Aleuron
Definition
A reserve protein substance, with an amorphous or crystalloid granular structure, deposited in the cells of the outermost layer of the endosperm in plant seeds (particularly in grasses). It represents a biochemical complex rich in amino acids, phosphates, and enzymes, playing a vital structural role in nourishing and metabolically supporting the embryo during the early stages of germination.
