Definitions related to globulins:
  • A group of proteins that are salt-soluble and form a large fraction of BLOOD PROTEINS. There are three types of globulins, ALPHA-GLOBULINS, BETA-GLOBULINS, and GAMMA-GLOBULINS, which are distinguished from one another by their degree of electrophoretic mobility.

  • (serum globulin) A family of globular proteins found in blood that does not include albumin. These proteins are insoluble in water but solubility is increased in dilute salt solutions. Globulins are grouped into four categories (alpha 1, alpha 2, beta and gamma) based on differences in electrophoretic mobility.

  • Globulin, one of the major classifications of proteins, which may be further divided into the euglobulins and the pseudoglobulins. The former group is insoluble in water but soluble in saline solutions and may be precipitated in water that has been half-saturated with a salt such as ammonium...
