prothrombin
This term is a specialized biochemical designation used primarily in medical, hematological, and biological contexts. It describes a zymogen, meaning it is a protein that remains dormant until a specific chemical trigger activates it into thrombin to facilitate coagulation.
As a technical term for a specific protein, it is treated as an uncountable mass noun. It refers to the substance itself rather than individual molecules, and therefore does not typically appear in plural form in scientific literature.

I need to remember that prothrombin is a zymogen, meaning it is an inactive precursor.
