Used in biochemical research to study protein synthesis and misfolding, as it can be mistakenly incorporated into proteins in place of proline, leading to altered protein structure and function. This property makes it a valuable tool for investigating diseases related to protein misfolding, such as neurodegenerative disorders. Also studied for its potential role in plant physiology, as it is naturally produced in certain plants and may contribute to defense mechanisms against herbivores. Investigated for possible effects on cellular stress responses and aging pathways due to its impact on proteostasis.
