BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Pectin is a major component of the primary cell walls of dicotyledonous plants and is also present in smaller amounts in the secondary walls of dicots and both types of cell walls in monocots (Vogel, 2008).

Detailed explanation-2: -The pectin polymer homogalacturonan (HG) is a major component of land plant cell walls and is especially abundant in the middle lamella.

Detailed explanation-3: -It exists primarily in plant cell walls and helps bind cells together. Some fruits and vegetables are more pectin-rich than others. For example, apples, carrots, oranges, grapefruits, and lemons contain more pectin than cherries, grapes, and other small berries with citrus fruits containing the most pectin.

Detailed explanation-4: -Pectin is a major component of primary cell walls of all land plants and encompasses a range of galacturonic acid-rich polysaccharides. Three major pectic polysaccharides (homogalacturonan, rhamnogalacturonan-I and rhamnogalacturonan-II) are thought to occur in all primary cell walls.

Detailed explanation-5: -Complete answer: Structurally, pectin is an acidic hetero-polysaccharide, it is found in the lamella and cell walls of terrestrial plants.
