The optical rotatory properties of 19-s γ-globulin

Abstract

• 1. The optical rotatory properties of four purified samples of human 19-S γ-globulin have been studied in detail.

• 2. The dispersion constants of the protein and the changes in the optical rotatory behaviour in polar and non-polar solvents are found to resemble those of 7-S γ-globulin.

• 3. It is suggested that the behaviour is compatible with the presence of β-form and right-handed α-helix in th molecule.
