Description
This component will provide students with the background required to appreciate the biochemical aspects of nutrition and the impact of nutrition-related factors on normal human biochemistry.  Areas covered include the digestion and absorption of nutrients, energy intake and expenditure, nutrition and metabolism of carbohydrate, cholesterol synthesis and homeostasis, metabolism of dietary fats and their effect on lipoprotein cholesterol, nitrogen metabolism, and minerals and vitamins and their roles in biochemical processes.

Learning Outcome
FNSC3030 contains six parts:
PART I      Energy and metabolism, intake and expenditure
PART II     Nutrition and metabolism of carbohydrates
PART III    Nutrition and metabolism of proteins
PART IV    Nutrition and metabolism of vitamins
PART V Nutrition and metabolism of fats
PART VI Metabolism of cholesterol and lipoproteins
The learning outcomes:
PART I      Energy intake, expenditure and metabolism Objectives:      After these lectures, a student should be able to
      describe changes in body composition from birth to adulthood.
    define the basal metabolic rate (BMR), resting metabolic rate (RMR), and diet-induced thermogenesis (DIT).
      describe the methods used in estimating BMR and RMR.
      calculate the energy content of a mixed diet
      identify the functions of brown fat tissue in energy metabolism.
      describe the role of carbohydrate in energy metabolism.
PART II     Nutrition and metabolism of carbohydrates Objectives: After these lectures, a student should be able to
      identify the mechanisms by which the plasma glucose level is regulated.
      define the glycemic index and explain how it is useful in the control of diabetes mellitus.
      outline the metabolic differences between glucose and fructose.
      describe the influences of dietary fructose on plasma LDL-cholesterol, HDL-cholesterol and triglyceride and explain the possible mechanisms involved.
      define insoluble and soluble fibers, and give some examples and source of each.
      identify the health effect of dietary fibers and explain the possible mechanisms involved.
      explain the biochemical basis of major inborn disorders of carbohydrate metabolism.
      list some major commercial artificial sweeteners and some specific characteristics of each.
PART III    Nutrition and metabolism of proteins
Objectives:      After these lectures, a student should be able to
      define the essential amino acids.
      define nitrogen balance and its application in the determination of protein requirement.
• identify the general steps by which amino acids are converted to glucose in fasting and starvation.
      explain the biochemical basis of homocystinuria and its atherogenic effect.
      explain the biochemical basis of phenylketonuria.
      describe the differences between animal and plant proteins.
      identify the positive and negative effects of vegetarian diets.
PART IV    Nutrition and metabolism of vitamins
Objectives:      After these lectures, a student should be able to
      describe the functions of fat-soluble vitamins.
• describe the structures and functions of B vitamins.
      define the term coenzymes and their role in energy metabolism.
      explain why some vitamins are essential to energy metabolism.
      describe some common biochemical tests to assess the vitamin status.
• describe the symptoms of various vitamin deficiency diseases.
PART V Nutrition and metabolism of fats
Objective: After these lectures, a student should be able to
  describe the nomenclature of lipids used in nutrition.
      describe the characteristics of omega-3, omega-6 and omega-9 fatty acids.
      identify the characteristic features of vegetable oils, fish oil and animal fats, and their potential nutritional significance.
identify the biochemical pathway by which linoleic acid is converted to arachidonic acid.
    identify the biochemical pathway by which -linolenic acid is converted to docosahexaenoic acid.
    identify the biochemical pathway by which oleic acid is converted to eicosatrienoic acid.
      list the chemical reactions and enzymes involved in chain-elongation and -desuration.
      identify the enzymes and biochemical pathway in fatty acid synthesis.
      understand the mechanisms by which dietary fatty acid composition affects lipogenesis.
      describe the possible health effects of trans fatty acids.
      list some common fat substitutes and the proposed use in food industry.
• explain why olestra is neither digested nor absorbed.
PART VI Nutrition and metabolism of cholesterol and lipoproteins
Objectives:      After these lectures, a student should be able to
      identify the major dietary factors influencing the level of plasma cholesterol.
      identify the biochemical pathway by which cholesterol is synthesized and degraded.
    describe the roles of cholesterol-7-hydroxylase and acyl CoA: cholesterol acyltransferase (ACAT) in metabolism of cholesterol.
    classify the inborn lipoprotein disorders.
    describe the processes by which cholesterol is digested, mobilized and transported in the body.
    define the hyperlipoproteinemia.
    understand the mechanism by which dietary plant sterols decrease the risk of atherosclerosis.
