Pectin is composed of complex polysaccharides that are present in the primary cell walls of a plant, and are abundant in the green parts of terrestrial plants. [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]
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.
Cell wall and middle lamella (top). The middle lamella is a layer that cements together the primary cell walls of two adjoining plant cells.It is the first formed layer to be deposited at the time of cytokinesis. [1]
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 ...
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
It is useful because pectin is the jelly-like matrix which helps cement plant cells together and in which other cell wall components, such as cellulose fibrils, are embedded. Therefore, pectinase enzymes are commonly used in processes involving the degradation of plant materials, such as speeding up the extraction of fruit juice from fruit ...
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).
