Question:
Select an appropriate chemical bond among ester bond, glycosidic bond, peptide bond and hydrogen bond and write against each of the following.
a. Polysaccharide ___________________________
b. Protein ___________________________
c. Fat ___________________________
d. Water ___________________________
Solution:
a. Polysaccharides – Glycosidic bond, formed by elimination of water molecule.
b. Protein- peptide bond, it is the -CO-NH- BOND formed by elimination of water molecules.
c. Fats- ester bond, derived from an acid (organic or inorganic) in which at least one –OH (hydroxyl) group is replaced by an –O–alkyl (alkoxy) group
d. Water- H-bond, formed between the hydrogen of one water molecule and oxygen of the other water molecule.
