The effects of 'quark sea' in determining the flavor structure of the octet baryons have been investigated in the chiral constituent quark model ({chi}CQM). The {chi}CQM is able to qualitatively generate the requisite amount of quark sea and is also known to provide a satisfactory explanation of the proton spin and related issues in the nonperturbative regime. The Bjorken scaling variable x has been included phenomenologically in the sea quark distribution functions to understand its implications on the quark sea asymmetries like d(x)-u(x), d(x)/u(x), and Gottfried integral for the octet baryons. The results strengthen the importance of quark sea at lower values of x.
