  We study deep inelastic scattering structure functions from hadrons using
different holographic dual models which describe the strongly coupled regime of
gauge theories in the large $N$ limit. Particularly, we consider scalar and
vector mesons obtained from holographic descriptions with fundamental degrees
of freedom, corresponding to ${\cal {N}}=2$ supersymmetric and
non-supersymmetric Yang-Mills theories. We explicitly obtain analytic
expressions for the full set of eight structure functions, i.e., $F_1$, $F_2$,
$g_1$, $g_2$, $b_1$, $b_2$, $b_3$, $b_4$, arising from the standard
decomposition of the hadronic tensor of spin-one hadrons. We obtain the
relations $2 F_1 = F_2$ and $2 b_1 = b_2$. In addition, we find $b_1 \sim {\cal
{O}}(F_1)$ as suggested by Hoodbhoy, Jaffe and Manohar for vector mesons. Also,
we find new relations among some of these structure functions.
