Unit Code: BCH511

Unit Name: Introduction to Biochemistry

Description: The purpose of this course is to provide you with an understanding of chemical processes and molecules that occur within living organisms. Biochemistry investigates the structure, composition, and function of biomolecules, such as proteins, carbohydrates, lipids, and nucleic acids, and how they interact within biological systems. Biochemistry plays a central role in understanding the molecular basis of life and has applications in various fields, including medicine, biotechnology, agriculture, and environmental science. It provides insights into disease mechanisms, drug development, and the design of novel therapeutics. Key concepts include Macromolecules including proteins, carbohydrates, lipids, and nucleic acids. Macromolecules are built from smaller subunits and play vital roles in the structure, function, and regulation of cells.Proteins are complex macromolecules made up of amino acids. They serve various functions in living organisms, including enzymatic catalysis, structural support, transportation, and signaling. Carbohydrates are sugars and their polymers. They provide energy to cells and are essential for cellular processes. Examples include glucose, cellulose, and glycogen. Lipids are diverse molecules that are non polar e.g. fats, oils, phospholipids, and steroids. Lipids serve as energy storage, structural components of cell membranes, and signaling molecules. Nucleic acids, such as DNA and RNA, are polymers of nucleotides. They carry genetic information and are involved in protein synthesis, gene expression, and the transmission of hereditary traits.Enzymes are biological catalysts that accelerate chemical reactions within cells by lowering the activation energy required for the reaction to occur. They are crucial for maintaining metabolic pathways and regulating cellular processes. A solid understanding of biochemistry is crucial for dieticians to effectively assess nutritional needs, formulate evidence-based dietary recommendations, and promote health and well-being through proper nutrition.
