More Basic view


Ala-Phe-OH is a dipeptide compound that functions as a substrate in enzymatic reactions. It plays a role in peptide synthesis and serves as a building block for the formation of larger peptide chains. Ala-Phe-OH′s mechanism of action involves its ability to undergo specific chemical reactions with other compounds, leading to the formation of peptide linkages. This dipeptide compound facilitates the study of enzymatic processes and the synthesis of peptides in experimental applications. Its molecular structure allows for precise interactions with enzymes, enabling the investigation of peptide bond formation and enzymatic catalysis.


 Possibly Effective for

    A skin disorder that causes white patches to develop on the skin (vitiligo). Taking L-phenylalanine by mouth, or applying it to the skin, both in combination with UVA light, seems to improve symptoms of vitiligo.

Possibly Ineffective for

    Attention deficit-hyperactivity disorder (ADHD). Taking phenylalanine by mouth doesn't seem to help ADHD.
    Chronic pain. Taking D-phenylalanine by mouth does not seem to reduce pain.

There is interest in using phenylalanine for a number of other purposes, but there isn't enough reliable information to say whether it might be helpful.
