Apiogalacturonan
Apiogalacturonans are a type of pectins known to be found in the walls of Lemna and Zostera marina. Substituted galacturonans are characterized by the presence of the saccharide appendant residue D-apiose in the case of apiogalacturonan, branching from a backbone of D-galacturonic acid residues. According to the Complex Carbohydrate Research Center, " e backbone of these polysaccharides is resistant to fragmentation by microbial EPGs." Lemnan belongs to rare apiogalacturonic pectic polysaccharides, along with zosteran from Zostera marina. The apiogalacturonan in Lemna has been researched for several nutritional and biotechnology applications in animal models. In brief, it has been shown to have gastric-protection and immune-adjuvant properties. It is also cryoprotective and this application has been patented. The apiogalacturonan from Zostera Marina currently is used in a variety of cosmetic functions. The German group Beiersdorf AG Beiersdorf AG is a German multinational comp ...

Pectin
Pectin ( grc, πηκτικός ': "congealed" and "curdled") is a heteropolysaccharide, a structural acid contained in the primary lamella, in the middle lamella, and in the cell walls of terrestrial plants. The principal, chemical component of pectin is galacturonic acid (a sugar acid derived from galactose) which was isolated and described by Henri Braconnot in 1825. Commercially produced pectin is a white-to-light-brown powder, produced from citrus fruits for use as an edible gelling agent, especially in jams and jellies, dessert fillings, medications, and sweets; and as a chemical stabiliser in fruit juices and milk drinks, and as a source of dietary fiber. Biology 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. Pectin is the principal component of the middle lamella, where it binds cells. Pectin is deposited by exocytosis into the cell wall via vesicle ...

Lemna
''Lemna'' is a genus of free-floating aquatic plants referred to by the common name "duckweed". They are morphologically divergent members of the arum family Araceae. These rapidly growing plants have found uses as a model system for studies in community ecology, basic plant biology, ecotoxicology, and production of biopharmaceuticals, and as a source of animal feeds for agriculture and aquaculture. Currently, 14 species of ''Lemna'' are recognised. Taxonomy These duckweeds were previously placed in a separate flowering plant family, the Lemnaceae, but they are now considered to be members of the Araceae. Description ''Lemna'' species grow as simple free-floating thalli on or just beneath the water surface. Most are small, not exceeding 5 mm in length, except '' Lemna trisulca'', which is elongated and has a branched structure. ''Lemna'' thalli have a single root, which distinguishes this genus from the related genera '' Wolffia'' (lacks roots), ''Spirodela'' and ''Land ...

Zostera Marina
''Zostera marina'' is a flowering vascular plant species as one of many kinds of seagrass, with this species known primarily by the English name of eelgrass with seawrack much less used, and refers to the plant after breaking loose from the submerged wetland soil, and drifting free with ocean current and waves to a coast seashore. It is a saline soft-sediment submerged plant native to marine environments on the coastlines of northern latitudes from subtropical to subpolar regions of North America and Eurasia. Distribution This species is the most wide-ranging marine flowering plant in the Northern Hemisphere. It lives in cooler ocean waters in the North Atlantic and North Pacific, and in the warmer southern parts of its range it dies off during warmer seasons. It grows in the Arctic region and endures several months of ice cover per year.Borum J., et al., (Eds.)

Beiersdorf AG
Beiersdorf AG is a German multinational company that manufactures and retails personal-care products and pressure-sensitive adhesives. Its brands include Elastoplast, Eucerin (makers of Aquaphor), Labello, La Prairie, Nivea, Tesa SE (Tesa tape) and Coppertone. Although its shares are publicly listed, Beiersdorf is controlled by Maxingvest AG (parent company of Tchibo), which directly owns 50.49% of shares. Corporate structure and business segments Beiersdorf is organized in two separate business segments: ''consumer business'' and ''Tesa''. The consumer business segment focuses on skin care, while the Tesa business, on self-adhesive products. Besides Nivea, Beiersdorf is owner of other brands like 8x4, Eucerin, Labello, La Prairie, Hansaplast and Florena. Divisional organization In 1974, the company introduced a divisional organization for cosmed, medical, pharma and Tesa. In 1989, the divisional organization was changed into skin care, adhesive products and w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
