Exempel på hur du använder DEPROTONATED i en mening

• It contains an α-amino group (which is in the protonated − form under biological conditions), a carboxyl group (which is in the deprotonated − form under biological conditions), and a side chain consisting of a hydroxymethyl group, classifying it as a polar amino acid.
• In approximately neutral aqueous solution (pH ≅ 7), the basic amino group is mostly protonated and the carboxylic acid is mostly deprotonated, so that the predominant species is the zwitterion.
• The peptide backbone also provides donor groups; these include deprotonated amides and the amide carbonyl oxygen centers.
• The nonionized phenolphthalein molecule is colorless and the double deprotonated phenolphthalein ion is fuchsia.
• The protonated form of bromothymol blue has its peak absorption at 427 nm thus transmitting yellow light in acidic solutions, while the deprotonated form has its peak absorption at 602 nm thus transmitting blue light in more basic solutions.
• Here ethyl propiolate is deprotonated by n-butyllithium to give the corresponding lithium acetylide.
• Indazole is an amphoteric molecule which can be protonated to an indazolium cation or deprotonated to an indazolate anion.
• Once the Schiff base linkage is formed, holding the PLP molecule in the active site, the phosphate group on the PLP readily donates a proton to an inorganic phosphate molecule, allowing the inorganic phosphate to in turn be deprotonated by the oxygen forming the α-1,4 glycosidic linkage.
• To complete the reaction, the serine and histidine residues reverse their original catalytic actions: the histidine, now basic, abstracts a proton from water, priming it as a nucleophile to attack at C2, and the protonated serine is deprotonated by the cis-aconitate double bond to complete the hydration, producing isocitrate.
• The resulting β-nitro alkoxide is protonated by the conjugate acid of the base that originally deprotonated the nitroalkyl structure, giving the respective β-nitro alcohol as product.
• A solution's pH can also greatly affect surface charge because functional groups present on the surface of particles can often contain oxygen or nitrogen, two atoms which can be protonated or deprotonated to become charged.
• Because the dihydroisoquinoline nitrogen is basic, neutralization is necessary to obtain the deprotonated product.
• Each asymmetric unit cell making up the crystal contains six chroman molecules of which two are deprotonated and two protonated morpholine molecules.
• Under these conditions, the sulfonate groups are fully deprotonated and the mediator exists as a dianion.
• It is important that the second proton comes from Asp96 since its deprotonated state is unstable and rapidly reprotonated with a proton from the cytosol.
• A collective switch of hydrogen bond orientations may contribute to the directionality of proton flux as His37 is dynamically protonated and deprotonated in the conduction cycle.
• Two ketyl groups react in a coupling reaction yielding a vicinal diol with both hydroxyl groups deprotonated.
• The Aldol product is then deprotonated forming another enolate followed by the elimination of water in an E1cB dehydration reaction.
• Chloroform (1) is deprotonated by a strong base (normally hydroxide) to form the chloroform carbanion (2) which will quickly alpha-eliminate to give dichlorocarbene (3); this is the principal reactive species.
• Compared to the salts of their deprotonated forms (a class of compounds known as the oxyanions), oxyacids are generally less stable, and many of them only exist formally as hypothetical species, or only exist in solution and cannot be isolated in pure form.
