Lesson 11 : Amino Acids – Classification, Properties and Peptide bonds

Peptide Bonds

1. Peptide bond formed from elimination of water from 2 amino acids resulting in CONH linkage.
2. Can have di-, tri-, oligo- and poly-peptides.
3. Proteins composed of linear polymer of amino acids.
4. Large number of proteins can exist. A small protein of 100 amino acids can have 20100 or 1.27x10130 possible unique polypeptide chains.
