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.

　　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.

　　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
