Apolysaccharide of unknown structure was isolated, subjected to exhaustive methylation, and hydrolyzed. analysis of the products revealed three methylated sugars: 2,3,4-tri-o-methyl-d-glucose, 2,4-di-o-methyl-dglucose, and 2,3,4,6-tetra-o-methyl-d-glucose, in the ratio 20: 1: 1. what is the structure of the polysaccharide?

Cellulose

Explanation:

Cellulose is best fit. The glucose in cellulose has hydroxyl group quite common at C2, C3, and C6 which makes it optimum candidate for this question.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
