Summary Introduction
To review:
The presence of several hydrogen bonds and the strong structure in the given Figure 1, representing the linear structure of cellulose after referring to its molecular structure shown in Figure 2.
Figure 2: Molecular structure of cellulose
Figure 1: Linear structure of cellulose
Introduction:
Cellulose forms an important component of the plant cell walls. The cellulose protein is present in abundance on the earth. It is the polysaccharide, which is composed of the glucose. The glucose units found in the cellulose are majorly linked by the beta-glycosidic linkages unlike in glycogen and starch, where these units are found linked by alpha-glycosidic linkage.

- In the structure in the picture, the monosaccharide units (alpha-D-galactopyranosyl and beta-D-allopyranose) are linked via alpha-1->3 glycosidic bond. Then, the formed disaccharide units are linked via beta-1->4 glycosidic bond. Then, an Oligosaccharide is formed which has 10 monosaccharide units, meaning that it contains 5 disaccharide units.

Provide two reasons for your answer.arrow_forwardWhy do think nucleotides are also sometimes referred to as “bases” or “nucleotide bases”? What is the difference between a nucleotide and a nucleoside? Explain by giving an example, using structures. What kind of bond links a base to some sugar? Is the sugar an alpha or beta anomer? In what position(s) of the sugar does this occur? In what position(s) of the base does this occur? Instead of the term “Formation of a nucleoside”, what could the name of the reaction be? What functional group is being formed? Define the primary structure of DNA/RNA.
