鸟嘌呤核苷

Guanosine A nucleoside present in DNA and RNA and consisting of guanine linked to D-ribose via a B-glycosidic bond.

鸟苷：是存在于 DNA 和 RNA 中的一种核苷，由鸟嘌呤通过 B 糖苷键连接 D —核糖所组成。

The cordyceps grass vegetable, the cordyceps grass is sour, the cordyceps grass many sugar, SOD—enzyme, guanin, urine, the gland... etc., a materials of the pit are all with the natural cordyceps grass homology, the poison reason evaluation:Have no poisonous side effect to the human body, is a stub in the world new species of biggest cordyceps grass in very unique body.

虫草素、虫草酸、虫草多糖、SoD、腺嘌岭、鸟嘌呤、尿嘧啶、腺苷等，核苷类物质都与天然虫草相同，毒理评价：对人体无任何毒副作用，是一株世界上绝无仅有形体最大的虫草新品种。

Nucleosides are compounds composed of a purine or pyrimidine base (usually adenine, cytosine, guanine, thymine, uracil) linked to either a ribose or a deoxyribose sugar.

核苷是由嘌呤基，嘧啶基(通常是腺嘌呤，胞嘧啶，鸟嘌呤，胸腺嘧啶，尿嘧啶)与核糖或脱氧核糖相连而组成的化合物。

After overcoming the flux shift during the process, the production ability of strains could be the limiting factor for further increasing the production. To avoid the random modification on strains, the comprehensive enzymatic study of nucleoside producing-pathway was conducted on four strains with different producing ability. And the results could be used to direct further reconstruction of strains. It was also found that nucleotidase was of much importance to nucleoside production.

在成功克服了代谢流的迁移之后，菌株的代谢能力可能成为了进一步提高产率的限制因素，为了避免对生产菌的进一步改造中的盲目性，对四株不同菌株间嘌呤途径关键酶活力的系统测定，对肌苷、鸟苷生产菌种的酶学特征有了全面的了解；并发现了核苷降解酶对于核苷生产能力至关重要；酶学特性研究对肌苷、鸟苷生产菌的进一步改造提供了方向。

I this is at that time, the opinion with peacockish true girl is full of in a heart.

这就是当时的我，一个心中布满虚荣的女孩子真实的想法。
