Therefore, the metabolic pathway from soybean oil to erythromycin was presumed as follows: soybean oil is metabolized into TCA pathway to generate much α ketoglutaric acid and then generate succinyl CoA by strengthening TCA pathway, and the methylmalonyl CoA is formed from succinyl CoA by isomerization. Finally, methylmalonyl CoA can be used as the precursor for the biosynthesis of erythromycin.

推测豆油经过红色糖多孢菌代谢后进入红霉素合成的一条可能途径：豆油经过代谢后进入TCA循环，并强化了TCA循环的通量，产生了大量α酮戊二酸，再生成琥珀酰CoA，琥珀酰CoA在甲基丙二酰CoA异构酶的作用下生成甲基丙二酰CoA作为红霉素合成的前体。

This study was based on the soy protein isolates as raw materials. Chemical modification( acetylation,succinylation ,phosphorylation and urea modification) of SPI were used to improve adhesive strength and water resistance of SPI-based plywood adhesives. Then two modified ways combined were applied to SPI and their adhesive properties were studied. This research also characterized the thermal and adhesive properties of two major soy protein components 7S conglycinin and 11S glycinin after urea modification. Finally, the mechanism of improving SPI's adhesive properties was preliminarily discussed.

本文是以大豆分离蛋白为原料，进行SPI的化学修饰以提高其胶粘特性；采用了磷酸化试剂三聚磷酸钠、乙酰化试剂乙酸酐、琥珀酰化试剂琥珀酸酐和有机溶剂尿素修饰和变性SPI，研究修饰和变性后的SPI作为木材胶粘剂的胶粘性与耐水性，同时研究了两种方法复合修饰SPI对其粘度、胶粘强度和耐水性的影响；然后以SPI为原料，进行7S和11S球蛋白的提取以及胶粘特性的研究，对SPI起胶粘特性的机理进行了初步探讨。
