Meaning and Definition
An enzyme that catalyzes the reversible aldol condensation reaction, splitting fructose 1,6-bisphosphate into dihydroxyacetone phosphate and glyceraldehyde 3-phosphate during glycolysis.
In biochemistry and medicine, aldolase refers to a family of lyase enzymes that facilitate the cleavage or formation of aldol (aldehyde + alcohol) bonds. Specific aldolases (A, B, C) are associated with different tissues, and elevated levels in blood serum can be a biomarker for certain muscle or liver diseases.

Mnemonic
Imagine an 'AL' chemist (ALdol) who LAZEs around (lase) because his enzyme does all the splitting work for him in glycolysis.
Conceptual Metaphor
