L-Phenylalanine is an organic compound with a molecular formula of C9H11NO2 and a molecular weight of 165.19. It is a white crystalline powder. It is mainly used in biochemical research, preparation of culture medium, and nutritional research.
Applications
Medicine
L-phenylalanine is a physiologically active aromatic amino acid, one of the essential amino acids that cannot be synthesized naturally by humans and animals, and is an important component of compound amino acid infusions; Intermediates of amino acid anticancer drugs such as sarcoma, thyroxine and melanin; studies have shown that L-phenylalanine can be used as a carrier of anticancer drugs to directly introduce drug molecules into cancer areas , and its effect is 3 to 5 times that of other amino acids. This can not only inhibit the growth of cancer tumors, but also reduce the side effects of drugs.
Food
For food, it can be added to baked food to strengthen the nutritional effect of phenylalanine, and also undergo amino-carboxylation reaction with sugars to improve food aroma, and supplement the amino acid balance of functional food required by the human body;
L-phenylalanine is the main raw material for the production of new health-care sweetener aspartame. Aspartame is an A-level safety food additive identified by the World Health Organization (WHO) and Food and Agriculture Organization (FAO) expert committees. It has been approved for use by more than 120 countries and regional governments. It has pure sweetness and high sweetness. Its sweetness is 200 times that of sucrose, and its calorific value is less than 1/200. It is the most ideal sweetener for people with high blood pressure, heart disease and diabetes, but it is not suitable for people with phenylketonuria.
Impact
When phenylalanine is deficient, it can affect the synthesis of tyrosine in the body, leading to a decrease in the level of thyroxine and affecting its metabolic activity. If there is a lack of phenylalanine hydroxylase, the reaction of oxidation to tyrosine is hindered, which can lead to phenylketonuria, which is the most common amino acid metabolism defect.
