Legumin is family of globular proteins obtained from beans, peas, lentils, vetches, hemp and other leguminous seeds.[1] Garden peas are a common nutritional source for humans that contains legumin.[2]
Legumin is similar to the casein of mammalian milk and was called "vegetable casein" since it was considered analogous to the mammalian protein.[1] The primary function of the legumin protein in seeds is storage. Legumin proteins are one of the main storage proteins of angiosperms and gymnosperms.[3] Legumin is an insoluble hexameric conjugated protein with a high concentration of carbon and oxygen.
