In this paper we study relations between different (q, h)-Weyl algebras. We also show an embedding of the q-deformed universal enveloping algebra U-q = U-q(sl(2)) into a tensor product of two (q, h)-Weyl algebras when q not equal 1. This allows us to study the limiting case q -> 1 in the so-called structure ladder of U-q.
