A peptide is a short chain of amino acids linked together by peptide bonds. Amino acids are the building blocks of proteins, and when they combine in a chain, they form peptides. Peptides are smaller than proteins, which are composed of longer chains of amino acids.

The structure of a peptide includes an amino terminus (N-terminus) and a carboxyl terminus (C-terminus). The bond between the carboxyl group of one amino acid and the amino group of another forms a peptide bond.

Peptides play crucial roles in various biological processes within the human body. They can act as signaling molecules, hormones, neurotransmitters, and enzymes. Additionally, some peptides have gained attention in the fields of medicine and skincare for their potential therapeutic and cosmetic applications.

For instance, certain peptides are being studied for their roles in muscle building, weight loss, and anti-aging. In the medical field, peptide-based drugs are being developed for conditions such as diabetes, cancer, and hormonal disorders. It’s important to note that while some peptides have therapeutic potential, their use should be approached with caution, and any specific applications should be discussed with healthcare professionals.
