Melanotan 2 and Other Peptides Their Roles in Body Functions and Growth

Peptides are formed by joining amino acids and they are shorter in sequence than the larger ones that are known as proteins. Some of the most important and basic functions of the body are performed by peptides. The research laboratories in certain countries have developed various categories of peptides such as melanotan 2, which is responsible for lightening the skin tan and also used as a preventive treatment against various skin disorders that require medicines with skin lightening properties and as cure for skin cancers. Similarly, Bremelanotide is another drug, which is under clinical trial and intends to cure diseases such as sexual dysfunction and problems of erection. Although these researched compounds have proved their efficiency to a certain extent, the side-effects of these peptides are still to be dealt with by research scientists.
