Biomolecules Charbohydrates –
Non- nitrogenous Hydrates of Carbon Composed of Carbon[C] Hydrogen[H]
Oxygen[O] Most Carbohydrates have H and O in ratio
2 : 1
Example : Sugar ,Starch and Cellulose
Charbohydrates
Carbohydrates
Mono Saccharides
Oligo SSaccharid
es
Poly Saccharides
Mono Saccharides
• Simplest Carbohydrates• Cannot be hydrolized into simpler
compounds
Mono Saccharides
Aldose Ketose
Contain Aldehyde Group
Contain Keto Group
Oligo Saccharides• They can be hydrolyzed into a few monosaccharide units
• Their Linkage is called Glycosidic Linkage.
Di-Saccharides
• Sucrose
Tri-Saccharides
• Ralfinose
Tetra-Saccharides
• Stchylose
Poly Saccharides:-• Hydrolyzed to many (100-1000) of mono-saccharides units
Homo Poly Saccharides• Strach, Cellulose
Hetero Poly Saccharides• Inulin
• Inulin
Reducing - Sugars
The Saccharides which reduces Fehling’s Solution nd Tollen’s reagent are reducing sugars
All mono-saccharides are reducing sugars
Non-reducing - Sugars
The Saccharides which do not reduces Fehling’s Solution nd Tollen’s reagent are reducing sugars
Di-saccharides and Poly-Saccharides are non- reducing sugars
