Physical properties Description:- Monosacharides :- Monosacharides also referred to as simple sugars, are the simplest form of sugar and the most basic units of carbohydrates. Discharides :- A disaccharide also known as double sugar or bivose , is the sugar formed when two monosaccharides are joined together by glycosidic bonds. Polysacharides :- Polysaccharides are polymeric carbohydrate molecules composed of long chains of monosaccharide units bounded together by glycosidic bonds .
Classification:- Monosacharides :- Monosaccharides can be classified by the number of carbon atoms they contain for example triose (3), tetrose (4), pentose (5), hexose (6), heptose (7) and so on. Discarides :- Not further classified into different types. Polysacharides :- Homo-polysaccharides. Hetero-polysaccharide.
Solubility: - Monosacharides :- Soluble in water. Discharides :- Soluble in water. Polyscharides :- Insoluble in water.
taste Monosacharides :- Have a sweet taste. Disacharides :- Have a Sweet Taste. Polysacharides :- Do not Have a sweet taste.
Reducing Property Monosacharides :- Reducing Sugars. Disacharides :-- Reducing sugars while others are non-reducing sugars. Polysacharides :- Non reducing sugars.
No of monomers Monosacharides :- Has a single monomer. Disacharides :- Have two monomers. Polysacharides :- Is composed of a large number of monomers.
Chemical structure Monosacharies :- Have simple, linear, unbranched structures. Disacharides :- Have simple, linear, unbranched or branched structures. Polysacharides :- Have complex, branched structures.
Chemical ring structure Monosacharides :- Single ring structure . Discharides :- Two ring structure. Polysacharides :- Have many ring structures.
Molecular weight Monosacharies :- Monosaccharides have a relatively lower molecular weight when compared to disaccharides and polysaccharides. Disacharies :- Disaccharides have a relatively larger molecular weight when compared to monosaccharides. Polysacharies :- Polysaccharides have a relatively larger molecular weight when compared to disaccharides.
Size Of Particles Monosacharides :- Pass through membrane. Disacharides :- Pass through membrane. Polysacharides :- Do not pass through membrane.
