What is the difference between Melatonin and Melatonin II?

Melatonin and Melatonin II are two types of peptides that are synthetic. They were developed in 1981 at Arizona University. It is related to melanin, which is a hormone that creates pigment in the skin, eyes, and hair. These peptides help change the course of skin tanning because they do not require the ultra violet rays. Another difference between them is how they are structured. Melatonin is full length and straight. Melatonin II is circular in shape and short. They are both known as being used in skin tanning, but there are other uses for the peptides. Melatonin can be used for skin disorders that make a person lighter.

Just in case you are familiar with melatonin, this is a type of synthetic peptide that has been created before at Arizona University. This was back in 1981. They are known to recreate the type of effect that is usually given by a melanocyte-stimulating hormone that will be able to produce melanin.

Melanin is needed by the body so that the pigmentation of the hair, skin, and eyes will be even. There is a difference in the structure of these two. Melatonin I will be straight and its length is full. Melatonin II, on the other hand, is known to be circular. It also has a tendency to become a bit short.
