What is globular protein?

Globulin, also known as globulin, is a protein formed by the compaction of amino acid chains, and folded to form a complex shape similar to a sphere This protein is one of the three major protein groups The other two groups are fibrin and membrane protein, which are usually found at the junction of cell membrane and organelle The main difference between globular protein and fibrin is that the former is soluble in water and therefore visible in plasma, while the latter is not Globulins can play many roles They can be enzymes, biological messengers and transport mechanisms, and can play the role of structural proteins in animal cells Almost all enzymes are globular proteins with different shapes, sizes and complexities The role of enzyme in biochemistry is catalyst, which is used to speed up or slow down chemical reaction rate Some common examples of globular proteins are amylase and lactose lyase Amylase can be found in human saliva and helps break down starch into simple sugars during digestion Lactose decomposing enzyme is an enzyme that can make the human body digest lactose People who lack this enzyme are often lactose intolerant Globular proteins also act as biological messengers in the form of polypeptide hormones Peptide hormones are important in metabolism, growth and development Prolactin and insulin are some of these polypeptide hormones Prolactin is a hormone secreted by the pituitary gland, which can induce lactating mothers to secrete milk Insulin, a hormone secreted by the pancreas, helps the body regulate energy and metabolize sugar Another important function of globulin is the biological transport mechanism, usually in the form of globulin and serum albumin Globulin and serum albumin are serum proteins, also known as blood proteins, which can be found in the active plasma Another familiar form of globulin is heme, a globular protein synthesized in blood cells and responsible for the transfer of oxygen to the whole body Serum albumin is produced in the liver and transports fatty acids and haemagglutinins, an iron rich compound that provides color to red blood cells Although globular proteins play a major role in messenger or transport proteins, they also play a structural role in animal cells Globular proteins called microtubules are responsible for the production of microtubules in cells Microtubule is an important part of cytoskeleton and a scaffold to keep cells in shape and structure Globular proteins called structural patterns can also be found in the cell membrane, where they provide the cell structure again.
