BBCET-141 IGNOU Handwritten Assignment 2026-27

Course Scope & Syllabus Overview for BBCET-141: Nutritional Biochemistry

IGNOU’s BBCET-141: Nutritional Biochemistry is a core subject within the Bachelor of Science (Honours) in Biochemistry curriculum, designed to integrate biochemical principles with nutritional science. This course examines the biochemical foundations of nutrient metabolism, energy balance, and their physiological roles, bridging chemistry and human health. Students explore how macronutrients (carbohydrates, lipids, proteins) and micronutrients (vitamins, minerals) interact at the molecular level, addressing their absorption, storage, and metabolic pathways. The syllabus emphasizes evidence-based nutritional strategies, metabolic disorders, and the biochemical basis of dietary guidelines, ensuring graduates develop a rigorous understanding of nutrition’s biochemical underpinnings.

Key Syllabus Units & Topics

• Block-1: Introduction to Nutrition and Energy Metabolism: Covers fundamental concepts of nutrition, energy homeostasis, and the biochemical pathways of macronutrient catabolism, including glycolysis, the citric acid cycle, and oxidative phosphorylation.
• Block-2: Macronutrients in Health: Delves into the biochemical structure, digestion, and metabolic roles of carbohydrates, lipids, and proteins, with a focus on their physiological functions and implications in metabolic diseases.
• Block-3: Micronutrients in Health: Examines the biochemical functions of vitamins and minerals, including coenzyme roles, antioxidant mechanisms, and deficiencies like scurvy, rickets, and anemia.
• Block-4: Special Topics: Addresses emerging areas such as nutritional genomics, metabolic syndrome, and the biochemical basis of dietary supplements, integrating current research trends.
