Oxytocin

.Oxytocin acetate is an oxytocin receptor activator involved in uterine contractions and lactation. It increases Na + excretion and stimulates the muscle layer GTPase and phospholipase C. The amino acid sequence of oxytocin acetate is Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2 [disulfide bridge: 1-6].

 Function of Oxytocin

Physiological function
(1) The role of the mammary gland: The lactating mammary gland is stored in the mammary gland of the gland under the action of prolactin-producing milk. Oxytocin can contract the myoepithelial cells around the mammary gland, leading to breast milk during lactation.

(2) The role of the uterus: Oxytocin has a strong effect on promoting uterine contractions, but pregnancy is more sensitive to the uterus. Estrogen can increase the sensitivity of the uterus to oxytocin, while progesterone is the opposite.

(3) The role of shame and autism in social situations: Oxytocin can help people in social situations and be left out. However, oxytocin has no effect on people who are confident.

(4) When the mood is open or has a strong sense of belonging, the heart will secrete oxytocin and the pressure will be relieved. At the same time, the amount of oxygen in human tissue has increased dramatically.

Special effect
(1) Infant relationship
Experiments have shown that intimate attachment in infancy, the use of oxytocin, will become more caring in the mother's memory; and the relative indifference from babies and mothers to oxytocin has deepened his bad memories.

(2) Female divorce gene
The test results show that women who carry the allele of the oxytocin receptor gene variant A in the human body are generally difficult to maintain close relationship with others, and it is difficult to enter the marriage hall. Even if married, and those who do not carry genetic variation, their marriage still exists, or the probability of divorce is more than 50%. The researchers called the A allele a "divorce gene." Men with "divorce genes" have lower marital satisfaction than men.
