L-Phenylalanine
Description:
Product Name: L-Phenylalanine
Molecular Formula： C9H11NO2
Molecular Weight： 165.19
CAS No： 63-91-2
Phenylalanine (symbol Phe or F) is an α-amino acid. It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine. Phenylalanine is found naturally in the breast milk of mammals. It is used in the manufacture of food and drink products.
L-phenylalanine is white crystals or crystalline powder; slightly bitter taste. It dissolves readily in water and formic acid, does not solve in ethano.L phenylalanine are important food additives sweetener Aspartame (Aspartame) of the main raw material, the human body essential amino acids in one of the pharmaceutical industry is mainly used for amino acid transfusion and amino acid drugs.
L phenylalanine is human body can't synthesized a kind of essential amino acids. Food industry mainly for food sweetener aspartame synthesis raw material; Also can be used as nutritional supplement.

Function:
1) L-phenylalanine is a physiological activity of aromatic amino acids, it can't synthesis by human body and animals, it is the important ingredients of formulation of Amino acid
2) In food Industry,L – phenylalanine can be added in baked foods, improving the flavor of it, and keep our body in amino acid balance.
3) In medicine industry, L-Phenylalanine was the Pharmaceutical intermediates of Styrene-acrylic the important ingredients of adrenaline, thyroxine and melanin.
Application:
1) Nutritional supplement:
Phenylalanine is the human body essential amino acid, which is mainly used for amino acid transfusion. it have the same effect as BCAA and other amino acid, which usually can affect the body's metabolic activity, and then provide energy for the body.
2) Important food additives:
Phenylalanine is maily used as raw material of sweetener Aspartame, In most food proteins almost not limited amino acid. Can be added in baking food, in addition to strengthening phenylalanine outside, and sugar up amino - carbonyl reaction, can improve the smell of food
