The invention relates to a method for preparing dimeric acid methyl ester and dimer acid thereof.

本发明是一种制备二聚酸甲酯及其二聚酸的制备方法，以不饱和脂肪酸甲酯含量较高的混合脂肪酸甲酯或混合脂肪酸为原料，浓硫酸为助催化剂，无水氯化铝或无水氯化锌为催化剂，采用两步催化法进行二聚化反应。

The front of the teahouse, a stand and sell acid Kok (I do not know what a tree node, the shape a bit like acacia, very acid, importers people Cuanmei), Shui date (end of the tree is, should be regarded as fruit, Zhuangrujizhua, a lump of a lump in some areas, that is called chicken Jiaozhao, taste Henguai, such as brown sugar, a bit like licorice) and the bubble pears sugar pears in the saline water, the pear flavor is equipped with, Kunming people Quepian in fresh and salt water within the bubble.

这家茶馆门前，有一个小摊，卖酸角(不知什么树上结的，形状有点像皂荚，极酸，入口使人攒眉)、拐枣(也是树上结的，应该算是果子，状如鸡爪，一疙瘩一疙瘩的，有的地方即叫做鸡脚爪，味道很怪，像红糖，又有点像甘草)和泡梨糖梨泡在盐水里，梨味本是酸甜的，昆明人却偏于盐水内泡而食之。

To optimize this artificial transcription factor, a nucleotide sequence coding for 12 glycins was introduced between GAL4 DBD and HIF-1α CAD and ODD domains by PCR. Glycin arm could separate these 2 domains and render them enough space to fold and exert better function.

为优化这一融合蛋白，在GAL4 DBD和HIF-1α转录激活结构域之间利用PCR方法引进一段编码12个甘氨酸的序列，试图通过甘氨酸臂使两个不同的结构域分别获得更有利表现活性的空间结构。

Our previous molecular cloning of snakehead fish GTH cDNAs revealed that the third cysteine residues is absent in shfFSH-β; instead, a positionally shifted cysteine is present at the N-terminus, as found in some phylogenetic related fish.

本研究已选殖鳢鱼脑下垂体GTH cDNAs，发现FSH-β次单元之第三个半胱胺酸并不存在，取而代之在N端有一多的半胱胺酸，由进一步资料分析发现鳢鱼相近鱼种亦有此特性。

For this, he has built a metabolic pathway in yeast cells that synthesises a chemical called artemisinic acid which chemists can easily convert into artemisinin.

为此，他在酵母细胞内建立代谢途径，从而可以将这种酵母细胞合成为一种叫做青蒿酸的化学成分，而化学家们可以很容易地将这种青蒿酸转化为青蒿素。
