Polymerisation a level biology
WebPolymers are the giant molecules formed by joining together of hundreds or thousands of smaller molecules. They belong to the category of macromolecules. The word polymer is derived from two Greek words; ‘poly’ meaning ‘many’, and ‘mer’ meaning ‘part’. Thus, a polymer is a large molecule made up of several identical repeating ... WebPolymers are made up of a combination of smaller molecules called monomers, through a process called polymerization. Carbohydrates are biological macromolecules made up of smaller molecules called …
