L-Sorbitol (CAS 6706-59-8)

L-Sorbitol, a sugar alcohol derived from glucose, is a key compound in biochemical and physiological research due to its unique properties and roles in biological systems. Primarily, it functions as an osmotic agent that influences water balance within cells, making it crucial for studies related to cellular osmoregulation. In plant physiology, L-sorbitol is particularly significant, as it naturally accumulates in some fruits and plants, influencing their response to environmental stress such as drought or cold. This accumulation helps maintain cell turgor and protects cellular structures from damage caused by stress-induced dehydration. In research, L-sorbitol is used to simulate these conditions and study their effects on plant growth and survival. Additionally, this compound serves as a tool in nutritional studies, where its impact on digestion and metabolic rates can be examined due to its non-metabolizable nature in humans. This makes L-sorbitol a valuable component in the study of dietary impacts on human health, especially concerning sugar replacement and calorie reduction strategies. Furthermore, its role in the polyol pathway—a process involving the reduction of glucose to sorbitol and its subsequent conversion to fructose—makes it essential for exploring metabolic pathways in both normal and altered physiological states, enhancing our understanding of cellular metabolic processes and their implications for overall organismal health.
