What are peptides?

Peptides are short chains of amino acids that are linked together by peptide bonds. They are fundamental components of proteins and play various roles in biological functions. Peptides can act as signaling molecules, hormones, and can have important roles in skin care and rejuvenation, as they can help stimulate collagen production and improve skin elasticity. This is why in the context of esthetics and skin care, an understanding of peptides is crucial for both the development of effective treatments and the formulation of cosmetic products.

Long chains of fatty acids are known as lipids or fats, which do not fit the definition of peptides. Similarly, complex carbohydrates refer to long-chain sugars and starches that are not related to the structure of peptides. Vitamins and minerals are micronutrients necessary for various bodily functions but are not composed of amino acids. This highlights the specificity and significance of peptides within the larger context of biological and cosmetic applications.
