Brief Introduction

Oxytocin Acetate is a peptide hormone


Use of  Oxytocin Acetate:

Oxytocin Acetate is a peptide hormone. Secreted by the posterior pituitary. Synthesized by the hypothalamic paraventricular nucleus and supraoptic nucleus. It consists of 9 amino acids. It is delivered to the neurohypophysis at a rate of 2 mm to 3 mm per day. The methionine residues at positions "1" and "6" form a 6-mer cyclic structure as a disulfide bond. Its physiological role: to stimulate the breast milk secretion, promote the smooth contraction of the uterus during childbirth, and promote the role of maternal love. In addition, it can reduce the level of stress hormones such as adrenal ketone in the human body to lower blood pressure.
