Protopectin is associated with which stage of fruit ripeness?

Explanation:
Protopectin is the insoluble, high‑molecular‑weight precursor of pectin found in plant cell walls. It is most abundant in fruits that are still young and firm. As the fruit ripens, enzymes break protopectin down into soluble pectins, leading to softening. So protopectin is associated with the young/unripe stage. In ripe or overripe fruits, protopectin has largely been converted or degraded, and processed fruits involve changes to pectin content from processing rather than protopectin being dominant.
