Tyrosinase is a protein that is responsible for the characteristic color pattern of a Siamese cat.
Biochemistry is the study of the chemical processes in living organisms.
It deals with the structure and function of cellular components, such as proteins, carbohydrates, lipids, and nucleic acids. The behavior of these biomolecules underlies everything that occurs in living systems. Biochemistry helps us to understand systems from single-celled bacteria to complex organisms such as ourselves, and even the interactions of organisms in populations. Biochemistry integrates the molecular life sciences from the most basic biology-chemistry interface to molecular genetics and bioinformatics.
