Protein

4. contain two major forms of protein: whey and casein.
5. is a good source of certain nutrients, especially vitamin B-12 and iron.
6. acts on fats and performs hydrolysis of fats (not of carbohydrates, fats and proteins).
8. is the protein that makes blood red. It is composed of four protein chains, two alpha chains and two beta chains, each with a ring-like heme group containing an iron atom.
10. is the principal enzyme involved in protein digestion
11. can delay proteolytic degradation of protein partners (e.g., histatin 1) when complexed and has the function in carbohydrate breakdown.
13. are accumulated in legume seeds during development inside protein bodies (storage vacuoles) and provide ammonia, carbon, and amino acids during seed development.
14. are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein.

1. is an enzyme (a protein that causes a chemical reaction to occur) normally produced in your small intestine that's used to digest lactose.
2. forms filaments that provide cells with mechanical support and driving forces for movement.
3. is protein molecules made up of amino acids
7. is an enzyme that catalyzes proteolysis, breaking down proteins into smaller polypeptides or single amino acids, and spurring the formation of new protein products.
9. are a staple source of calories, carbohydrates, B-vitamins, and protein
12. is the prototype of a molecular motor—a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement.
