二聚体

When a multisubunit complex is activated at the plasma membrane, one of its subunits is released.

通常的产物是同源二聚体，但有时也会是异源二聚体。

They had suppressed the cathodic process of carbon steel electrode. Their inhibition performance was also related with their molecule stereo conformation and electron configuration. Four of bis-(1, 1'-benzotriazoly)-α,β-diamide compounds linked via-CO 〓CO-chain were synthesized and certified by IR and 〓H-NMR. The minimum energy conformations of these compounds were obtained by MM2 forcefield program. The two benzotriazole moiety in BBT1 was more planar than in other compounds. This was beneficial in increasing the inhibition effects of BBT1. In 0.5M H〓SO〓 solution, BBT1 suppressed anodic corrosion reaction. In 3%NaCl solution, BBT1 suppressed both cathodic and anodic corrosion reactions. 1- [ (1'-imidazolly)-methyl] benzotriazole was synthesized by Mannich reaction.

合成了四个通过-CO〓CO-连接的双（1，1'-苯并三唑）-α，ω-二酰胺化合物，采用MM2分子力学程序优化了它们的分子结构，双（1，1'-苯并三唑）-α，ω-二酰胺化合物的缓蚀作用与其分子内两个苯并三唑单元的空间取向有关系，良好的平面性有利于苯并三唑二聚体的吸附和缓蚀作用，苯并三唑二聚体BBT1分子内两个苯并三唑单元近似平行，所以显示出较好的缓蚀效果。0.5M硫酸中BBT1主要抑制铜的阳极溶解的电化学反应；3％NaCl溶液中，BBT1对铜的阳极溶解和氧的阴极还原过程均有抑制作用，相比较而言对阴极过程的抑制作用更大一些。

It is shown that the methanol dimer and methanol cluster are the predominant species of methanol in gaseousness. So we believe that rather the methanol dimer is the original reactant of the methanol dehydration reaction to dimethyl ether than the mono-methanol.

研究表明，在气相中，甲醇分子主要以二聚体和多聚体的形式存在，据此提出甲醇脱水反应的原始反应物是甲醇二聚体，而不是单个甲醇分子。

The oligomerization of isoprene with titanium tetrachloride as catalyst and alkylaluminium chlorides as promotor was studied, and especially the effects of the reaction conditions on the synthetic activity and selectivity of dimer and trimer were investigated in detail.

研究了以四氯化钛为主催化剂，以烷基铝为助催化剂催化异戊二烯的低聚反应，详细考察了各种反应条件对催化合成二聚体及三聚体的活性和选择性的影响。

In order to mimic this repair process of apoenzyme, we synthesized two model compounds, in which tryptophan and/or tyrosine was covalently linked to cyclobutane thymine dimer, and measured the splitting quantum yield of dimer under 295 nm light. By investigating the photosensitized splitting properties of the dimer, some new insights into the intramolecular electron-transfer process were gained.

为了模拟酶蛋白的这一修复过程，合成了色氨酸和/或酪氨酸与胸腺嘧啶二聚体共价连接的化合物，作为酶-底物复合物的模型，研究了它们在295 nm光照射下氨基酸残基光敏化二聚体裂解的性质，测定了二聚体裂解量子产率，获得一些新的结果并对其进行了分析。

SDS-PAGE showed that fusion proteins had a disulfide-bonded dimeric structure and existed as homodimer.

SDS-PAGE结果显示该蛋白具有通过二硫键结合的二聚体结构并以同源二聚体的形式存在。

The chain scission occurs at the position with respect to double bonds, forming the main products including dipentene, styrene and vinyicyclohexene.

二聚体形成途径主要有两种：（1）主链自由基进行分子内转移，&反咬&实现环化，生成二聚体；（2）单体通过双分子合成反应生成二聚体。

In present study, we demonstrated that μ opioid receptor and D1 dopamine receptor could form heteromeric complexes in membranes preparation from HEK293T cells transiently cotransfected with both receptors and from mice striatum.

在本工作中，我们通过免疫共沉淀和BRET法证明，HEK293T细胞上瞬时表达的μ阿片受体和D1多巴胺受体能形成异源二聚体，并证实μ阿片受体和D1多巴胺受体异源二聚体存在于小鼠纹状体中。

The reaction of [60] fullerene with dimethyl malonate and diethyl malonate in the presence of manganese acetate dihydrate for 20 min afforded singly bonded [60] fullerene dimers in a 1, 4-addition pattern.

Mn作为一类良好的自由基引发剂，能有效地催化C〓与丙二酸二甲酯和丙二酸二乙酯的自由基加成反应，生成C〓的二聚体。在回流的氯苯中随着时间的的延长，二聚体分解成1，4-双加成的C〓衍生物。

The dimerization is thermodynamically unfavorable by the enthalpy. However, the formations of trimers and tetramers are very favorable thermodynamically even at high (1200 K) temperatures. Comparisons of the thermodynamic parameters of subsequent oligomerization are also given.

由焓变可知，单体形成二聚体在热力学上是不利的，而形成三聚体和四聚体在高达1200 K的温度下是有利的，同时分析比较了后续反应的热力学参数。
