POLYSACCHARIDE.
• EXPLAIN THE FORMATION OF A GLYCOSIDIC BOND BY
CONDENSATION.
• DESCRIBE THE BREAKAGE OF GLYCOSIDIC BONDS IN

PROTEINS.
, Each small organic molecule can be a unit of a large organic molecule called a macromolec
There are four classes of macromolecules (proteins, lipids, carbohydrates, and nucleic acid
Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins
made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and R
contain carbon, hydrogen, oxygen, nitrogen, and phosphorous (CHONP).
