PhospholipaseD, cabbage is an enzyme from the phospholipase superfamily, prevalent across bacteria, yeast, plants, animals, and viruses, and is frequently utilized in biochemical research. It catalyzes the hydrolysis of the phosphodiester bond in glycerophospholipids, resulting in phosphatidic acid and soluble choline. This enzyme is involved in various disease-related processes, such as diabetes, atherosclerosis, obesity, tumor development, immune responses, and neuroendocrine functions.
