(j) Carbohydrates are mostly complex molecules made up of Glucose molecules bonded
together in chains. These molecules of Glucose are of two different types: Alpha
Glucose
(-Glucose) and Beta Glucose (-Glucose).

Alpha Glucose is a ringed…

Breakage of Glycosidic Bonds
The breakage of Glycosidic Bonds between Alpha or Beta glucose Monosaccharide's in
Disaccharides and Polysaccharides is the reverse of the Condensation reaction that forms
the Glycosidic Bond. Instead of water being released…

Structure Starch is made of Amylose which is made
up of long chain Polypeptide of Alpha
Glucose molecules Glycosidically bonded
together at 1-4 linkage. Amylose is an
unbranched straight polypeptide chain that
has a coiled structure…

(n) Glycogen is used in animals as storage for excess glucose to be later hydrolysed
for Respiration. The structure of Glycogen is similar to the structure of the
polymer Amylopectin in Starch that is used for…
