An intermediate compound formed when chlorophyllase removes the phytol chain from chlorophyll, but before complete degradation occurs.
From chlorophyll plus -ide (chemistry suffix for compounds). Emerged in early 20th-century plant biochemistry as researchers mapped chlorophyll breakdown pathways.
Chlorophyllide is a molecular ghost—it exists for mere moments during leaf senescence as an intermediate step, yet understanding it was crucial for cracking how plants recycle their nitrogen from old leaves back into new growth, saving them from nutrient waste.
