Carbohydrates
Carbohydrate are
molecules that are made of only carbon, hydrogen, oxygen.
Monosaccharide's are
the simplest sugars units such as glucose. Simple sugars usually have 3-6
carbon chains. Sucrose is classed as a non reducing sugar based on its ability
to act as a reducing agent which donates electrons during a Redox reaction and
is itself oxidised.
The adehyde
functional group is the reducing agent in reducing sugars and reducing agent is
the reducing sugars have either an aldehye functional group or a ketone group
in a open chain form which can be converted into a aldehyde group.
The method to test
this is called the Benedict's test is to mix the sample with Benedict's
solution this is usually Copper (II) Sulphate. If it is a Negative result it
will turn blue. In order to test for a
non reducing sugar, you will need to first boil and dilute with HCL and then
mix with Benedict's solution and heat, a positive result will be red.
Disaccharides are two
monosaccharide's which can react to together by condensation reactions and
creates a glycosidic bond.
->Glucose + Gluclose= Maltose
->Gluclose + Fructose=Lactose
->Gluclose +
galactose=Sucrose
The polysaccharide
are long carbohydrate molecules which are formed when many monosaccharide bonds
together in condensation reactions.
