The molecular formula of L-tryptophan: C11H12N2O2, white to yellow-white crystal or crystalline powder. Odorless or slightly odorless, coloring after prolonged exposure. It is more stable when heated with acid in the dark. It is easily decomposed when coexisting with other amino acids, sugars and aldehydes.

　　White crystalline flakes or crystalline powder. Slightly bitter. Odorless. The sublimation temperature is 168-170℃. It is an essential amino acid and is necessary for the normal development of infants and the nitrogen balance of adults. There are four isomers, and only the L-form has physiological effects. Excessive consumption will have an antagonistic effect with leucine and hinder development. Adult men need 1.3g/100ml.

　　Colorless needle-like or flaky crystals, which soften at 277°C and decompose at 287°C. The solubility in water at 25°C is 41.9g/L, very slightly soluble in alcohol, insoluble in ether and chloroform. Sweet.

　　Vitamin B2 (chemical formula: C17H20N4O6, formula weight 376.37) is also called riboflavin, slightly soluble in water, and stable when heated in neutral or acidic solutions. It is a component of the prosthetic group of yellow enzymes in the body (yellow enzymes play a role of hydrogen transfer in biological redox). When lacking, it will affect the body's biological oxidation and cause metabolic disorders. Most of the lesions are inflammation of the mouth, eyes and external genitals, such as angular cheilitis, cheilitis, glossitis, conjunctivitis and scrotum, so this product can be used for the prevention and treatment of the above diseases. The storage of vitamin B2 in the body is very limited, so it must be provided by the diet every day.

　　Cytosine, the scientific name is 2-carbonyl-4-aminopyrimidine, the CAS number is 71-30-7, and the molecular formula is C4H5N3O. One of the main base components in nucleic acids (DNA and RNA). Cytosine can be synthesized from dimercaptouracil, concentrated ammonia and chloroacetic acid as raw materials. Used as a drug intermediate.

　　The abbreviation for Glutataione, and there is a noun to explain GSH. Melitin GSH is a special substance for detoxification. It is a small molecule peptide composed of three amino acids. It acts as an important antioxidant and free radical scavenger in the body, such as combining with free radicals, heavy metals, etc., thereby reducing the body The harmful poison is transformed into harmless substances and excreted from the body

　　Adenosine Cyclophosphate, also known as cyclic adenosine phosphate and adenosine cyclophosphate, is a white crystalline powder chemical. The chemical name is adenosine-3',5'-cyclic phosphate (cAMP), the molecular formula is C10H12N5O6P, the molecular weight is 329.20600, and the melting point is 260°C. Adenosine cyclophosphate is an anti-angina pectoris drug. It is mainly used clinically for the adjuvant treatment of angina and acute myocardial infarction, but its duration of action is short

　　Vitamin B4 (Vitamin B4; Adenine) is the old name for adenine, which is no longer regarded as a real vitamin, and is no longer a member of vitamin B. Molecular formula: C5H5N5 Molecular weight: 135.127 Its properties are: white needle-like crystals. It begins to sublime at 220°C and decomposes at 360-365°C. Soluble in acid and alkali, slightly soluble in alcohol, insoluble in ether and chloroform. The aqueous solution is neutral. Has a strong salty taste. It is obtained by ammoniating 4,6-dichloro-5-nitropyrimidine with ammonia to obtain 4,6-diamino-5-nitropyrimidine, which is then cyclized with formic acid, formamide and sodium thiosulfate. Mainly used to participate in the synthesis of DNA and RNA, for leukopenia caused by radiotherapy, benzene poisoning and anti-tumor, for acute neutropenia, medicine and biochemical research
