Legumin

Legumin is family of globular proteins obtained from beans, peas, lentils, vetches, hemp and other leguminous seeds. Garden peas are a common nutritional source for humans that contains legumin.

Legumin is similar to the casein of mammalian milk and was called "vegetable casein" since it was considered analogous to the mammalian protein. The primary function of the legumin protein in seeds is storage. Legumin proteins are one of the main storage proteins of angiosperms and gymnosperms. Legumin is an insoluble hexameric conjugated protein with a high concentration of carbon and oxygen.
