Which part of a grain kernel contains most of the starch and protein?

Explanation:
Endosperm is the energy storage part of a grain kernel, and it contains the majority of the starch granules and most of the grain’s protein. This is why refined flours, which mostly come from the endosperm, are high in starch and protein. The bran sits on the outside and is rich in fiber and minerals but has less starch and protein. The germ (the embryo) provides fats and some vitamins and minerals, not the main starch store. The hull is just the outer protective layer with little starch or protein.
