What is the pyranose and furanose formula for aldohexose?
pyranose is a collective noun of carbohydrates that have a six membered ring system which is 5 carbons and one oxygen. example: glucose Furanose is a collective noun of carbohydrates that have a five membered ring system which is 4 carbons and one oxygen. example: fructose
What kind of sugar is used in RNA?
These are ribose sugars. In DNA, there are deoxyribose sugars. In ribose sugar (pyranose or furanose), we can see H and OH bond to the second carbon other than two carbon bonds.
What is the chemical formula for allose?
C6h12o6
What is meant by alpha and beta carbohydrates?
The term Alpha and Beta carbohydrates refer to the configuration of the hydroxyl group on the anomeric carbon, or the number 1 carbon on aldoses, or the number 2 carbon in ketoses. If you are drawing the pyranose or furanose structures of these compounds, alpha refers to the hydroxyl group pointing down and beta refers to the hydroxyl being up.
How many members are there in a pyranose ring?
six
Explain the differences and similarities of pyranose and furanose ring?
1.when the cyclic sturcture of glucose(hexose) is six-membered ring resembling the pyran ring, thus they are called pyranosewhile when hexoses are found in five-membered ring resembling furan ring, thus they are called furanose2.in aldohexose:The interaction between c=o and the secondary OH is found at c5 if it was pyranosethe interaction between c=o and the secondary OH is found at c4 if it was furanosein ketohexose:the interaction between c=o and the secondary OH is found at c6 if it was pyranosethe interaction between c=o and the secondary OH is found at c5 if it was furanose
Draw the haworth projection of the furanose forms of D-arabinose?
hallo
How many disaccharides are theoretically possible starting from D- glucose in the pyranose form?
19
What is an anomeric carbon?
In cyclic form of monosaccharide two forms are possible depending upon the position of -OH group,if it is present below the plane it is known as alpha position and if it is above the plane ,it is known as beta position. The two diastereomers are called anomers.the hemiacetal or hemiketal carbon is called as anomeric carbon.for examplein glucose, C-1 carbon is known as anomeric carbon.
What can the structure of glucose be classified as A. L-monosaccharide B. Ketose C. Disaccharide D. D-monosaccharide E. Furanose?
PENIS
What do a glucose molecule and a fructose molecule have in common?
They both have the same molecular formula, C6H12O6, although their atoms are arranged differently. They are both simple sugars and can be metabolised for energy. They are both water soluble and taste sweet.
What is the molecule H2C6H6O6?
There is not one, but several answers to this question.A molecule with the formula C6H12O6 is called a hexosebecause it is a simple sugar (monosaccharide) that contains six carbon atoms.We most often refer to C6H12O6 as glucose. However, there are many isomers of glucose: an isomer is simply a different arrangement of atoms. The following sugars all have the molecular formula C6H12O6, but the carbon, hydrogen, and oxygen atoms in each sugar are arranged differently:- Allose- Fructose- Galactose- Glucose- Gulose- Idose- Mannose- Psicose- Pyranose- Sorbose- Tagatose- TaloseThere are other hexose sugars, most of which are not naturally-occurring but rather synthesized.
