Studies related to thermodynamic quantities of nucleons present interesting and topical questions. In this work, for the first time we apply Page\u2019s theory of the studies of black holes to investigate the entropy of a proton system. Inspired by the quantum entanglement entropy in black hole information theories, we establish the proton entanglement with the similar way. Based our calculations, the proton entanglement entropy has the approximate form <math><mi>S</mi><mo>=</mo><mi>ln</mi><mi>m</mi><mo>\u2212</mo><mn>1</mn><mo>/</mo><mn>2</mn></math>, where <math><mi>m</mi></math> represents the partons density of proton (mainly gluon and sea quark contributions) at small Bjorken <math><mi>x</mi></math>. Our calculations using Page\u2019s theory are well in agreement with the recent deep inelastic scattering measurements from the H1 Collaboration."
