Iodine test used to detectA. ProteinB. FatC. CarbohydrateD. Chitin |
|
Answer» C. Carbohydrate The iodine test is used to detect C. carbohydrates. The iodine test is a qualitative test used to detect the presence of a polysaccharide called starch. The starch is made up of two units, amylose, and amylopectin. Amylose in starch is responsible for the formation of dark blue color with iodine solution. Amylose forms a helical structure and iodine slips inside this and forms deep blue color. Amylopectin has a linear structure and forms a reddish-purple color with iodine solution. |
