Monosaccharides
Disaccharides
Polysaccharides
2 types of carbohydrates that are referred to as sweet and simple sugars

The type of carbohydrate that glucose is is a ‘…’
Monosaccharide
Monosaccharides and disaccharides always end in ‘…’
Ose
E.g glucose, maltose, fructose, sucrose …

Arrangement of atoms
Isomers are…with the same chemical formula but different arrangements of atoms
Molecules
Isomers are molecules with the same chemical formula but different…
Arrangement of atoms
Isomers are molecules with the same…but different arrangement of atoms
Chemical formula
Alpha glucose and beta glucose are … of each other meaning that they have the same chemical formula but a different arrangement of atoms
Isomers
The 2 different structures of glucose molecules are a…. glucose and b… glucose
Alpha
Beta
ABBA stands for…and means
Alpha above
Beta below
(In terms of where OH is when drawing right hand side of glucose molecule)
When you draw glucose molecules for the alpha glucose molecule on the right hand side the OH is below, for the beta glucose molecule on the right hand side the OH is above
2 alpha glucose molecules join together to form …
Maltose (which is a disaccharide)
Maltose is a ….(type of carbohydrate)
Dissacharide
2…glucose molecules join together (condensation reaction) to form maltose which is a disaccharide
Alpha
Disaccharides are formed by the condensation of 2…
Monosaccharides
(They can be the same or different depending on which disaccharide is being formed)
Disaccharides (e.g maltose) are formed by the….of 2 monosaccharides
Condensation
Disaccharides (e.g maltose) are formed by the condensation of…monosaccharides
2
(The monosaccharides can either be 2 of the same type e.g 2 alpha glucose molecules or 2 different e.g glucose and fructose, depending on which disaccharide is being formed)
A condensation reaction between 2 monosaccharides forms a…bond
Glycosidic
Type of carbohydrate that is referred to as complex carbohydrate
Polysaccharides
Proper term for complex carbohydrates
Polysaccharides
Proper term for sweet and simple sugars (there are 2 types)
