Peptides are naturally occurring molecules that are smaller than proteins and which consist of two or more amino acids. They are considered to be short chains of amino acid monomers which are linked by peptide bonds. They are considered to be building blocks of proteins. There are several classes of peptides which depend on how they are produced. They are peptones, ribosomal peptides, non ribosomal peptides, milk peptides and peptide fragments. They can be referred by different names such as polypeptides, dipeptides and so on depending on the amount of amino acids contained in them.

Proteins are broken down into peptides through enzymatic action so as to make them work effectively in the body. They are easily used in the body since they do not need to be broken down due to their smaller size. They are considered to be more useful to the body due to their stable nature unlike amino acids which are considered to be very unstable. Peptides have different functions in the body such as regulating the various functions by directly interacting with respective cells. Some of them have immune activity while some are known to have hormone activity.

Some peptides act as cell communicating ingredients that control how cells react to diet and physical exercise. They are very important in wound healing and controlling the pathology of skin conditions such as eczema and dermatitis. When the skin’s collagen breaks down, specific peptides are formed which send signals to your skin to form new collagen to replace the damaged one. Peptides can also be applied topically to trigger the skin into forming new collagen even when it has not been broken down.

They are very common in the fitness world especially among athletes. They are also known to burn fat, build muscle and improve athletic performance. It achieves this by enabling the body to absorb more amino acids and make them easily available for the cells immediately after workout. It also helps to recover very quickly especially after an injury by encouraging of more muscle formation at a rapid rate and less fat formation during that process.

They have become the most common way of increasing muscle mass since they have an anabolic effect on the muscle mass of an athlete. They are also known not to have any side effects unlike steroids. Peptides are not easily detected in blood and urine samples unless a comprehensive test is carried out to detect it.
