Changes in the concentration of serum proteins and their carbohydrate components during immobilization stress.

Changes in different protein fractions during immobilization stress were demonstrated. The concentration of albumins increased and that of all globulin fractions decreased, especially the concentration of alpha 2, and gamma globulins. Increased concentration of the carbohydrate components of serum proteins was also observed. Since the latter change was associated with a fall in globulin concentration, and globulins, contrary to albumins, contain carbohydrate components, it may be supposed that the proteins investigated during stress have molecules rich in carbohydrates.
