptidyl tRNA molecule moves from the acceptor site on the ribosome to the peptidyl (donor) site, and consequently inhibiting RNA-dependent protein synthesis leading to cell growth inhibition and cell death.
(Azithromycin, NCI Thesaurus)
A class of enzymes that catalyze the reaction of glutathione with an acceptor molecule (an arene oxide) to form an S-substituted glutathione; a key step in detoxification of many substances; start of the mercapturic acid pathway.
(glutathione S-transferase, NCI Thesaurus)
Cyclooxygenase Interaction involves temporary non-covalent binding, typically through intermolecular physical forces of attraction and spatial complementarity, between a molecular entity and Cyclooxygenase, an enzyme complex that catalyzes the formation of prostaglandins from unsaturated fatty acid, molecular oxygen, and a reduced acceptor.
(Cyclooxygenase Interaction, NCI Thesaurus)
Encoded by human EEF2 Gene (EF-G/EF-2 Family), highly conserved 857-aa 95-kDa cytoplasmic Elongation Factor 2 is essential for protein synthesis and required for GTP-dependent ribosomal A-site to P-site translocation of nascent protein chains: peptidyl-tRNA is moved from the ribosome acceptor site to the next mRNA codon by hydrolysis of GTP bound to EF2.
