This A-Level Biology course provides a detailed introduction to biological molecules, which are essential for all living organisms. It is designed for students following OCR, AQA, and Edexcel specifications and builds a strong foundation in molecular biology.
The course begins with an overview of biological molecules, explaining the difference between monomers and polymers and how large biological structures are formed. It then explores carbohydrates in detail, including monosaccharides, disaccharides, and polysaccharides such as starch, glycogen, cellulose, and chitin, highlighting their structure and biological roles.
Next, the course covers lipids, focusing on triglycerides and phospholipids, and explains their structure and function in energy storage and cell membranes.
Proteins are also studied in depth, including amino acid structure and the four levels of protein structure (primary, secondary, tertiary, and quaternary). The course also introduces globular and fibrous proteins and their different biological functions.
Additionally, learners will study key biochemical tests such as the Biuret test and emulsion test, used to identify proteins and lipids. The course also includes inorganic ions and their importance in biological systems. Finally, it explains the properties of water, including hydrogen bonding and its biological significance.
By the end of this course, students will have a solid understanding of biological molecules and their roles in life processes.
