Alpha-solanine is primarily known for its presence in plants of the nightshade family, such as potatoes, tomatoes, and eggplants. It serves as a natural defense mechanism against pests and pathogens, protecting the plant from herbivores and microbial infections. In the agricultural sector, understanding alpha-solanine levels is crucial for food safety, as high concentrations in potatoes, especially in green or sprouted parts, can be toxic to humans if consumed in large quantities. Researchers also study its potential pharmacological properties, including its effects on cell membranes and its possible role in cancer research due to its ability to disrupt cellular functions. However, its toxic nature limits its direct application in medicine or industry.
