Abstract
Moments of the quark density distribution, moments of the quark helicity di stribution, and the tensor charge are calculated in full QCD. Calculations of matrix elements of operators from the operator product expansion have be en performed on 16(3) x 32 lattices for Wilson fermions at beta = 5.6 using configurations from the SESAM collaboration and at beta = 5.5 using config urations from SCRI. One-loop perturbative renormalization corrections are i ncluded. Selected results are compared with corresponding quenched calculat ions and with calculations using cooled configurations.
