Endocrinology Series: Oxytocin, A Diverse Nanopeptide (Part 3)

Virtually all vertebrates have an Oxytocin like nonapeptide hormone that supports reproductive functions in a vasopressin-like nonapeptide hormone involved in water regulation. The two genes are always located close to each other (less than fifteen thousand DNA bases apart on the same chromosome and are transcribed in opposite directions). It is thought that two genes […]

Endocrinology Series: Oxytocin, A Diverse Nanopeptide (Part 2)

The hormone Oxytocin is used to: *Stimulate contractions of the uterus and smooth muscle tissue *Help strengthen labor *Reduce bleeding after the delivery of a baby Current evidence suggests that Oxytocin is involved in facilitating sperm transport within the male reproductive system and perhaps also in the female, due to its presence in seminal fluid.

Endocrinology Series: Oxytocin, A Diverse Nanopeptide (Part 1)

DESCRIPTION A peptide is defined as low molecular weight polymers of less than 40 amino acids joined together by amide linkages. Oxytocin, often abbreviated OXT, is included in this group and is a nonapeptide, meaning that it contains a sequence of nine peptides. The sequence is cysteine, tyrosine, isoleucine, glutamine, asparagine, cysteine, proline, leucine, and […]
