Interpretation:
Concept introduction:
Fatty acids are aliphatic mono-carboxylic acids that are mostly obtained from the hydrolysis of natural fats and oils. They have a general formula
Triacylglycerols may be composed of three identical fatty acid chains or from two or three different fatty acids.

- Explain the mechanism by which beta-oxidation of fatty acids is controlled.arrow_forwardExplain why insulin is required for adipocytes to synthesize triacylglycerols from fatty acids.arrow_forwardWhy are the essential fatty acid associated with low incidence of heart disease? Cite some clinical signs of essential fatty acid deficiency. Explain how aspirin can block the synthesis of prostaglandins?arrow_forward
- , which indicates AG for each glycolytic reac- tion under intracellular conditions. Assume that glyceraldehyde-3- phosphate dehydrogenase was inhibited with iodoacetic acid. Which glycolytic intermediate would you expect to accumulate most rapidly, and why?arrow_forwardName the key enzymes of gluconeogenesis. Explain how lactate is converted to glucose.arrow_forwardRefer to Figure, which indicates ΔG for each glycolytic reaction under intracellular conditions. Assume that glyceraldehyde-3-phosphate dehydrogenase was inhibited with iodoacetate, which reacts with its active site cysteine sulfhydryl group. Which glycolytic intermediate would you expect to accumulate most rapidly, and why?arrow_forward
- Why are the enzymes α-Amylase and α-glucosidase active in a patient with hyperglycemia or diabetes? How do they become activated?arrow_forwardWhy would glutamate utilize the oxidative deamination pathway over transamination – especially if removal of NH4+ requires ATP? Would it not be favorable for the body to just use transamination?arrow_forwardPhosphoglucomutase is crucial for glycogen breakdown as well as for glycogen synthesis. Explain the role of this enzyme in each of the two processes.arrow_forward
- Given the statement on the image, which is/are true about fatty acid activation before beta oxidation?arrow_forwardexplain how α-tocopherol and ascorbate work together in suppressing the oxidation of polyunsaturated fatty acidsarrow_forwardIn the fasted state, FADH2 and NADH for oxidative phosphorylation are mainly provided by fatty acid oxidation. Explain how fatty acids are mobilised from adipose tissue by the action of glucagon.arrow_forward
