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.
A single protein molecule may contain one or more of the protein structure types. 1  Primary Structure - describes the unique order in which amino acids are linked together to form a protein. 2  Secondary Structure - refers to the coiling or folding of a polypeptide chain that gives the protein its 3-D shape. There are two types of secondary structures observed in proteins. One type is the alpha (Î±) helix structure. This structure resembles a coiled spring and is secured by hydrogen bonding in the polypeptide chain.
