25. Kohlenhydrate
- www.guidobauersachs.de
- Sie sind überwiegend Syntheseprodukte von Pflanzen, die sie als Betriebsstoffe (Zucker), als Energiespeicher (Stärke) oder als Gerüststoffe (Cellulose; Hauptbestandteil der Pflanzenzellwänden, aber auch bei Bakterien) verwenden.
- Makromolekulare Kohlenhydrate wie Stärke und Cellulose lassen sich durch Hydrolyse Unter Hydrolyse versteht man einen Vorgang, bei dem Kovalenzbindungen unter Aufnahme von Wasser gespalten werden.
- Zum Beispiel sind in der Cellulose D-Glucose-Einheiten über glykosidische Bindungen zwischen dem C-1 des einen Zuckers und dem Sauerstoffatom der C-4 OH-Gruppe des benachbarten Zuckers miteinander verknüpft.
- Die glykosidischen Bindungen in der Cellulose besitzen beta-Konfiguration. ... Die Glucose-Einheiten in der Cellulose sind also durch beta(1->4)-glykosidische Bindungen verknüpft, die man abgekürzt auch als beta1,4 oder beta-1,4 bezeichnet. ...
- Cellulose, das wichtigste Polysaccharid der Pflanzen.
- Als zweites bedeutendes Polysaccharid tritt in den Pflanzen die Cellulose auf, die mehr zur Strukturbildung als zur Ernährung dient. Tatsächlich ist die Cellulose die am häufigsten auftretende organische Verbindung in der Biosphäre. Ungefähr 1015 kg Cellulose werden jedes Jahr auf der Erde synthetisiert und abgebaut. ... Die beta-Konfiguration ermöglicht der Cellulose die Bildung sehr langer gerader Ketten. ...

- Einige Widerkäuer jedoch beherbergen in ihren Verdauungstrakten Bakterien die Cellulasen produzieren, und können daher Cellulose verdauen. ...
- Chitin ähnelt also der Cellulose, mit dem Unterschied, dass der Substituent am C-2 keine Hydroxylgruppe, sondern eine acetylierte Aminogruppe.
- Cellulose und Stärke zum Beispiel sind aus Glucoseeinheiten aufgebaut, die nahezu alle durch denselben Typ von glykosidischer Bindung verknüpft sind. ...
- Cellulose.
- Von allen organischen Stoffen auf der Erde nimmt die Cellulose der Masse nach den ersten Platz ein und bildet damit einen wichtigen und zudem laufend nachgebildeten Rohstoff. Im Vergleich zur Petro- und Kohlechemie ist aber die Verwertung der Cellulose noch wenig entwickelt.

- Cellulose Biosynthesis in Plants: from Genes to Rosettes .
- Modern techniques of gene cloning have identified the CesA genes as encoding the probable catalytic subunits of the plant CelS, the cellulose synthase enzyme complex visualized in the plasma membrane as rosettes. At least 10 CesA isoforms exist in Arabidopsis and have been shown by mutant analyses to play distinct role/s in the cellulose synthesis process. ... those undergoing either primary or secondary wall cellulose synthesis. ... Various other proteins such as the Korrigan endocellulase, sucrose synthase, cytoskeletal components, Rac13, redox proteins and a lipid transfer protein have been implicated to be involved in synthesizing cellulose but, apart from CesAs, only Korrigan has been definitively linked with cellulose synthesis. ...

- Cellulose Synthase (CesA) Genes in the Green Alga Mesotaenium caldariorum .
- Cellulose, a microfibrillar polysaccharide consisting of bundles of ß-1,4-glucan chains, is a major component of plant and most algal cell walls and is also synthesized by some prokaryotes. Seed plants and bacteria differ in the structures of their membrane terminal complexes that make cellulose and, in turn, control the dimensions of the microfibrils produced. They also differ in the domain structures of their CesA gene products (the catalytic subunit of cellulose synthase), which have been localized to terminal complexes and appear to help maintain terminal complex structure. ...

- The dominant forms of plant carbohydrate in stems, leaves, hulls, husks, cobs and the like are the structural wall polymers, cellulose and hemicellulose. ...
- Nevertheless, the majority of the world's cheap, renewable source of biomass is not found as monosaccharides but rather in the form of lignocellulose, which is primarily a mixture of cellulose, hemicellulose, and lignin. Cellulose is a homopolymer of glucose, while hemicellulose is a more complex heteropolymer comprised not only of xylose, which is its primary constituent, but also of significant amounts of arabinose, mannose, glucose and galactose. ...

- The three most common complex carbohydrates are: starch, glycogen and cellulose: .
- Cellulose is yet a third polymer of the monosaccharide glucose. Cellulose differs from starch and glycogen because the glucose-to-glucose bonds in cellulose are different and are much more difficult to break apart. Most animals (with the exception of cockroaches, cows and some other creatures) cannot digest cellulose. Since plants do not have bones to provide support for the plant, cellulose is used as a structural molecule to support leaves and other plant parts. Despite the fact that it cannot be used as an energy source in most animals, cellulose in the diet is often referred to as dietary fiber. ...
