    請(qǐng)問(wèn)我的這個(gè)有什么語(yǔ)法錯(cuò)誤嗎?幫忙改正下,
    the primary structure of XG contains pentameric repeat units which was formed by two D-glucose,two D-mannose and one D-glucuronic acid.
    Approximately onehalf of the terminals D-mannose contain a pyruvic acid residue linked via keto group to the 4 and 6 positions.這個(gè)句子有什么語(yǔ)法錯(cuò)誤嗎?

    優(yōu)質(zhì)解答
    稍作改動(dòng):
    the primary structure of XG contains pentameric repeating units which are formed by two D-glucose,two D-mannose and one D-glucuronic acid
    或者
    the primary structure of XG contains pentameric repeating units formed by two D-glucose,two D-mannose and one D-glucuronic acid
     
    repeat units 是專(zhuān)業(yè)術(shù)語(yǔ)嗎?如果不是,建議改成上面建議的形式
    units which are formed 中的時(shí)態(tài)無(wú)需過(guò)去時(shí).which are 可以省略
