Globulins are a group of proteins found in blood plasma that play various roles in the body. They are classified into three main types: alpha, beta, and gamma globulins. These proteins are essential for functions such as transporting nutrients, hormones, and vitamins, as well as supporting the immune system. Gamma globulins, in particular, are important for immune response, as they include antibodies that help fight infections. Globulins are produced mainly in the liver and immune system, and their levels can be measured through blood tests to assess health and diagnose diseases.
