  We investigate the propagation of a space-like flavour current in a strongly
coupled N = 2 super Yang-Mills plasma using the D3-D7 brane model at finite
temperature. The partonic contribution to the plasma structure functions is
obtained from the imaginary part of the retarded current-current commutator. At
high temperatures we find a non-vanishing result, for a high energy current,
indicating absorption of the flavour current by the quark constituents of the
plasma. At low temperatures there is no quark contribution to the plasma
structure functions.
