[ad_1] noun Biochemistry.
- any of a group of proteins, as myosin, occurring in plant and animal tissue, insoluble in pure water but soluble in dilute salt solutions and coagulable by heat.
- any of several groups of blood plasma proteins, divided into fractions, as alpha, beta, or , depending on electrophoretic mobility.
- any of a group of simple proteins, including gamma globulin, that are generally insoluble in water but soluble in salt solutions and coagulated by heat
- Any of a family of proteins that are precipitated from plasma by ammonium sulfate and may be further fractionated into many subgroups that differ with respect to associated lipids or carbohydrates.
- A major class of proteins found in the seeds of plants and in various tissues and substances of vertebrate and invertebrate animals, including blood, muscle, and milk. The globulins in blood comprise all the plasma proteins besides albumin. Two kinds, alpha and beta globulin, are primarily transport proteins or serve as substrates for forming other substances, and include lipoproteins and enzymes. A third kind, the gamma globulins, consists almost entirely of the immunoglobulins. Most globulins are insoluble in water but soluble in saline solution.
