For a finite-dimensional Lie
algebra L over a field of characteristic 0, the structure of the Hopf algebra of
representative functions of L, ℋ(L), is known in some detail from Hochschild, Illinois
J. Math., 1959 and 1960. Depending on these results, we demonstrate sufficient
conditions for a Hopf algebra over an algebraically closed field of characteristic 0 to
be isomorphic to ℋ(L) for some Lie algebra L.
