Joined by CONDENSATION reactions to for other saccharides
Made of 1 sugar molecule and are small
(CH O) - is the number of carbon atoms in the
2 n n
molecule. (have between 3 and 7 C atoms.)
Examples: glucose, galactose and fructose. ­ all have 6 C
atoms and are called HEXOSE sugars = C6H12O6.
5 C atoms are called PENTOSE sugars and 3 are called TRIOSE
sugars, the clue is in the number (a trio is a group of three, a
pentagon has 5 sides and a hexagon has 6
Carbon, hydrogen and oxygen ratio is 1:2:1
Found in fruit, nectar and milk…read more

The main sugar used in all cells for RESPIRATION.
Starch and glycogen are polymers of glucose which are
joined together in subunits
Can exist in a circular formation or in a straight line
It contains; CH2OH,
5 free Cs,
one free O,
two OHs
four free Hs
Each carbon atom has 2 Hs
and one O attached to it…read more

Formed by 2 glucose molecules in a
condensation reaction
The bond is called a GLYCOSIDIC link/bond
Called a 1,4 glycosidic bond as it forms between
