2-Mercaptoethanol (also ß-mercaptoethanol, BME, 2BME, 2-ME or ß-met) is the chemical compound with the formula HOCH2CH2SH. ME or ßME, as it is commonly abbreviated, is used to reduce disulfide bonds and can act as a biological antioxidant by scavenging hydroxyl radicals (amongst others). It is widely used because the hydroxyl group confers solubility in water and lowers the volatility. Due to its diminished vapor pressure, its odor, while unpleasant, is less objectionable than related thiols.

2-Mercaptoethanol

2-Mercaptoethanol is one of the most common agents used for disulfide reduction. Sometimes referred to as ß-mercaptoethanol, it is a clear, colorless liquid with an extremely strong odor. All operations with this chemical should be performed in a well-ventilated fume hood. The reduction of protein disulfides with 2-mercaptoethanol proceeds rapidly via a two-step process involving an intermediate mixed disulfide. Due to its strong reducing properties, the reagent is used most often when complete disulfide reduction is required. It can also be used to cleave disulfide-containing crosslinking agents. Usually a concentration of 0.1-M 2-mercaptoethanol will cleave a disulfide-containing crosslinker and liberate conjugated proteins

Reducing proteins

Some proteins can be denatured by 2-mercaptoethanol, which cleaves the disulfide bonds that may form between thiol groups of cysteine residues. In the case of excess 2-mercaptoethanol, the following equilibrium is shifted to the right:

RS-SR + 2 HOCH2CH2SH ? 2 RSH + HOCH2CH2S-SCH2CH2OH
Reaction scheme for the cleavage of disulfide bonds by 2-mercaptoethanol
By breaking the S-S bonds, both the tertiary structure and the quaternary structure of some proteins can be disrupted.Because of its ability to disrupt the structure of proteins, it was used in the analysis of proteins, for instance, to ensure that a protein solution contains monomeric protein molecules, instead of disulfide linked dimers or higher order oligomers. However, since 2-mercaptoethanol forms adducts with free cysteines and is somewhat more toxic, dithiothreitol (DTT) is generally more used especially in SDS-PAGE. DTT is also a more powerful reducing agent with a redox potential (at pH 7) of -0.33 V, compared to -0.26 V for 2-mercaptoethanol.

Molecules of 2-mercaptoethanol (ME) were spontaneously chemisorbed on silver, copper, and gold surfaces. Surface-enhanced Raman scattering investigation revealed that, as for unsubstituted alkanethiols, the average orientation of the “molecular chain” of ME is the most perpendicular to the metal surface for ME molecules adsorbed on silver. Immersion of an ME-modified electrode in diluted ME solution leads to quick desorption of a portion of the monolayer and an increase in the relative surface concentration of the gauche conformer. The time constant of this rearrangement (below 1 min) is more than 1 order of magnitude shorter than that of monolayers formed from analogous thiols (HS-(CH2)2-X) with X = CH3, NH2, COOH, or SO3Na. The structure of the ME monolayer is highly pH-sensitive, but it is independent of the presence of neutral salts in solutions. In acidic solutions, the surface concentration of a gauche conformer considerably increases. Since protonation of a significant number of hydroxyl groups is unlikely under the conditions used, it is likely that in acidic solutions the kinetics of the desorption and the desorption/adsorption equilibrium are changed. It is probable that desorption of ME as thiol molecules is facilitated because some of the sulfur atoms of ME adsorbed as thiolate are protonated. We also found an analogous effect, although less pronounced, for monolayers self-assembled from propanethiol. This indicates that this mechanism, so far not considered, can also be important for some other (especially short-chain) thiols. In basic solutions, the concentration of a trans conformer increases and probably some of the hydroxyl groups dissociate. For all investigated solutions, the structure of the ME monolayer on gold was found to be less affected by its surroundings than that of monolayers on silver or copper.

2-Mercaptoethanol (also called Thioglycol) is a clear, colorless liquid with disagreeable odor.Beta mercaptoethanol is miscible in water and nearly all common organic solvents.Beta merkapto ethanol is used as a intermediate for the synthesis of PVC heat stabilizers and as a chain transfer agent in the manufacture of PVC. Beta mercapto ethanol is used as a building block to produce corp protection products, dispersants, fibers, textiles, .dyes, and pharmaceuticals. 2 Mercaptoethanol is used as a component of corrosion inhibitors and ore floatation agent. 2 mercaptoethyl alcohol is used in as a raw material for leather and fur industry, cosmetics, hair removal.

