Proteins – Structure, Functions, Classification / Biomolecules / CSS Chemistry Lec 4

This lecture provides a comprehensive explanation of Proteins, one of the most essential biomolecules in biology and chemistry. Designed for CSS Chemistry Paper 2, PMS, and other competitive exams, this video is also ideal for FSc, BS, MSc Chemistry, and Biochemistry students aiming for conceptual clarity and exam success.

We will explore the structural complexity of proteins from primary to quaternary levels, understand how their amino acid sequences determine biological function, and discuss their role in enzymatic activity, cell structure, transport, and immunity.

What You Will Learn in This Lecture:

Definition and importance of proteins in living organisms

Amino acid composition and peptide bond formation

Levels of protein structure: primary, secondary, tertiary, quaternary

Examples of fibrous and globular proteins

Protein classification based on composition and function

Structure–function relationship in proteins

Role of proteins in enzymes, hormones, and antibodies

Denaturation and its biological implications

Proteins in CSS/PMS Chemistry and university-level exams

By the end of this lecture, you will have a solid understanding of protein chemistry — essential for mastering biochemistry topics and performing well in both academic and competitive exams.
