The word "Cellobiose" is spelled with two "l's" and two "o's," as it is derived from the combination of two words, "cellulose" and "obiose." The IPA phonetic transcription for this word is "/ˌsɛləʊˈbaɪəʊs/." The first syllable is pronounced with a short "e" sound, while the second syllable has a long "o" sound. The final syllable has a diphthong with the "i" and "o" sounds. Cellobiose is a disaccharide made up of two glucose molecules, commonly found in plant cell walls.
Cellobiose is a noun that refers to a disaccharide composed of two glucose molecules linked together by a β-1,4 glycosidic bond. It is a crystalline, white or colorless solid that is commonly found in various plant materials such as cellulose, the main component of the cell walls of plants. Cellobiose can also be produced by the partial hydrolysis of cellulose.
The molecular formula of cellobiose is C12H22O11, and it has a molecular weight of approximately 342.3 grams per mole. It is classified as a reducing sugar due to its ability to undergo oxidation reactions.
Cellobiose serves as an important source of energy for certain microorganisms, as they possess specific enzymes called cellobiases that can break down cellobiose into its constituent glucose molecules. These glucose molecules can then be used as a fuel source for the cell's metabolic processes.
Additionally, cellobiose is of interest in industries such as food and pharmaceuticals. It has potential applications as a low-calorie sweetener and a prebiotic, which can promote the growth of beneficial bacteria in the gut. Furthermore, cellobiose can be enzymatically converted into cellotriose, cellotetraose, and other oligosaccharides with various industrial uses, including the production of biofuels.
Overall, cellobiose is a crucial disaccharide that plays a significant role in the biochemistry of plants, microorganisms, and potential applications in several industries.
The word "cellobiose" is derived from two components: "cello-" and "-biose".
"Cello-" is derived from "cellulose", which is a complex carbohydrate found in the cell walls of plants. Cellulose consists of a chain of glucose units, which are bonded together through beta-1,4-glycosidic linkages.
"-Biose" is derived from the Greek word "bios", meaning "life". In chemistry, "biose" refers to a sugar (carbohydrate) molecule consisting of two monosaccharide units bonded together.
Therefore, "cellobiose" refers to a disaccharide consisting of two glucose units linked together through a beta-1,4-glycosidic bond. It is an important component in the structure of cellulose.
