However, Gerardus Johannes Mulder is known for his important research on proteins in the 1830s and 1840s. Specifically:
* He coined the term "protein" in 1838. He did this after identifying the fundamental chemical composition of proteins as containing carbon, hydrogen, oxygen, and nitrogen. This was a major contribution to our understanding of the building blocks of life.
* He studied the chemical composition of various substances like casein, albumin, fibrin, and gelatin. He observed that these substances were similar in their composition, leading to his identification of "protein" as a fundamental class of molecules.
Therefore, while he did not make a specific discovery in 1838, his work with proteins began around this time and led to his important discovery of the term "protein" itself.
