Physical Science Quarter 1 – Module 4: The Chemistry of Life (Biomolecules)

This module was created to help and give you an idea of the concepts behind the four macromolecules: carbohydrates, lipids, nucleic acids, and proteins. Since these molecules primarily constitute a living organism, they are also called biomolecules.

The module will focus on discussing the general structure and functions of biomolecules, as well as the common samples or material where they could be seen.

The learners are also expected to:

(a) explain how the structures of biological macromolecules, such as carbohydrates, lipids, nucleic acid, and proteins, determine their properties and functions (S11/12PS-IIIe-22)

After going through this module, you are expected to:

1. Identify the four macromolecules according to their general structure;

2. Describe the properties of each macromolecule; and

3. Explain the functions of each macromolecule, as well as the common samples where it can be seen.
