A scientist who studies the chemical processes related to the immune system.
The immunochemist conducted experiments to understand how antibodies work.
Immunochemist → It is formed from "immunis" (from Latin, meaning exempt or free from) and "chemist" (from Greek "khēmia", meaning the art of transmuting metals). The word refers to a scientist who studies the chemistry of the immune system, focusing on how substances interact with immune responses.
Think of someone who is 'exempt' ('immunis') from diseases and studies the 'chemistry' ('khēmia') of the immune system — that's what an immunochemist does.
