glucuronidation

This term is a highly specialized biochemical descriptor used almost exclusively in pharmacology, toxicology, and medicine. It describes a specific Phase II conjugation reaction in the liver, where the addition of a glucuronic acid moiety transforms lipophilic substances into hydrophilic ones, facilitating their removal via urine or bile.

Because it refers to a specific chemical process, it is treated as an uncountable noun. It is rarely used in general conversation and is typically found in peer-reviewed research papers or clinical textbooks discussing drug metabolism and clearance rates.
