WebbProteins are composed of amino acid chains, and structure levels are up to four. Certain specific protein examples include collagen, insulin, and anticorps. What characterizes a protein? Proteins are macromolecular polypeptides, that is, very large molecules (macromolecules) made up of several amino acids bound to the peptides. WebbProteins have different shapes and molecular weights. Some proteins are globular in shape; whereas, others are fibrous in nature. For example, hemoglobin is a globular protein, but collagen, located in our skin, is a fibrous protein. Protein shape is critical to its function, and many different types of chemical bonds maintain this shape.
