The aldohexose that is most important in biochemistry is D-glucose, which is the main "fuel" for metabolism in many living organisms. The 2-ketohexoses psicose, fructose and tagatose occur naturally as the D-isomers, whereas sorbose occurs naturally as the L-isomer. D-Sorbose is commonly used in the commercial synthesis of ascorbic acid. [10]
l-Glucose is an organic compound with formula C 6 H 12 O 6 or O=CH[CH(OH)] 5 H, specifically one of the aldohexose monosaccharides. As the l-isomer of glucose, it is the enantiomer of the more common d-glucose. l-Glucose does not occur naturally in living organisms, but can be synthesized in the laboratory.
Cyclopropanol is an organic compound with the chemical formula C 3 H 6 O. It contains a cyclopropyl group with a hydroxyl group attached to it. The compound is highly unstable due to the three-membered ring, and is susceptible to reactions that open the ring.
The molecular formula C 3 H 6 O may refer to: . Chemistry portal; Alcohols. Allyl alcohol or 2-propen-1-ol, CH 2 =CH-CH 2 OH, CAS number 107-18-6; cyclopropanol or cyclopropyl alcohol, cyclo (-CH 2-CH 2-HOHC-), CAS number 16545-68-9
Glucose isomerase (also known as xylose isomerase) catalyzes the conversion of D-xylose and D-glucose to D-xylulose and D-fructose. Like most sugar isomerases, glucose isomerase catalyzes the interconversion of aldoses and ketoses. [24] The conversion of glucose to fructose is a key component of high-fructose corn syrup production.
For example, there are 16 distinct aldohexose stereoisomers, but the name "glucose" means a specific pair of mirror-image aldohexoses. In the Fischer projection, one of the two glucose isomers has the hydroxyl at left on C3, and at right on C4 and C5; while the other isomer has the reversed pattern.
Glucose is a sugar with the molecular formula C 6 H 12 O 6.It is overall the most abundant monosaccharide, [4] a subcategory of carbohydrates.It is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight.
Functional isomers are structural isomers which have different functional groups, resulting in significantly different chemical and physical properties. [ 11 ] An example is the pair propanal H 3 C–CH 2 –C(=O)-H and acetone H 3 C–C(=O)–CH 3 : the first has a –C(=O)H functional group, which makes it an aldehyde , whereas the second has ...
