生物素

With its unique molecular structure and outstanding bio-activities, qinghaosu has been proven as a worthy subject for in-depth studies with profound influence, not only for pharmacy, but also for phytochemistry, biogenetic synthesis and organic synthetic chemistry, chemical biology, etc. A great amount of work has been done in the last 30 years, with a lot more issues to be explored. Researchers need to seize the opportunity and make more achievements.

青蒿素以其独特的分子结构和杰出的生物活性显示出它是一有深远影响的研究对象，不仅对于药学，而且对于植物化学、生源合成、有机合成化学、化学生物学等学科都是一个可以大有作为的课题。30年来国内外已做了不少工作，但是还有更多的问题有待探索，机不可失，时不再来，期待着在綻放青蒿素的故土上结出更多的果实。

In recent years,with the development of genetic engineering technology,people hope through biological engineering to product defesin.

In this paper,the effect of horseradish peroxidase on the biosynthesis of artemisinin was studied.

通过细胞提取液，在体外条件下研究了辣根过氧化物酶对青蒿素生物合成的影响。

Brown rot fungi thus stand out as an exception to the usually valid observation that lignocellulose must be delignified first if organisms are to gain access to plant cell wall polysaccharides.

以往如果生物要进入植物细胞壁的多糖组织，必先使木质纤维素发生脱木素反应，因此在这点上，棕腐真菌是个特例。

Thus, insect is potentially an abundant resource for alternative raw material of chitin in the future.

昆虫是当今地球上未被利用的最大生物资源，特别是昆虫的甲壳素资源尚未开发。

OBJECTIVE: To observe the antagonism effects of both alcohol and ethyl acetate extracts, monomer CA-1201 three components from Chinese herb Cissus assamica on endothelin-1 (ET-1) biological responses in vivo and in vitro.

目的：观察红背丝绸2种提取物和单体(CA-1201)对内皮素-1(endothelin-1，ET-1)生物效应的拮抗作用。

This paper briefly introduced the toxicity, the biosynthetic pathway, and the relative standards of citrinin in monascus.

本文概述了红曲桔霉素的毒性、生物合成途径及相关标准。

In order to optimize an effective combined preservative applied to the orange juice preservation, the authors studied the synergistic effect of biological and chemical combined preservative which contained Nisin, potassium sorbate, EDTA and sodium isoascorbate in preservation of orange juice compared to preservation effect of each aforementioned additive in individual use. Results show that the growth of microorganisms can not be inhibited completely using each aforementioned additive in single use.
