What is the difference between oxytocin and vasopressin?
neurohypophysical hormones oxytocin and vasopressin differ in the molecular structure and function in the body of mammals. The molecular structure of each of the two hormones varies slightly with two amino acid sequences. Despite the mild molecular change between the two hormones, each has very different physiological functions. Vasopressin helps to regulate the concentrations of water and solut, while oxytocin plays a role in certain reproductive processes. The differences between oxytocin and vasopressin are also observed in mechanisms of mood and secretion.
Physiological differences between two similar hormones are caused by a slight change in the molecular structure. The amino acid sequence of vasopressin is the cyc-type-phe-gln-asn-vys-arg-gly-nh2, while oxytocin is the cyc-tyr-gln-asn-cys-for-leu-gly-nh2. One pair of amino acids that occur in oxytocin, but not vasopressin, is isoleucine (ile) and leucine (leu). Combination of phenylalanine (phe) and arginin (arg) is present in vasopressin but aboxytocin and vasopresin sent in OXytocin.
in the brain are synthesized in the brain. The different amounts of hormones are released directly into the brain. The rest of the hormones is excreted into the bloodstream by supporting proteins called neurophysin. The hormone is commonly referred to as an antidiuretic hormone for its effects on the protection of the kidneys by reducing urine production. Vasopressin secretion is regulated by osmoreceptors if factors such as thirst, blood pressure and fluid volume are simulated. Other strong stimuli of secretion of antidiuretic hormones are nausea and vomiting.
The main difference between oxytocin secretion and vasopressin is the abilities of oxytocins to relax from other tissues, including ovaries and testicles; While the only placement of vasopressin is the rear position of the rear pituitary secretion. Both sexes produce oxytocin, but women produce hormone in larger quantities than men. Oxytocin is released in large quantities during delivery and helps to facilitate breastfeeding. U birth to a childE is oxytocin excreted when the fetus simulates uterine and vagina. After release of oxytocin, the uterus contractions are improved to help the birth of the child.
oxytocin and vasopressin secretion affects moods and behavior. Women who are breastfeeding tend to have increased levels of oxytocin released in cerebrospinal fluid. Increased levels of oxytocin in women were associated with the determination of maternal behavior. Studies involving the brains of the leaks of animals infunded oxytocin show rapidly induced mothers' behavior. Instead of provoking vasopresin's behavior, it significantly affects social behavior and social links.
