Exempel på hur man kan använda THIOL i en mening

• The thiol is susceptible to oxidation to give the disulfide derivative cystine, which serves an important structural role in many proteins.
• The linkage is also called an SS-bond or sometimes a disulfide bridge and usually derived from two thiol groups.
• Other groups can also confer acidity, usually weakly: the thiol group –SH, the enol group, and the phenol group.
• Thiols are used as odorants to assist in the detection of natural gas (which in pure form is odorless), and the "smell of natural gas" is due to the smell of the thiol used as the odorant.
• MTs have the capacity to bind both physiological (such as zinc, copper, selenium) and xenobiotic (such as cadmium, mercury, silver, arsenic, lead) heavy metals through the thiol group of its cysteine residues, which represent nearly 30% of its constituent amino acid residues.
• Priming beta-ketosynthase in chemistry, a domain of polyketide synthases with a thiol group on a cysteine side-chain.
• Three examples of these reactions are the activity of coenzyme A (CoA) transferase, which transfers thiol esters, the action of N-acetyltransferase, which is part of the pathway that metabolizes tryptophan, and the regulation of pyruvate dehydrogenase (PDH), which converts pyruvate to acetyl CoA.
• The thiol moiety within the molecule has been associated with two significant adverse effects: the hapten or immune response.
• The thiol functional group of captopril was replaced with a carboxylic acid group, but additional modifications were required to achieve a potency similar to captopril.
• The initial transthioesterification step of the native chemical ligation reaction is catalyzed by thiol additives.
• Arsenic and some other heavy metals act by chelating with adjacent thiol residues on metabolic enzymes, creating a chelate complex that inhibits the affected enzyme's activity.
• There are many derivatives of the parent phthalocyanine, where either carbon atoms of the macrocycle are exchanged for nitrogen atoms or the peripheral hydrogen atoms are substituted by functional groups like halogens, hydroxyl, amine, alkyl, aryl, thiol, alkoxy and nitrosyl groups.
• At neutral pH, protein thiol groups specifically react with the functional groups methanethiosulfonate, maleimide, and iodoacetamide, creating a covalent bond with the amino acid Cys.
• Amifostine is an organic thiophosphate prodrug which is hydrolysed in vivo by alkaline phosphatase to the active cytoprotective thiol metabolite, WR-1065.
• Within weeks of the explosion, thiol (mercaptan, an odorous sulfur compound) was added to natural gas.
• ECD with UV-based activation increases the top-down MS sequence coverage of disulfide bond containing proteins and cleaves a disulfide bond homolytically to produce two separated thiol radicals.
• Pyrithione can be prepared in a two-step synthesis from 2-bromopyridine by oxidation to the N-oxide with a suitable peracid followed by substitution using sodium dithionite to introduce the thiol functional group.
• MCAT serves to transfer malonate from malonyl-CoA to the terminal thiol of holo-acyl carrier protein (ACP).
• This has also explained the need for a thiol reagent like beta mercaptoethanol in the regeneration of the protein since such reagents weaken the sulfhydryl bonds between cysteine residues, expediting the regeneration of the aequorin.
• Unsubstituted 1,2,4-triazole can be prepared from thiosemicarbazide by acylation with formic acid followed by cyclization of 1-formyl-3-thiosemicarbazide into 1,2,4-triazole-3(5)-thiol; oxidation of the thiol by nitric acid or hydrogen peroxide yields 1,2,4-triazole.
