PSC208 Plant Metabolism (8)

Plant Metabolism is a subject which investigates plant and yeast biosynthetic and catabolic processes. The subject compares and contrasts plant and yeast metabolism, and considers in detail those processes that influence the biosynthesis of flavour, colour and aroma compounds of economic importance, particularly in grape and wine production.

Learning Outcomes

Upon successful completion of this subject, students should:
  • be able to describe the roles of carbohydrates and carbohydrate metabolism in plants and yeasts
  • be able to describe the role of amino acids in plant and yeast metabolism and explain their importance in the formation of flavour and aroma compounds of economic importance.
  • be able to use knowledge of protein structure and function to explain the role of enzymes in plant and yeast metabolism
  • be able to describe the roles of different classes of lipids involved in plant and yeast metabolism and explain their role in forming economically important flavour and aroma compounds and their influence on berry properties and yeast fermentation
  • be able to describe plant secondary metabolite processes and the unique contribution of these metabolites in grape and wine production

Syllabus

This subject will cover the following topics:
  • Introduction to plant and yeast metabolism
  • Carbohydrates and carbohydrate metabolism in plants - Carbohydrate classification and optical isomerism; biologically important monosaccharides and disaccharides; structural and storage homopolysaccharides with cellulose and starch as examples
  • Amino acid metabolism in plants: amino acid synthesis; assimilation of inorganic nitrogen; transport amino acids; aromatic amino acid synthesis
  • Proteins and protein metabolism in plants - primary, secondary, tertiary and quaternary structures; role of enzymes as biological catalysts; simple enzyme kinetics; the regulation and control of enzyme-catalysed reaction rates in yeast and plant metabolism
  • Lipid metabolism in plants: fatty acid biosynthesis; synthesis of membrane lipids; synthesis and catabolism of storage lipids; lipids as secondary product precursors
  • Secondary metabolites of economic importance including: phenolics, lignins, terpenoids, carotenoids, thiol conjugates (cysteine, glutathione), methoxypyrazines; the biosynthesis of colour, flavour and aroma compounds influencing berry development and grape maturation
