Biochemistry is the study of the chemicals and chemical processes in living organisms. It deals with the structure and function of cellular components, such as proteins, carbohydrates, lipids, nucleic acids, and other biological compounds.[1][2]
Macromolecules
Nucleic acid
Protein
Carbohydrate
Lipid
Metabolism
Energy
Glycolysis
Krebs cycle
Proteins
Urea cycle
Signal transduction
Signal transduction is the "intercellular or intracellular transfer of information (biological activation/inhibition) through a signal pathway".[3][4]
Intercellular primary messenger
Examples of primary messengers include hormones and neurotransmitters.
Hormone
Neurotransmitter
Cell surface receptor
Ion channel
Second messenger system
Examples of second messenger systems include the adenyl cyclase-cyclic AMP system, the phosphatidylinositol diphosphate-inositol triphosphate system, and the cyclic GMP system