2-Mercaptoethanol is often used interchangeably with dithiothreitol (DTT) or the odorless tris(2-carboxyethyl)phosphine (TCEP) in biological applications

Güçlü indirgeme özelliklerinden dolay, reaktif tam disülfit indirgemesi gerektiinde en sk kullanlr. Disülfit içeren çapraz balama maddelerini ayrmak için de kullanlabilir. Genellikle bir 0.1-M2-merkaptoetanol konsantrasyonu bir disülfid içeren çapraz balaycy parçalayacak ve konjuge proteinleri serbest brakacaktr

Proteinleri azaltmak

Baz proteinler, sistein tortularnn tiyol gruplar arasnda oluabilen disülfür balarn parçalayan 2-merkaptoetanol ile denatüre edilebilir. Ar 2-merkaptoetanol durumunda, aadaki denge saa kaydrlr:

RS – SR + 2 HOCH2CH2SH? 2 RSH + HOCH2CH2S – SCH2CH2OH
Disülfit balarnn 2-merkaptoetanol ile parçalanmas için reaksiyon emas
SS balarn krarak hem üçüncül yap hem de baz proteinlerin kuaterner yaps bozulabilir. Proteinlerin yapsn bozma kabiliyetinden dolay, protein analizinde, örnein bir protein çözeltisinin kullanlmasn salamak için kullanlmtr. disülfit bal dimerler veya daha yüksek dereceli oligomerler yerine monomerik protein moleküllerini içerir. Bununla birlikte, 2-merkaptoetanol, serbest sisteinlerle katk maddesi oluturduundan ve bir miktar daha toksik olduundan, ditiyotreitol (DTT) genellikle özellikle SDS-PAGE’de kullanlr. DTT ayrca 2-merkaptoetanol için -0.26 V ile karlatrldnda -0.33 V’luk bir redoks potansiyeli olan (pH 7’de) daha güçlü bir indirgeyici maddedir.

2-merkaptoetanol (ME) molekülleri, gümü, bakr ve altn yüzeylerde kendiliinden kemorbe edildi. Yüzey arttrlm Raman saçlma aratrmas, ikame edilmemi alkanetillerde olduu gibi, ME’nin “moleküler zincirinin” ortalama yöneliminin, gümü üzerinde adsorbe edilen ME molekülleri için metal yüzeye en dik olduunu ortaya koydu. ME modifiyeli bir elektrotun seyreltilmi ME çözeltisine daldrlmas, tek tabakann bir ksmnn hzl bir ekilde desorpsiyonuna ve gauche konformerinin nispi yüzey konsantrasyonunda bir arta yol açar. Bu yeniden düzenlemenin zaman sabiti (1 dakikadan az), X = CH3, NH2, COOH veya S03Na ile benzer tiollerden (HS- (CH2) 2-X) oluturulan mono tabakalardan 1 kat daha büyüktür. ME tek tabakasnn yaps oldukça pH duyarldr, ancak çözeltilerdeki nötr tuzlarn varlndan bamszdr. Asidik çözeltilerde, bir gauche konformerinin yüzey konsantrasyonu önemli ölçüde artar. Önemli sayda hidroksil grubunun protonlanmas, kullanlan koullar altnda pek olas olmadndan, asidik çözeltilerde desorpsiyon kinetiinin ve desorpsiyon / adsorpsiyon dengesinin deimesi muhtemeldir. ME’nin tiyol molekülleri olarak desorpsiyonunun kolaylatrlmas muhtemeldir, çünkü ME’nin tiyolat olarak adsorbe edilen kükürt atomlarnn bazlar protonlanr. Propanetiolden kendiliinden monte edilmi tek tabakalar için, daha az belirgin olmasna ramen, benzer bir etki bulduk. Bu, u ana kadar düünülmeyen bu mekanizmann dier baz (özellikle ksa zincirli) tiyoller için de önemli olabileceini göstermektedir. Temel çözeltilerde, bir trans konformerinin konsantrasyonu artar ve muhtemelen baz hidroksil gruplarnn ayrr. Aratrlan tüm çözümler için, ME tek katmannn altn üzerindeki yapsnn, çevresi tarafndan gümü veya bakr üzerindeki tek katmanlardan daha az etkilendii bulundu.

2-Merkaptoetanol (ayrca Thioglycol olarak da bilinir), berrak, renksiz bir svdr ve kokusuzdur. Merkaptoetanol, suda ve neredeyse tüm genel organik çözücülerde karabilir. Merkapto etanol, PVC s stabilizatörlerinin sentezi için bir ara ürün olarak ve bir zincir olarak kullanlr. PVC üretiminde transfer maddesi. Beta merkapto etanol, koru koruma ürünleri, dispersanlar, lifler, tekstiller, boyalar ve farmasötikler üretmek için yap ta olarak kullanlr. 2 Merkaptoetanol, korozyon önleyicilerin ve cevher yüzdürme ajannn bir bileeni olarak kullanlr.
