We have generalized the approach of Brodsky {\it et al.} for the intrinsiccharm quark distribution in the nucleons to the light-quark sector involvingintrinsic $\bar u, \bar d, s$ and $\bar s$ sea quarks. We compare thecalculations with the existing $\bar d - \bar u$, $s + \bar s$, and $\bar u +\bar d - s -\bar s$ data. The good agreement between the theory and the dataallows the extraction of the probabilities for the $|uudu\bar{u}>$,$|uudd\bar{d}>$, and $|uuds\bar{s}>$ five-quark Fock states in the proton. Wealso calculate the $x$-dependence of the intrinsic charm after taking intoconsideration the QCD evolution of the intrinsic quark distribution.
