Protein
Protein is a complex macromolecule consisting of Carbon, Nitrogen, Oxygen, Hydrogen, and Sulfur. It is a large biological molecules consisting one or more amino acid chains. Proteins have many different jobs including catalyzing metabolic reactions, replicating DNA, and transporting molecules from one location to another. Proteins have at least one long polypeptide which is a linear chain of amino acid residues.
Carbohydrates
Consisting of Carbon, Hydrogen, and Oxygen. Carbohydrates, are commonly referred to as sugars. They serve for the storage of energy, and also as structural components. When you hear 'carbohydrate' you often think of any food that is particularly rich in the complex carbohydrate; Starch.
Carbohydrates
Breads, Pasta, and other food rich in carbohydrates.
Pizza
Proteins
Meats and cheese are rich in protein.
Why are protein and Carbohydrates important?
The most important reason we need protein is because of our muscles. Muscle tissue is made up of two proteins, actin and myosin. They interact with each other to make muscle tissue which contract and shorten. Muscles attached to bone allow us to move. Our hearts pump blood by the action of specialized muscles. Although bone is primarily calcium, they are held together in a composite made up of protein. Foods with carbohydrates contain glucose which is a type of sugar that can be used right away for energy or stored away to be used later.
