Biochemistry
The main biomolecules of the organism: sugars, aminoacids, lipids, cholesterol, energy molecules. Reserve molecules, glycogen and triglycerides.
Proteins: peptide bond, aminoacidic sequence, three-dimensional structure (eg collagen); post-translational modifications, phosphorylations, glycosilations, proteolysis, bonds with coenzymes
Oxygen transporters: Hemoglobin / Myoglobin
Enzymes: properties, kinetics, inhibitions, regulation, specificity, nomenclature, hints of enzyme co-factors.
Vitamins.
Metabolism: anabolism and catabolism, bonds and regulations; bioenergetics: ATP- phosphorylation at the substrate level and NAD + / FAD-reducing power
Respiratory chain.
Glycolysis, glycogen metabolism and effect of insulin and glucagon.
Krebs cycle, gluconeogenesis and their regulation.
Nitrogen metabolism, transamination, transamination, urea cycle and uric acid.
