trifluoroacetic acid (TFA) was applied to the binding site analysis of ester linkages between lignin and glucuronoxylan in Fagus crenata wood. Based on the conjugate acid DDQ-oxidation of a watersoluble lignin-carbohydrate complex (LCC-WE) from the beech wood, the frequency of the ester bonds between the lignin and glucuronic acid residue of glucuronoxylan was determined to be 1.6 per molecule of LCC-WE
摘要 苄基酯与 2,3-二氯-5,6-二氰基-1,4-苯醌 (DDQ) 和三氟乙酸 (TFA) 的共轭酸氧化应用于 Fagus 木质素和葡糖醛酸木聚糖之间酯键的结合位点分析克雷纳塔木。基于来自山毛榉木材的水溶性木质素 - 碳水化合物复合物 (LCC-WE) 的共轭酸 DDQ 氧化,木质素和葡糖醛酸木聚糖的葡糖醛酸残基之间的酯键频率被确定为每分子 LCC-1.6我们。
