[5] Pectin is the principal component of the middle lamella, where it binds cells. Pectin is deposited by exocytosis into the cell wall via vesicles produced in the Golgi apparatus. [6]
Pectin is found naturally in many fruits, chiefly tart varieties of apples, oranges and berries like blueberries. When the fruit is heated, the pectin is activated and leached into whatever liquid ...
Modified citrus pectin (also known as depolymerized pectin, fractioned pectin, modified pectin, pH-modified pectin, low molecular weight pectin, and MCP) is a more digestible form of pectin. Modified citrus pectin is composed predominantly of D-polygalacturonates, which are more easily absorbed by the human digestive system. [2]

It is the main component of pectin, in which it exists as the polymer polygalacturonic acid. [1] In its open form, it has an aldehyde group at C1 and a carboxylic acid group at C6. Other oxidized forms of d-galactose are d-galactonic acid (carboxylic group at C1) and meso-galactaric acid (carboxylic groups at C1 and C6).
The adjective, pectinate, means supplied with a comb-like structure. This form, cognate to pecten with both derived from the Latin for comb, pectin (genitive pectinis), is reflected in numerous scientific names in forms such as pectinata, pectinatus or pectinatum, or in specific epithets such as Murex pecten.
