(i) Write the structural difference between starch and cellulose.
(ii) What type of linkage is present in Nuclei acids?
(iii) Give one example each for fibrous protein and globular protein.
(i) Starch is the mixture of two polysaccharides - amylose and amylopectin wheras cellulose is a linear polymer of in which C1 of one glucose unit and C4 of next are linked by glycosidic linkage.
(ii) Phosphodiester linkage is present in nuclei acids.
(iii) Examples:
Fibrous proteins - mysoin (in muscle)
Globular protein - insulin
