Phe-Phe, a dipeptide composed of two phenylalanine molecules, has gained attention in various fields due to its unique properties. In materials science, it is known for its ability to self-assemble into nanostructures, making it useful in the development of biocompatible materials and drug delivery systems. Its self-assembling properties are also explored in the creation of hydrogels, which have potential applications in tissue engineering and wound healing. In biochemistry, Phe-Phe serves as a model for studying peptide interactions and aggregation, which is relevant in understanding diseases like Alzheimer's. Additionally, it is used in research to investigate enzyme kinetics and peptide-based inhibitors. Its simplicity and stability make it a valuable tool in both scientific research and practical applications.
