The Haworth projection was named after the British chemist Sir Norman Haworth. [2] A Haworth projection has the following characteristics: [3] Carbon is the implicit type of atom. In the example on the right, the atoms numbered from 1 to 6 are all carbon atoms. Carbon 1 is known as the anomeric carbon. Hydrogen atoms on carbon are implicit. In ...
The Fischer projection is a systematic way of drawing the skeletal formula of an acyclic monosaccharide so that the handedness of each chiral carbon is well specified. Each stereoisomer of a simple open-chain monosaccharide can be identified by the positions (right or left) in the Fischer diagram of the chiral hydroxyls (the hydroxyls attached ...
In chemistry, a hexose is a monosaccharide (simple sugar) with six carbon atoms. [1] [2] The chemical formula for all hexoses is C 6 H 12 O 6, and their molecular weight is 180.156 g/mol. [3] Hexoses exist in two forms, open-chain or cyclic, that easily convert into each other in aqueous solutions. [4]
N-Acetylglucosamine molecule. N-Acetylglucosamine (GlcNAc) is an amide derivative of the monosaccharide glucose.It is a secondary amide between glucosamine and acetic acid.It is significant in several biological systems.
Haworth projection of D-psicose Allulose, also known by its systematic name D -ribo-2-hexulose as well as by the name D -psicose, is a monosaccharide and a ketohexose . [ 2 ] [ 11 ] It is a C3 epimer of fructose . [ 2 ]
Chitin is the second most abundant polysaccharide in nature (behind only cellulose); an estimated 1 billion tons of chitin are produced each year in the biosphere. [1] It is a primary component of cell walls in fungi (especially filamentous and mushroom-forming fungi), the exoskeletons of arthropods such as crustaceans and insects, the radulae ...
The chair conformation of six-membered rings have a dihedral angle of 60° between adjacent substituents thus usually making it the most stable conformer. Since there are two possible chair conformation steric and stereoelectronic effects such as the anomeric effect, 1,3-diaxial interactions, dipoles and intramolecular hydrogen bonding must be taken into consideration when looking at relative ...
