Raw materials for pharmaceutical biology and biopharmaceuticals.

The raw materials of biopharmaceuticals are mainly natural biological materials, including microorganisms, human bodies, animals, plants and marine life. With the development of biotechnology, purposefully manufactured biological raw materials have become the main source of biopharmaceutical raw materials. Such as animal raw materials prepared by immunization, microorganisms prepared by changing gene structure or other cell raw materials. Biological drugs are characterized by high pharmacological activity, small side effects and high nutritional value. Biological drugs mainly include protein, nucleic acids, sugars, lipids and so on. These substances are composed of amino acids, nucleotides, monosaccharides and fatty acids. It is not only harmless to human body, but also an important nutrient.
