Acetylated compounds are organic molecules that have undergone a chemical modification called acetylation. This process involves adding an acetyl group, which is derived from acetic acid, to a molecule. Acetylation can change the properties of the original compound, affecting its solubility, reactivity, and biological activity. These compounds are commonly found in various fields, including pharmaceuticals and food science. For example, acetylated starch is used as a thickening agent in food products, while acetylsalicylic acid, known as aspirin, is a widely used medication for pain relief and anti-inflammatory purposes.
