To understand the architecture of the plant cell wall, it is of importance to understand both structural characteristics of cell wall polysaccharides and interactions between these polysaccharides. Interactions between polysaccharides were studied in the residue after water and chelating agent extraction by sequential extractions with H2O and alkali.

The 6 M alkali residue still represented 31%, 11% and 5% of all GalA present in carrot, tomato and strawberry, respectively, and these pectin populations were assumed to strongly interact with cellulose. Digestion of the carrot 6 M alkali residue by glucanases released ∼27% of the 6 M residue, mainly representing pectin. In tomato and strawberry alkali residues, glucanases were not able to release pectin populations. The ability of glucanases to release pectin populations suggests that the carrot cell wall contains unique, covalent interactions between pectin and cellulose.

果胶与纤维素在主要植物细胞壁中的相互作用

为了了解植物细胞壁的结构,重要的是了解细胞壁多糖的结构特征以及这些多糖之间的相互作用。研究了水和螯合剂萃取后残留物中多糖之间的相互作用,方法是依次用H 2 O和碱萃取。

6 M碱残渣仍然分别占胡萝卜,番茄和草莓中所有GalA的31%,11%和5%,并且假定这些果胶群体与纤维素强烈相互作用。葡聚糖酶对胡萝卜中的6 M碱残留物进行的消化释放了约6%的6 M残留物中的27%,主要代表果胶。在番茄和草莓的碱残留物中,葡聚糖酶不能释放果胶群体。葡聚糖酶释放果胶种群的能力表明,胡萝卜细胞壁在果胶和纤维素之间包含独特的共价相互作用。
