The Human Growth Hormone and Its Effects on Our Bodies as We Age

In this paper, I will explain what the human growth hormone is; its effects on our bodies as we age. Also, show the benefits received by following a prescribed treatment plant from a qualified physician. The results are amazing, as you will see; this has prompted more research into the benefits of hormone replacement therapy as we age. What is Human growth hormone:HGH is a compound protein molecule of 191 amino acids linked in a specific sequence. It is secreted in pulses by the pituitary gland. These pulses differ between 10 and 30 per day and can be strengthened by exercise. For years, doctors have prescribed HGH therapy for children who needed a growth enhancement. HGH is essential for tissue repair, healing, muscle growth, bone strength, brain function, physical and mental health, energy, and metabolism. The genes forhuman growth hormone are limited to a small area in the region of chromosome17 and are closely related to human chorionic somatomammotropin (hCS), also known as placental(lactogen) genes. GH, human chorionic somatomammotropin (hCS), and prolactin (PRL) make up, a group of homologous hormones with growth-promoting and lactogenic activity.

Human Growth Hormone Breakdown:

Amino acids are biochemical building blocks. They form small chemical chains calledpolypeptides or peptides, which in turn develop structures called proteins with a molecular weight of about 22,000. The structure includes four helices essential for functional interaction with the GH receptor. GH is structurally and actually evolutionarily homologousBowerman 2prolactin and chorionic somatomammotropin. In spite of marked structural similarities among growth hormone from different species only human and primate, growth hormone is active in humans. GH is secreted into the blood by the somatotrope cells in the anterior pituitary, which produce growth hormone. The anterior pituitary produces and secretes several peptide hormones that regulate many physiological processes including stress, growth, and reproduction.Somatropin:Somatropin is the synthetic form of human growth hormone. Each manufacturer of somatropin assigns its own brand name, such as Saizen, Genotropin, Humatrope, Nutropin and Norditropin. They are available only by prescription and administered by injection. The Pituitary Gland and the Hypothalamus:The pituitary gland, recognized as the master gland, produces several hormones that manage the functions of other glands. It is located in the middle of the skull underneath the part of the brain called the hypothalamus. The pituitary gland secretes its hormones in response to a chemical message from the hypothalamus, the part of the brain to which it is linked. The pituitary gland has two separate parts, the anterior front lobe and the posterior rear lobe. The anterior lobe produces six major hormones, one for the production of breast milk, two for reproduction, one for thyroid function, one for adrenal function, and one is somatotropin, which influences growth and metabolism chemical and physical processes to preserve life. The hypothalamus stimulates the hormone release from the anterior pituitary; these hormones then act elsewhere in the body. When the pituitary gland is removed or destroyed, hormone secretion is gone. When one or more hormones are lost, this is known as Hypopituitarism; when the pituitary gland is entirely removed or destroyed and all hormone secretion is lost, this is referred to as Panhypopituitarism. Growth hormone somatotropin is frequently the first hormone to be lost or reduced in pituitary and hypothalamic disorders. Adult Growth Hormone Deficiency:Adult Growth Hormone Deficiency is a condition in adults caused by the low or lack of secretion of somatotropin by the anterior pituitary gland. Somatotropin is another name for growth hormone. Hormones are chemical messages produced by special cells in glands and other organs of the body. A...
