Carbohydrates: Optically active poly hydroxy aldehydes
/Ketones.
Sugar: called as Saccharides. Eg:c Glucose
Saccharides
Monosaccharides → which cannot be
Classification of Saccharides hydrolysed into
smaller units
On hydrolysis,
gives two → ten
Oligosaccharides → saccharides
Oligosaccharides:
Disaccharide Sucrose hydrolysis Glucose + Fructose
Maltose hydrolysis Glucose + Glucose
Lactose hydrolysis Glucose + Galactose
Trisaccharides Raffinose hydrolysis Glucose + Fructose + Galactose
Galactose
Tetrasaccharides / Stachyose hydrolysis Glucose + Fructose + two,
preparation of Glucose:
1) By sucrose or cane Sugar [Lab method]
GHz 11 + 420 "+ Hel
dit 6641206 + 6641206
2) By starch [Commercial method]
