Endosperm
Flour is made from the endosperm which makes up about 83 percent of the wheat kernel and is composed of starch and protein.

Bran
Bran is removed from the kernel and used in animal and poultry feed or combined with the endosperm to produce whole wheat flour.

Germ
The germ or embryo is the sprouting portion of the seed. It is separated from the endosperm and sold as a nutritional component for human and animal use.
