4-sulfo-L-phenylalanine

Description:
4-Sulfo-L-phenylalanine, also known as sulfonated phenylalanine, is an amino acid derivative characterized by the presence of a sulfonic acid group (-SO3H) attached to the para position of the phenyl ring of phenylalanine. This modification enhances its solubility in water and alters its interaction with biological systems, making it useful in various biochemical applications. The compound retains the basic structure of phenylalanine, which includes an amino group (-NH2), a carboxylic acid group (-COOH), and a side chain that contains a phenyl group. The sulfonation introduces additional polar characteristics, which can influence its behavior in protein folding, enzyme activity, and receptor binding. Due to its unique properties, 4-sulfo-L-phenylalanine is often utilized in research related to protein chemistry, drug design, and as a potential therapeutic agent. Its CAS number, 34023-49-9, is a unique identifier that facilitates the cataloging and identification of this specific chemical substance in scientific literature and databases.
