πŸ”† Peptides, Proteins & Hormones β€” Understanding the Difference

πŸ“ Why in News?
🟒 Bengaluru’s first β€œPeptide Party” was cancelled after 200+ registrations for around 50 places, highlighting the growing interest in peptides and their potential health applications.

πŸ“ Amino Acids β€” Building Blocks
🟒 Amino acids are the basic building blocks of peptides and proteins.
🟒 Humans use 20 different amino acids, which combine in different sequences to form proteins.

πŸ“ Peptides vs Proteins
🟒 Peptides: Relatively short chains of amino acids, generally 2–50 amino acids.
🟒 Proteins: Larger chains, generally 50+ amino acids, with more complex folded structures.
🟒 Both occur naturally in the body and can also be synthesised.

πŸ“ Key Functions
🟒 Peptides: Often act as signalling molecules and regulate biological functions; some can reduce inflammation and support muscle-building processes.
🟒 Proteins: Help build tissues, transport molecules and support immune responses.
🟒 Hormones: Act as chemical messengers, carrying signals between cells and organs.

πŸ“ Important Point
🟒 A hormone is defined by its function, not its molecular structure.
🟒 Hormones can be proteins, steroids or amino-acid derivatives.
🟒 Some peptides and proteins can therefore function as hormones.

πŸ“ Therapeutic Applications
🟒 Peptides: Insulin and semaglutide are established peptide medicines.
🟒 Proteins: Used in enzyme-replacement therapies and monoclonal antibody treatments.
🟒 Hormone therapy: May use synthetic or bioidentical hormones.

πŸ“Œ Prelims Quick Revision:
🟒 Amino acids β†’ building blocks
🟒 Peptides β†’ shorter amino-acid chains
🟒 Proteins β†’ larger, complex structures
🟒 Hormones β†’ chemical messengers; may be peptides, proteins, steroids or derivatives
