The evolution of the chemical abundances at the surface of both components of Algol-type binaries is examined. First, we have examined some mixing processes which can affect element distribution in components of Algol-type stars. Second, the C abundance determinations from theoretical models are compared with values known from observational analysis. We conclude that there is no significant difference in chemical composition in components between case AB and early case B mass transfer. We have found a real difference between systems which evolve from initial mass ratios of 10/4 and 10/9.
