Overview

Phenylalanine (Phe) is one of the eight essential amino acids in the human body. It cannot be synthesized by the human body and can only be synthesized by plants and microorganisms. The amino acid is metabolized and utilized in the intestinal tract by the cells of the intestinal mucosa and may also be metabolized by the large number and complexity of microflora in the intestine.Phe is an aromatic amino acid. Most of it is oxidized by the body to tyrosine catalyzed by phenylalanine hydroxylase, with which it synthesizes important neurotransmitters and hormones, and participates in the body's glucose and fat metabolism.

There are three different types of phenylalanine: L-phenylalanine, D-phenylalanine and DL-phenylalanine. D-Phenylalanine allows for more effective pain control. L-phenylalanine helps regulate mood, appetite and mental alertness. DL-Phenylalanine can have a positive effect on pain sensitivity and mental state.

Accurate and efficient analysis and quantification of phenylalanine in plants, animals, and products is in demand in the food, pharmaceutical, nutritional, and anti-cancer fields. Creative Proteomics has an advanced HPLC-MS analytical platform to provide you with phenylalanine detection and content analysis services.
