Question

Name three natural polynomials and write where they are found and from which monomer they are made.

Answer 1

Cellulose, a structural polysaccharide in plant cell walls, wood, and cotton; monomer: β‑glucose. Starch is a plant storage polysaccharide in seeds, tubers, and grains; monomer: α‑glucose. Proteins found throughout animals and plants (muscles, hair, enzymes, skin, eggs); monomers: α‑amino acids. These natural macromolecules provide support, energy storage, and biological function, are synthesised by polymerisation reactions, and form the basis of tissues, nutrition, and heredity in all kingdoms of life.
