methionine
This term is a technical chemical designation used primarily in biochemistry and molecular biology. It carries a neutral, scientific register and is almost exclusively found in academic papers, medical textbooks, or laboratory reports.
As a specific chemical compound, it is treated as an uncountable mass noun. It refers to the substance itself rather than individual molecules, meaning it does not typically take a plural form in standard scientific discourse.
