These compounds are often found in nature, particularly in various fruits and plants, contributing to their aroma and flavor. These compounds have applications in the food and fragrance industries due to their pleasant scents and tastes. Additionally, gamma-lactones can be used in pharmaceuticals and chemical synthesis, making them valuable in both research and commercial products.
