In chemistry, a Haworth projection is a common way of writing a structural formula to represent the cyclic structure of monosaccharides with a simple three-dimensional perspective. Haworth projection approximate the shapes of the actual molecules better for furanoses —which are in reality nearly planar—than for pyranoses that exist in ...
Galactose is a monosaccharide. When combined with glucose (another monosaccharide) through a condensation reaction, the result is a disaccharide called lactose. The hydrolysis of lactose to glucose and galactose is catalyzed by the enzymes lactase and β-galactosidase.
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 ...
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.
Fischer projection of D-glyceraldehyde. Like most carbohydrates, simple aldoses have the general chemical formula C n (H 2 O) n.Because formaldehyde (n=1) and glycolaldehyde (n=2) are not generally considered to be carbohydrates, [1] the simplest possible aldose is the triose glyceraldehyde, which only contains three carbon atoms.
Haworth projection of the chitin molecule. A close-up of the wing of a leafhopper ; the wing is composed of chitin. A cicada emerges from its nymphal exoskeleton; the shed exoskeleton is mostly modified chitin ( sclerotin ) but the wings and much of the adult body are still unsclerotized chitin at this stage

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.
