Pectic acid

Pectic acid

Pectic acid, also known as polygalacturonic acid (C18H26O19) is a water insoluble, transparent gelatinous acid existing in ripe fruit and some vegetables. It is a product of pectin degradation in plants, and is produced via the interaction between pectinase and pectin (the latter being common in the wine-making industry).
