3 month agoWhat is L-leucine?
L-leucine, with the chemical formula C6H13NO2, is a white and shiny hexahedral crystal or powdery substance with a slightly bitter taste. As one of the eight essential amino acids for the human body, it is not only a basic building block for protein synthesis, but also participates in regulating various physiological functions of the human body. L-leucine has good solubility and can be dissolved in water, acetic acid, dilute hydrochloric acid, alkaline solution and carbonate solution, slightly soluble in alcohol, and insoluble in ether. With its unique chemical structure and biological activity, L-leucine has broad application potential in many fields such as medicine, food, feed and agriculture.

Functions and Applications:
Food additives: L-leucine can be used as a food additive and nutritional supplement, with flavoring, preservative and antioxidant effects. It is often added to foods such as bread and pasta to improve the nutritional value of the food. It also has a certain preservative effect and can extend the shelf life of the food.
Pharmaceutical raw materials: In the pharmaceutical field, L-leucine is used to prepare amino acid infusions and comprehensive amino acid preparations. It is suitable for the treatment of diseases such as glucose metabolism disorders, liver disease, anemia, poisoning, muscular dystrophy, neuritis and mental illness. It can also be used for the diagnosis and treatment of idiopathic hyperglycemia in young children.
Sports Nutrition: Due to its remarkable effects in promoting muscle growth and repair, it is often added to protein supplements, energy drinks and functional foods to help athletes and fitness enthusiasts improve performance and speed up recovery.
Cosmetics materials: In cosmetics, L-leucine has the effects of moisturizing and promoting skin repair. It can help improve skin conditions, contains anti-aging and anti-wrinkle ingredients, can delay skin aging, and is often used in anti-aging and repair cosmetics.

Introduction |
L-leucine is an important amino acid. It is a white, shiny hexahedral crystal or a white, crystalline, slightly bitter powder. L-leucine exists naturally in organs such as the spleen and heart, and exists in various animal and plant tissues in the form of protein. It can be released after corruption and decomposition. It is one of the essential amino acids for the human body and plays an important role in maintaining normal physiological functions of the human body. Therefore, it is often used as a nutritional supplement and added to various foods, beverages and health products. It can be used to prepare amino acid infusions and comprehensive amino acid preparations for treatment or health care. |
Function |
Promote muscle growth and repair: L-leucine is an important raw material for muscle protein synthesis, which can stimulate the secretion of insulin-like growth factor (IGF-1) and promote muscle growth and repair. For fitness enthusiasts, athletes and postoperative rehabilitation patients, moderate supplementation of L-leucine can help accelerate muscle recovery and improve exercise performance. Regulate blood sugar levels: It can regulate blood sugar metabolism, promote the utilization and storage of glucose, and help maintain blood sugar stability. For diabetic patients, moderate intake of L-leucine may help improve blood sugar management. Enhance immunity: It can participate in the synthesis and functional regulation of immune cells, enhance the activity of immune cells, and improve the body's immunity. For people with weak immunity, such as the elderly and children, moderate supplementation of L-leucine can help improve physical health. Promote fat metabolism: It can stimulate the oxidative decomposition of fatty acids, promote fat metabolism, help reduce body fat accumulation, and maintain a healthy weight. Improve sleep quality: It has a sedative effect, which can help people relax their nerves and improve sleep quality. For sleep problems such as insomnia and dreaminess, moderate intake of L-leucine may help relieve related symptoms. |
