ornithine

1 A colorless, foul - smelling ptomaine, NH 2 ( CH 2 ) 4 NH 2 , produced in decaying animal by the decarboxylation of ornithine.

腐胺一种无色, 恶臭的尸碱, NH2 ( CH2 ) 4NH2, 产生于腐烂的动物躯体中的鸟氨酸的脱羧作用.

2 The scarcity of ornithine aminotransferase in the kidney-yang deficiency rats resulted in deficient creatine phosphate which was need for depositing energy and most of ATP was consumed as heat energy.

但肾阳虚动物由于鸟氨酸氨基转移酶活性降低，导致储存能量的肌酸合成降低，使产生的ATP大部分通过热能形式消耗掉，从而导致肾阳虚的临床虚寒症状。

3 By using stable isotope tracers and analyzing gene expression, the researchers showed that S. gordonii releases a substance called ornithine that prompts F. nucleatum to produce more of a molecule called polyamine.

4 Lysine and ornithine have very similar molecular structures, and the authors found that Spe1, the enzyme that decarboxylates ornithine, can also decarboxylate lysine to generate cadaverine.

5 One possible way to explain this is if the core apoptotic machinery prevents ornithine from entering the mitochondrion and instead diverts it towards spermidine production.

6 On September 14, he was injected with the treatment, a normal ornithine transcarbamylase gene that the researchers had encased in an attenuated cold virus.

7 The enzyme ornithine transcarbamylase catalyzes a key step in the urea cycle and its deficiency can lead to accumulation of toxic levels of ammonia in the body.

8 General spirulina has no L-arginine, L-ornithine and little L-citrullin contained so as not to meet the needs of human health.

螺旋藻中不含有L -鸟氨酸和L -瓜氨酸，L -精氨酸的含量也极低，因而不能满足人体的某些特定的保健需要。

9 Large amount of cystine as well as arginine lysine and ornithine are excreted in the urine.

从患者的尿中排出大量的胱氨酸，精氨酸，赖氨酸和鸟氨酸。

10 Objective To clone human ornithine decarboxylase antizyme ( OAZ ) mutation gene and express its recombinant protein.

目的构建人鸟氨酸脱羧酶抗酶 ( OAZ ) 突变基因,重组至原核表达载体中并表达出重组蛋白.

11 Other diseases in which correcting a small percentage of cells might make a big difference include glycogen storage disease and ornithine transcarbamylase deficiency, an inherited disorder that causes ammonia to accumulate in the blood.

12 Objective To examine the function of ornithine decarboxylase antizyme inhibitor ( Oazin ) gene in the mouse development.

目的分析鸟氨酸脱 羧 酶抗酶抑制子基因在小鼠生长发育过程中的功能.

13 The precursors are two essential amino acids, argenine and ornithine and certain vitamins such as C and B 6.

14 At last, the magnification of preparation of the L-ornithine by enzymatic methods was studied simply, which provided the foundation for the factory production.

最后，对酶法制备L—鸟氨酸的放大生产进行初步探索，为工厂生产L—鸟氨酸提供依据。

15 The molecule urea is formed as a by-product of the conversion of arginine to ornithine.

16 Poly - L - Ornithine can change electric charge on the surface of protoplasts or foreign DNA.

本实验采用以多聚鸟氨酸改变外源DNA表面负电荷为正电荷的方法.

17 Tawfik and Metanis demonstrated that functional proteins could have come into being "from short and simple sequences" including an amino acid, ornithine, that does not exist in modern proteins.

18 Large amounts of cystine as well as arginine, lysine and ornithine are excreted.

大量的胱氨酸、精氨酸 、 赖氨酸和鸣氨酸被排出.

19 One of disorders he studied is known as OTC deficiency, short for ornithine transcarbamylase, a protein essential for pulling ammonia out of the bloodstream.

20 Hence, the urea cycle is also referred to as the ornithine cycle.
