Polymers and Biomolecules
Introduction
Polymers are large molecules composed of repeating units called monomers. Biomolecules are polymers found in living organisms, essential for their structure and function.
Basic Concepts
Monomers and Polymers
Monomers are small molecules that join together to form polymers. The linkages between monomers determine the polymer's properties.
Biopolymers
Biopolymers are polymers found in living organisms. They include proteins, nucleic acids, carbohydrates, and lipids. Each class has unique monomeric units and structures leading to diverse functions.
Equipment and Techniques
