Hull (bran) is the outer covering of the kernel that protects it from deterioration Germ is the only living part of the corn kernel. It contains the essential genetic information, enzymes, vitamins and minerals for the kernel to grow into a corn plant. About 25% of the germ is corn oil 15 Corn is separated into its components -- starch, oil, protein and fiber -- and converted into higher value products: Corn sweeteners are the most important refined corn products.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
