Biopolymer Reaction Mechanisms

Question Type 25

biopolymer condensation reactions

share in common the elimination of water in the formation of a biopolymer

biopolymer- proteins

amide linkage (N present)

reactants: carboxylic acid, amine

products: amide, water

biopolymer- sugars

ether linkage (ring shape)

reactants: two alcohols (separate rings)

products: two rings joined and water

biopolymer- triglycerides

ester linkage (no N present)

reactants: carboxylic acid and alcohol

products: ester and water

biopolymer- nylon

amide linkage (zigzag lines)

reactants: carboxylic acid and amine

products: amide and water

Polyester (PET)

Functional Groups: alcohol (-OH) and carboxylic acid (-COOH)

Linkage: ester

Polyamide

Functional Groups: amine (-NH2) and carboxylic acid (-COOH)

Linkage: amide
