Answer» Solution :(i) Starch CONSISTS of two parts amylose and amylopectin. Amylosein a polymerof `alpha` - D- glucoseunitsheld by`C_(1)- C_(4)`glycosidiclinkage . Amylopectin is a polymer of `alpha`- D - glucose unitsheld be `C_(1) - C_(4)` glycosidiclinkage andbrancing OCCURS by `C_(1) - C_(6)` glycosidiclinkages. Cellulose in a polymer of `beta` - D- glucose unitsheld by `C_(1)`of oneunit and `C_(4)` of next unit. (ii) Linkagein nucleicacids isphosphodiester linkage. (iii) EXAMPLEOF fibrousprotein : Kertain. Exampleof globularprotein: Albumin . |
