lysozyme

This term is a technical biochemical designation used primarily in medical, biological, and chemical contexts. It describes a specific protein with antimicrobial properties, and as such, it is rarely encountered in casual conversation, appearing instead in scientific literature or clinical reports.

As a chemical substance and a specific type of enzyme, it is treated as an uncountable noun when referring to the substance in general. While it can be pluralized in specific laboratory contexts to refer to different types or variants of the enzyme, it typically functions as a mass noun in general biological descriptions.
