作者认为,对氧化数的概念稍作调整,即可构成一个新的概念,不仅能定量标示有机物分子的还原态,而且是一个有用的生物能力学参数,姑且称之为碳还原数。一、联还原数的概念根据IUPAC对氧化数的定义,各种碳原子的氧化数如表1。氧化数虽也可用于比较不同有机分子的氧化态,但相加时正负数抵销,致使许多化合物的碳氧化数为0,如葡萄糖和乙酸均为0(图1)。欲扩大它的应用范围,必须设法消除负值。为此,作者建议以价 The author believes that a slight adjustment of the concept of oxidation number can constitute a new concept, which not only can quantitatively indicate the reduction state of organic molecules, but also is a useful bio-mechanical parameter, let’s call it carbon reduction number. First, the concept of the number of co-reduction According to the IUPAC definition of the number of oxidation, the oxidation number of various carbon atoms in Table 1. Although the oxidation number can also be used to compare the oxidation state of different organic molecules, but the addition of positive and negative offset, resulting in many compounds of carbon oxidation number 0, such as glucose and acetic acid are 0 (Figure 1). To expand its scope of application, we must try to eliminate negative values. To this end, the author suggested price
