This research investigates Trehalose as a naturally occurring disaccharide that plays a crucial role in cellular protection by stabilizing proteins and membranes, scavenging free radicals, and acting as an osmoprotectant under various stress conditions. Its therapeutic potential has been explored in the treatment of neurodegenerative diseases, diabetes, and cardiovascular disorders, primarily due to its ability to induce autophagy, reduce oxidative stress, and inhibit protein aggregation.
