Protein is an important component that makes up all the cells and tissues of the human body. Protein is required for all important components of the body. In general, protein accounts for about 18% of the total body mass, and the most important thing is that it is related to life phenomena.

Protein is the material basis of life, is an organic macromolecule, is the basic organic matter that constitutes cells, and is the main bearer of life activities. Without protein, there is no life. Amino acids are the basic building blocks of proteins. It is a substance that is closely linked to life and to various forms of life. Protein is involved in every cell and all important components in the body. Protein accounts for 16% to 20% of the body's weight, that is, a 60kg adult has about 9.6~12kg of protein in the body. There are many kinds of proteins in the human body, and their properties and functions are different. However, they are composed of more than 20 amino acids in different proportions, and are continuously metabolized and renewed in the body.

Protein is a substance having a certain spatial structure formed by twisting a polypeptide chain composed of an amino acid in an "dehydration condensation" manner.
Proteins must contain carbon, hydrogen, oxygen, and nitrogen.

Protein is a polymer compound in which a-amino acids are combined in a certain order to form a polypeptide chain, and then one or more polypeptide chains are combined in a specific manner. Protein is the scaffold and main substance that constitutes the tissues and organs of the human body. It plays an important role in human life activities. It can be said that there is no life activity without protein. The protein in the daily diet is mainly found in lean meat, eggs, beans and fish.


Antibody is a large Y-shaped protein secreted by plasma cells (effector B cells) and used by the immune system to identify and neutralize foreign substances such as bacteria, viruses, etc., and is found only in body fluids such as blood of vertebrates, and On the cell membrane surface of its B cells, antibodies can recognize a unique feature of a particular foreign object called the antigen.

Antibodies are a class of immunoglobulins that specifically bind to an antigen. The antibody is classified into a lectin, a statin, an antitoxin, a lysin, an opsonin, a neutralizing antibody, a complement-binding antibody, and the like according to the reaction form thereof. The antibodies are classified into normal antibodies , such as anti-A and anti-B antibodies in the blood type ABO type, and immunological antibodies such as anti-microbial antibodies. According to the source of the reactive antigen, it is divided into a heterologous antibody, a heterophilic antibody, an alloantibody and an autoantibody. According to the agglutination state of the antigen reaction, it is divided into a complete antibody IgM, an incomplete antibody IgG, and the like.

Antibodies are widely used in medical practice. For the prevention, diagnosis and treatment of diseases have a certain role. Clinically, gamma globulin is used to prevent viral hepatitis, measles, rubella, etc. Internationally, anti-Rh immunoglobulin is used to prevent hemolysis caused by Rh blood group incompatibility. Diagnosis such as rheumatoid factor for rheumatoid arthritis, anti-nuclear antibody (ANA), anti-DNA antibody for systemic lupus erythematosus, anti-sperm antibody for diagnosis of primary infertility, etc.; Antitoxic treatment for poisoning and treatment of immunodeficiency diseases.
