3,4-Dehydro-L-proline

Description:
3,4-Dehydro-L-proline is a non-proteinogenic amino acid characterized by its unique structure, which features a double bond between the carbon atoms at the 3rd and 4th positions of the proline ring. This modification imparts distinct properties compared to standard proline, influencing its reactivity and interactions in biochemical contexts. The compound is typically a white to off-white crystalline solid and is soluble in polar solvents such as water and alcohols. Its molecular formula reflects the presence of a pyrrolidine ring, contributing to its cyclic nature, which can affect its conformational flexibility and stability in various environments. 3,4-Dehydro-L-proline is of interest in the fields of medicinal chemistry and peptide synthesis, as it can serve as a building block for the development of bioactive compounds and may exhibit unique biological activities. Additionally, its structural characteristics make it a valuable tool for studying protein folding and stability, as well as for exploring the roles of non-standard amino acids in biological systems.
