  The chiral partner structure of heavy baryons is studied using the bound
state approach by binding the heavy-light mesons to nucleon as soliton in an
effective Lagrangian for the pseudoscalar and vector mesons based on the hidden
local symmetry. In the heavy-light meson sector, we regard the $H$-doublet and
$G$-doublet as chiral partners and couple them to light meson with minimal
derivative. We find that the chiral partner of $\Lambda_c(1/2^+,2286)$ is the
$\Lambda_c(1/2^-,3/2^-)$ heavy quark doublet with the mass of about 3.1\,GeV
but not ($\Lambda_c(1/2^-,2595)$, $\Lambda_c(3/2^-,2625)$) which might be
interpreted as an orbital excitation of the $\Lambda_c(1/2^+,2286)$. The same
model is applied to the bottom sector, and the chiral partner of
$\Lambda_b(1/2^+,5625)$ is shown to have the mass of about 6.5\,GeV. The chiral
partner structures for the isospin vector heavy baryons are also discussed. For
the pentaquark states, we find that the masses of the pentaquark state made of
ground state heavy-light meson and its chiral partner are similar, and both of
them are below the $Dp$ threshold, which therefore cannot be ruled out by the
present data.
