What Are Peptides and How Do They Affect Your Health?

The body is made up of a variety of elements from DNA that provides the cell blueprints to organs and muscles. There are a few key elements that work together to create and affect the larger cell groups that make up the various organs including the skin. Peptides along with proteins are essential to the functioning of cells.


Smaller than proteins, peptides are strings of 2 to 50 amino acids. These less defined structures typically come with multiple amino acids to create polypeptides or few amino acids to create oligopeptides. Multiple polypeptides work together to create more defined structures of proteins. These biological molecules are in each cell in the body. Compounding pharmacies like those run by Ryan Smith Lexington KY can utilize peptides to improve health and the appearance of youthful skin.


The amino acid chain determines the function of each peptide. The sequence of the amino acids also affects the peptide’s function. Moving from tissue to tissue through blood, many peptides perform the functions of hormones. Many tissues and glands produce peptide hormones. Ghrelin is a peptide that helps regulate appetite in the brain. Insulin is a common hormone that regulates blood glucose in the body. Too little insulin causes hypoglycemia whereas too much causes hyperglycemia or diabetes.


Skincare companies have begun to harness the power of peptides to slow the signs of aging and in some cases turn back time. Collagen is the most commonly sought after protein or polypeptide used in skincare. The polypeptide is essential for connective tissue and the skin by providing structural support. In essence, the polypeptide helps firm up skin reducing the appearance of fine lines and wrinkles. Other peptides used in skincare include the UV damage protecting palmitoyl tetrapeptide-7 and facial muscle-relaxing hexapeptides. Since peptides naturally occur in the body, they are generally more tolerated than Vitamin C and retinoids in skincare products.
