乙醛

But you do not forget that half of the Chinese people with the mutation of aldehyde dehydrogenase.

可您别忘了，中国人一半带有突变的乙醛脱氢酶。

Even worse is this: aldehyde dehydrogenase basically relying on this to digest.

更要命的是：乙醛基本上靠这个脱氢酶来消化掉。

However, this study should be noted that: the Chinese people in the United States, half of the normal aldehyde dehydrogenase carriers.

但这个研究有一点需要指出：在美国的中国人也有一半是正常的乙醛脱氢酶携带者。

So, when you determine that they are carriers of mutations in aldehyde dehydrogenase, you should beware of coronary heart disease and diabetes.

所以，当你确定自己是突变的乙醛脱氢酶携带者，你还要当心冠心病和糖尿病。

To be successful, a crucial selectivity problem in the conversion of aldehyde 4 to aldol 3 had to be understood and solved.

要取得成功，关键选择性问题转化为乙醛醛34已被理解和解决。

The nucleophilic attack step of a classical Aldol reaction was studied using acetaldehyde anion and formaldehyde as reactants.

采用乙醛负离子和甲醛作为反应物，对经典的醛醇缩合反应中的亲核进攻步骤进行了研究。

Allantoin was synthesized from glyoxylic ,and urea,which the mixed acid was used as catalyst.

以乙醛酸和尿素为原料，混酸作催化剂合成了尿囊素。

In the course of oxidation, reaction temperature should rise step by step, and in the late stage, reduced pressure distillation should follow so that the concertration of gly oxalic acid can rise and production rate of allantoin can rise up to 40%.

在氧化反应的过程中逐步地提高反应温度，反应后期进行减压浓缩，提高了乙醛酸的浓度，缩短了氧化时间，并使尿囊素産率达到40%。

The results also indicated a low production of acetic acid, acetoin and ethyl acetate, and high amounts of amyl alcohols in all of the ciders.

结果在所有萍果汁也表明了乙酸、乙醛和乙酸乙酯的低产量和大量产生的戊基乙醇。

The results showed that the main product was benzaldehyde and a little by-products were styrene oxide and phenylacetaldehyde.

发现该工艺中主要生成苯甲醛，少量副产物是环氧苯乙烷和苯乙醛等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
