What are peptides composed of?

Peptides are indeed composed of short chains of amino acids linked together by peptide bonds. This specific structure is fundamental to their function in biological processes. Amino acids are the building blocks of proteins, and when they are connected by peptide bonds, they form a peptide, which can vary in length. These peptides can serve numerous roles in the body, including acting as hormones, neurotransmitters, and signaling molecules that regulate various physiological functions.

Understanding peptides as chains of amino acids helps clarify their significance in skincare and beauty therapy, particularly because many cosmetic products leverage peptides for their ability to promote collagen production, improve skin texture, and provide anti-aging benefits. This knowledge is crucial for estheticians and beauty therapists in selecting effective ingredients for treatments and products.
