Assignment Brief and Guidance
Task 1: Classify amino acids based on the functional groups.Identify D and L amino acid in the given structure below. Discuss its similarities and differences     Draw the structure and discuss about the R group of each amino acid listed below and calculate its pI value.ArginineHistidineProlineLeucineClassify the monosaccharides based on its functional group with its properties. Analyse the structure of Fisher projection of D- Glucose. Explain in detail about the steps involved in converting Fisher projection of D-Glucose to cyclic α- Pyranose as a Haworth projection.Identify the saturated and unsaturated fatty acids with examples. Compare and contrast the cis and trans fatty acids with its melting points.Discuss in detail about the chemical structure of DNA and RNA with its features. Explain the difference between nucleoside and nucleotide.
Task 2: Explain how the monomers joined together to form polymers like polysaccharides with its glyosidic bonds and structural features. Explain the role of the glyosidic OH group in the formation of monosaccharide cyclic structures and disaccharide α and β glyosidic links.Explain the formation of phospholipid bilayers and membrane bilayers from lipids and proteins using images.What are polypeptides? Explain the formation of peptide bond with neat illustrations and list out the catalyst used for the synthesis of peptide bond. Show different protein structures with its features.Analyse in detail how digestive enzymes breakdown biological macromolecules with examples.With all the above understanding analyse the importance of functional group and chemical attraction in determining the structure and properties of biological molecules like proteins, carbohydrates and membrane bilayer.
Task 3: You will be given range of powdered foods. Investigate by conducting appropriate test to identify whether each food contains carbohydrate/lipid/amino acids. Use your results to help you identify the presence of biomolecules in the food sample. Report the observation including Aim, principle, procedure, result, discussion, conclusion, and risk assessment.Do the experiment to find the optimum pH and temperature of an enzyme given.
Task 4: Define enzyme. Explain the structure, active site and its catalytic functions with its properties.What do you mean by enzyme inhibition and mention its types? Explain how enzymes combines to form metabolic pathway and inhibit it.Illustrate and explain the process and steps in glycolysis, acetyl COA formation and citric acid cycle.Define electron transport chain. Analyse the enzymes involved in cellular respiration with its reactions and highlight the key stages where ATP is produced and utilized. Calculate the total ATP synthesis via aerobic and anaerobic respirations linking the final yields of ATP with the glucose entered the glycolysis.
