These protein types serve as essential components to your body's construction. Keratin and collagen are the most common structural proteins. These are strong, fibrous proteins. Keratin forms the structure of your skin, nails, hair and teeth. While, collagen serves as a connective structure for your tendons, bones, muscles, cartilage and skin in particular.
The four structure types are primary, secondary, tertiary, and quaternary structure. A protein's structure determines its function. For instance, structural proteins such as collagen and keratin are fibrous and stringy.Globular proteins like hemoglobin, on the other hand, are folded and compact. Hemoglobin, found in red blood cells, is an iron containing protein that binds oxygen molecules.hen a number of amino acids are linked together by peptide bonds, a polypeptide chain is formed. One or more polypeptide chains twisted into a 3-D shape forms a protein.
