同构体

Isomerism is very important because enzyme specificity restricts viable organisms to the use of only one of the two forms.

异构现象是非常重要的，因为酶的特异性限制生物体都只能使用两种同分异构体中的一种。

Because the components of isomerization products are complex and the boiling points of mostly isomers are similar, separation of mesitylene is extremely difficult and give low yield.

由于异构化生产均三甲苯的产物组成比较复杂，多为同分异构体，许多组分的沸点非常相近，分离十分困难，且产品纯度低。

The 3-D finite element model of thoracolumbar spine was established based on the CT value of an aged volunteer using software Ansys-5. 0.The stress field and motion diagram of the thoracolumbar spine were evaluated, especially the change of that of augmented L〓 vertebral body with TCP-PMMA cement.

Monosaccharide Isomerization Simple aldoses and ketoses containing the same number of carbon atoms are isomers of each other; that is, a hexose and a hexulose both have the empirical formula (C6 H1206 )and can be interconverted by isomerization.

单糖异构化含有相同数目碳原子的单醛糖和酮糖互为同分异构体，也就是说一个已醛糖和一个已酮糖都符合经验分子式C6 H1206，并且可通过异构化作用相互转化

There are some isomeric compounds of hydroxypyridinone. The compounds of 2-hydroxy-6-pyridinone have been used to dyestuff and pesticide widely. The compounds of 3-hydroxy-2-pyridinone and 3-hydroxy-4-pyridinone are paid attention to, because they are very useful heavy metal chelations. Especially, they are wonderful candidate medicament for the toxicosis of depleted uranium, so they can settle the DU jeopardize to the people.

羟基吡啶酮化合物有不同的同分异构体，2-羟基-6-吡啶酮已被广泛用于染料和农药行业，而3-羟基-2-吡啶酮和3-羟基-4-吡啶酮也引起了人们的重视，因为这两种异构体的化合物是非常理想的重金属络合剂，尤其重要的是，它可作为解决贫铀中毒的候选药物，有望解决战争中由于贫铀中毒带来的危害。
