What is the difference between alpha glucose and beta glucose?
In alpha glucose, at Carbon 1 H is above the plane and OH is below the plane.
In beta glucose, at Carbon 1 OH is above the plane and H is below the plane.
What is the definition of isomer?
Isomers are molecules with the same molecular structure but with a different arrangement of atoms in space.
What is another name for glucose?
Hexose Monosaccharide
What is another name for ribose?
Pentose monosaccharide
What is a condensation reaction?
A condensation reaction is a reaction that occurs when 2 monosaccharides join together to form a disaccharide and water.
What is a glycosidic bond?
A glycosidic bond forms between 2 monosaccharides that join together to form a disaccharide.
What is a 1,4-glycosidic bond?
A 1,4-glycosidic bond forms between the carbon 1 of one glucose molecule and the carbon 4 of another glucose molecule.
