DEFINITION

Classification: 530/386

Globulins:

(under subclass 380) Proteins identified as globulins and compounds derived from these by addition to or deletion of parts of the polypeptide structure.

(1) Note. Physical Properties: Proteins which are insoluble in water at their isoelectric point are classified as globulins. The term "isoelectric point" is the pH at which a globulin will not migrate to either the cathode or anode when a direct current is passed through an aqueous suspension or dilute salt solution of the globulin.

(2) Note. Physiological properties. This group includes many enzymes and most glycoproteins. Enzymes are provided for in Class 435, Chemistry: Molecular Biology and Microbiology.

(3) Note. Examples, Euglobulins, Psendoglobulins.
