Peptides and Protein Drug Delivery

Peptide and Protein drug delivery system are known as Novel Drug Delivery System. Proteins and peptides are the most abundant components of biological cells. They exist functioning such as enzymes, hormones, structural element, and immunoglobulin. The twenty various naturally transpire amino acids join with each other by peptide bonds and construct polymers mentioned to peptides and proteins. Although the variance between peptides and proteins are peptide having less than 20 amino acids, having a molecular weight less than 5000, while a protein contain 50 or more amino acids and its molecular weight lies high this value. Many pharmaceutical proteins and peptides are engrossed IM, IV and Subcutaneous routes of Absorption, but the oral route is more appropriate for absorption of protein as collate to others.
