Biomolecules

In this talk, the focus is Biomolecules, supported by coverage of the fundamental classes of biomolecules—proteins, carbohydrates, lipids, and nucleic acids—and examine their unique structures and essential roles in sustaining life. We will discuss how these molecules function as building blocks, energy sources, and information carriers within the cell. By understanding their interactions and integration, we gain insight into the molecular basis of cellular processes and the unity of biochemistry. This exploration highlights the importance of biomolecules in health, biotechnology, and our broader understanding of living systems.. Let us explore the fascinating world of biomolecules. Biomolecules are the chemicals of life, essential to every organism’s structure and function. Present in every cell, they act as both building blocks and machinery for life’s processes. The main types are proteins, carbohydrates, lipids, and nucleic acids. Each group is distinct, but all work together to support growth, maintenance, and metabolism. By studying these molecules, we discover how cells function, how energy flows through living systems, and how life is regulated at the molecular level. Proteins are complex biomolecules composed of long chains of twenty standard amino acids linked by peptide bonds. They form specific three-dimensional shapes—coils, sheets, folded globules, and multi-subunit assemblies —crucial for their function. Proteins act as enzymes,
