What does the suffix tase mean?

The suffix "-tase" is a common suffix used in biochemistry to indicate enzymes.

Here's how it works:

* -tase is added to the end of a word describing the substrate (the substance the enzyme acts upon) or the type of reaction the enzyme catalyzes.

Examples:

* Lactase: breaks down lactose (a sugar found in milk).

* Protease: breaks down proteins.

* Lipase: breaks down lipids (fats).

* Amylase: breaks down starches.

* DNA polymerase: adds nucleotides to a DNA strand.

Important note: While "-ase" is the most common suffix for enzymes, some enzymes have different endings. For example, "peptidase" and "kinase" are also enzyme names.
