WebHemoglobin is a good example of a protein that has a quaternary structure. Globular proteins are soluble in water and tend to be involved in metabolic functions, as opposed to fibrous proteins which tend to have a structural role. Common globular proteins include: Haemoglobin, Myoglobin, Immunoglobin Insulin Enzymes WebMyoglobin Vs Hemoglobin, The very basic difference between these terms is that myoglobin a monomeric protein that binds oxygen and supplies it to skeletal muscles, whereas hemoglobin a heterotetrameric protein found in erythrocytes. Hemoglobin transports oxygen from the atmosphere to the body.
