是, 羟基可以连接到三键碳上. 这种构型称为烷氧基, 它通常出现在水溶性或低熔点的化合物中. 例如, the compound acetone has an alkoxy group at the position of methane (CH3-).
Its functional group is called an ester, and it typically occurs in aromatic compounds. Esters are responsible for the fragrant properties of many flowers and herbs, as well as certain types of perfume oils.
They also play an important role in the body’s chemical reactions by serving as removable terminators on macromolecules such as proteins or DNA. In addition to their useful physical properties, esters are also amphipathic molecules which means that they have both polar (嗜水的) and nonpolar (oil-loving) 地区.
