BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Starch is the most important source of carbohydrates in the human diet and accounts for more than 50% of our carbohydrate intake. It occurs in plants in the form of granules, and these are particularly abundant in seeds (especially the cereal grains) and tubers, where they serve as a storage form of carbohydrates.

Detailed explanation-2: -The most common carbohydrate polymers that are found in nature are cellulose, starch, dextrins and cyclodextrins, chitin and chitosan, hyaluronic acid, and various gums (carrageenan, xanthan, etc.).

Detailed explanation-3: -The polymers of carbohydrates are disaccharides and polysaccharides that consist of two or more monomers respectively. Examples of monosaccharide are: glucose, fructose and galactose. Examples of disaccharides are: sucrose, lactose and maltose.

Detailed explanation-4: -Starchy foods are our main source of carbohydrate and have an important role in a healthy diet. Starchy foods – such as potatoes, bread, rice, pasta, and cereals – should make up just over a third of the food you eat, as shown by the Eatwell Guide.

Detailed explanation-5: -Assertion :Starch is a polymer of glucose. Reason: Starch is a reserve food of plants and has two components (i) amylose-a branched polymer of glucose (ii) amylopectin-an unbranched polymer of glucose.
