一般描述

α;-含 α-1,4-葡聚糖-1,6-交联；每 25 个葡萄糖单位一个末端组

应用

支链淀粉是一种以葡萄糖为基础的高度支链多糖，它与直链淀粉共同形成淀粉。支链淀粉的糖苷键为 α-葡聚糖链中的 α- 1,4 和分支点的α-1，6。玉米中的支链淀粉在结构上与其他植物中的支链淀粉不同，可用于淀粉发育的研究。

φ,β-Limit dextrins of domains and clusters of sweetpotato amylopectin were subjected to extensive hydrolysis by Bacillus amyloliquefaciens α-amylase to release building blocks and reveal the internal structures of clusters. The composition of building blocks was analyzed by size-fractionation, gel permeation

Questions

1–2 of 2 Questions  

  1. I want to know how many monomers compose one polymer in average.

    1 answer

    1. Unfortunately, the average molecular weight of this product is not determined, therefore the number of monomeric subunits comprising the polymer cannot be estimated.

      Helpful?

  2. what is the molecular weight of amylopectin from maize?

    1 answer

    1. The molecular weight of this product has not been determined. However, a number of references suggest a molecular weight of 828.7.
