Nutritional Biochemistry
Overview
This unit introduces many aspects of biochemistry related to macronutrient (carbohydrates, fats and proteins) and alcohol metabolism with an emphasis on human medical and nutritional applications of biochemistry. The unit will cover the biochemistry of digestion and metabolism of macromolecules in food and subsequent energy production; the understanding of key metabolic pathways underlying the utilization of nutrients for energy; the basis of nutrient requirements in various physiological states and nutrient control of gene expression. Practical components of measuring energy metabolism and understanding how dietary manipulation and metabolic hormones alters energy metabolism will be covered.

Learning outcomes
Students who successfully complete this unit will be able to:
- Describe various metabolic pathways of macronutrients and alcohol
- Evaluate and explain the role of nutrients in the optimal functioning of key biochemical pathways in the body
- Analyse the biochemical mechanisms of disease development and discuss therapeutic options
- Measure and investigate the physiological consequences of dietary and nutritional manipulation as they relate to essential metabolic pathways
- Explain the influence of diet and nutrition on intra- and extra-cellular signalling cascades, gene expression and how these have regulatory roles in metabolism
