Peptide are short chains of amino acids(the building blocks of proteins). Acting as biological “messengers,” they transmit precise instructions to cells to regulate various functions. They are found in the body, food, and many health and cosmetic products. [1, 2, 3, 4] Peptide 
Role and Uses
Peptides play specific roles depending on their structure and target: [1]
    • Skin care: Widely used in dermatology, certain peptides (such as signal peptides or carrier peptides) stimulate collagen production and promote skin repair to mitigate signs of aging. [1, 2]
    • Muscle health and metabolism:Some peptides are being studied or used in supplement form to aid in muscle mass development, recovery, and fat loss. [1, 2]
  • Medical therapy: Several peptide drugs (often prescription) are prescribed to treat osteoporosis or hormonal disorders due to their targeted action. [1]
Classification of Peptides
Peptides are classified according to the number of amino acids they contain: [1]
  • Oligopeptides: Short chains of 2 to 10 amino acids.
  • Polypeptides: Longer chains containing between 10 and 50 (or 100) amino acids.
  • Proteins: Beyond 100 amino acids, the chain takes on a complex structure and is classified as a protein. [1, 2]
