Mulder discovers proteins; Berzelius names them

Mulder analyzed common proteins and found they shared the same empirical formula, leading to a hypothesis about their molecular structure.

Mulder carried out elemental analysis of common proteins and found that nearly all proteins had the same empirical formula, C400H620N100O120P1S1. This observation led him to the erroneous conclusion that they might be composed of a single type of very large molecule.
