D-phenylalanine, also known as D-alpha-Amino-beta-phenylpropionic acid, is one of the non-proteinogenic amino acids. The biological function of D-phenylalanine remains unclear. However, it has certain anti-depressant, analgesic activities and pharmacological activity at niacin receptor II. The mechanism action of its analgesic activity seems to originate from its inhibition of enkephalin degradation by the carboxypeptidase A. Enkephalins are part of your body's natural pain relief system. When they are broken down by enkephalinase, this contributes to the sensation of pain. D-phenylalanine is specifically thought to be beneficial for reducing feelings of chronic pain. D-phenylalanine has been used with mixed results to treat chronic pain, including pain caused by rheumatoid arthritis. The primary use of D-phenylalanine as a health supplement is the relief of discomfort.
The phenylalanine system is named 2-amino-phenylpropionic acid, which is an alpha-amino acid, and the bioactive optical isomer is L-Phenylalanine (L-phenylalanine) with a specific rotation of -35.1°. Phenylalanine is one of the essential amino acids of the human body. It is white crystalline or crystalline powder solid at room temperature, sublimed under pressure, soluble in water, insoluble in methanol, ethanol, ether. Phenylalanine is widely used as a major ingredient in medicine and aspartame
It is a drug intermediate, mainly for the treatment, to prevent osteoporosis, cardiovascular, diabetes, atherosclerosis and other diseases;
It is used as a pharmaceutical intermediates or APIs for the synthesis of drugs such as nateglinide.

Phenylalanine is an amino acid. There are three forms: L-, D-, and DL- phenylalanine. L-phenylalanine is found naturally in foods such as meat and eggs.
Amino acids are the building blocks of protein. L-phenylalanine is an essential amino acid. It is the only form of phenylalanine found in proteins. D-phenylalanine is not an essential amino acid, and its role in the body is not currently understood. DL-phenylalanine is made in a lab.
People use phenylalanine for a disorder that causes white patches to develop on the skin (vitiligo). It is also used for attention-deficit hyperactivity disorder (ADHD), chronic pain, aging skin, depression, and many other purposes, but there is no good scientific evidence to support most of these uses
D-Phenylalanine is a colorless to white flake crystal or white crystalline powder, is a nutritional supplement, one of the amino acids. A nutritional supplement. Amino acids are not restricted in protein in most foods. Can be added to baked food, in addition to strengthening phenylalanine, with sugar amino - carbonyl reaction, can improve the flavor of food.
L-phenylalanine is an aromatic amino acid with physiological activity. It is one of the essential amino acids which can not be naturally synthesized by human body and animals, and it is an important component of complex amino acid infusion. Used in medicine, it is an intermediate of amino acid anticancer drugs such as phenylalanine and sarcomysin formate, and is also a raw material for the production of adrenaline, thyroxine and melanin; Studies have shown that L-phenylalanine can be used as a carrier of anticancer drugs to directly introduce drug molecules into the cancer tumor area, and its effect is 3 to 5 times that of other amino acids. This can not only inhibit the growth of cancer, but also reduce the toxic side effects of drugs.
food
Used in food, can be added to baked foods, to strengthen the nutritional effect of phenylalanine, but also with sugar amino - carboxylation reaction to improve food flavor, and supplement the human body needs functional food amino acid balance.
L-phenylalanine is the main raw material for the production of new health sweetener aspartame. Aspartame is A (1) level safety food additive identified by the World Health Organization (WHO) and the Food and Agriculture Organization (FAO) Joint Committee of experts, approved by more than 120 countries and regions, with pure sweetness and high sweetness characteristics, its sweetness is 200 times that of sucrose, and the caloric value is less than 1%. It is the ideal sweetener for people with high blood pressure, heart disease and diabetes, but it is not suitable for patients with phenylketonuria.
