No, proteins are made up of amino acids.

Yes, at a larger scale, some proteins are monomers, made up of a single chain of amino acids, without a quaternary structure. Myoglobin is an example. About 80 % of the proteins, however, do have a quaternary structure. Haemoglobin, for example, is made up of four subunits similar to myoglobin.
