1-O-Octadecanoyl-sn-glycerol

Description:

1-O-Octadecanoyl-sn-glycerol, also known as glycerol monostearate, is a glycerol ester derived from stearic acid and glycerol. It is characterized by its long hydrophobic hydrocarbon chain, which consists of 18 carbon atoms, making it a fatty acid derivative. This compound is typically a white, waxy solid at room temperature and is soluble in organic solvents while being insoluble in water due to its hydrophobic nature. It is commonly used as an emulsifier, stabilizer, and thickening agent in food, cosmetics, and pharmaceuticals. Additionally, it exhibits surfactant properties, which allow it to reduce surface tension between different phases, facilitating the mixing of oil and water. In biological systems, 1-O-Octadecanoyl-sn-glycerol can play a role in lipid metabolism and cellular signaling. Its safety profile is generally favorable, but like all substances, it should be handled with care, and its use should comply with relevant regulations and guidelines.
