Aleurone cell layer

The endosperm is surrounded by one or more layers of cells known as aleurone. In wheat, the aleurone is a single layer of thick-walled cubicle cells and constitutes 7 percent of grain weight. The cells contain about 20 percent each of protein, oil, and mineral matter. The cells are also rich in nicotinic acid. The aleurone cells also contain tiny grains of phytic acid with some protein.
