Common_NamePectic acid
DescriptionPectic acid is a water insoluble, transparent gelatinous acid existing in ripe fruit and some vegetables. Pectic acid exists in the cell walls of plant tissues, and these substances are ingested from vegetables, fruits, etc. Pectic substances are dealt with as dietary fibers, but other physiological functions are not clear. Pectic acid is degraded in the digestive tract of man and it is considered that digestion is by the action of intestinal bacteria. Pectic acid is mainly degraded to 4,5-unsaturated digalacturonic acid and perhaps to 4,5-unsaturated trigalacturonic acid, by the action of the enzymes from bacteria such as Bacteroides sp. and Clostridium sp. in the human digestive tract. Then, they are used as carbon sources by these pectic-acid-using bacteria. (PMID: 12111144)
