Question

Why are peptides important?

Answer 1

Peptides:

• They are naturally occurring short chains of amino acids (2-50 amino acids).
• Amino acids are connected via amide bonds.
• They include hormones, antibiotics, etc.
• They are formed by the transcription of genetic codes(DNA sequence).
• Also, larger proteins break down to form peptides.
• Example- milk peptides are formed by the digestion of Casein protein.
• Polypeptides fold to produce functionally active proteins.

Importance of peptides:

• Peptide hormones help in blood sugar regulation. Example- insulin, glucagon, etc.
• Examples of peptide antibiotics- colistin, actinomycin, etc.
• Some peptides are important components of proteins required by the skin.
• Example- Collagen, elastin, etc.
• Also, peptide-containing serums are used for younger-looking skin.
