Plants Contain A Group Of Water-Soluble Carbohydrates Called Pectin In Their Cell Walls And Intercellular Tissues

Pectin 

Pectin is a structural acidic heteropolysaccharide found in terrestrial plant primary and middle lamellae and cell walls. Galacturonic acid, a sugar acid derived from galactose, is its primary constituent. Henri Braconnot isolated and described it for the first time. It is commercially produced as a white to light brown powder derived primarily from citrus fruits, and it is used in food as a gelling agent, particularly in jams and jellies. It is also used as a stabiliser in fruit juices and milk drinks, as well as a source of dietary fibre in dessert fillings, medicines, and sweets.

Pectin is a complex set of polysaccharides (see below) found in most primary cell walls and is particularly abundant in the non-woody parts of terrestrial plants. Pectin is found in primary cell walls as well as the middle lamella, where it helps to bind cells together. Exocytosis deposits pectin into the cell wall via vesicles produced in the golgi. The amount, structure, and chemical composition of pectin vary between plants, over time within a plant, and in different parts of a plant. Pectin is a polysaccharide found in the cell wall that promotes primary cell wall extension and plant growth. Pectin is broken down during fruit ripening by the enzymes pectinase and pectinesterase.

Pectin Market is a polysaccharide found in the cell wall that promotes primary cell wall extension and plant growth. Pectin is broken down during fruit ripening by the enzymes pectinase and pectinesterase, causing the fruit to soften as the middle lamellae break down and cells separate from one another. At leaf fall, a similar process of cell separation caused by pectin breakdown occurs in the abscission zone of deciduous plant petioles.
