We give a construction of the whole quantum group associated to a symmetrizable Kac-Moody Lie algebra as a quantum quasi-symmetric algebra, a particular case of multi-brace cotensor Hopf algebras, in the spirit of the quantum shuffle construction of the “plus part”. All highest weight irreducible representations are constructed using this machinery. It also provides a systematic way to construct simple modules over the quantum double of a quantum group.
