Vacuum QCD and new information on nucleon structure functions

It is shown, that specific chirality and flavor properties of the instanton-induced interaction allow us to explain the observed violation Ellis-Jaffe and Gottfried sum rules. A large value of these violations originates from the anomalous growth of the instanton-induced interaction between quarks at high energy. The new sum rule which connect the values of violations of Ellis-Jaffe and Gottfried sum rules have been obtained.
