2. Illustrate the main ways of synthesising and degrading fatty acids,
triglycerides and major complex lipids
3. Know how triglycerides are accumulated and used
4. Illustrate cholesterol metabolism and its regulation
5. Explain the mechanisms by which lipids are conveyed in different districts body's body
Metabolism of amino acids

5. Know the peculiarity of the metabolism of different tissues:
a. liver (including the production of bile pigments and metabolism ethanol)
b. fatty tissue
c. blood (including the transport of gases, plasma proteins, blood pathological haemoglobins, iron homeostasis, mechanisms
of production and elimination of free radicals and clotting)

2. Evaluate energy demands in different physiological situations (basal and functional metabolism)
3. Indicate the characteristics of an appropriate diet and analyse its role in maintaining of homeostasis
4. Explain the biological role of essential nutrients
Biochemical indicators of integrated functions
1. Explain the biochemical basis of blood sugar homeostasis
