Peptide hormones play crucial roles in regulating various physiological processes. Let’s explore some notable peptide hormones,
CJC-1295, Thyrotropin-Releasing Hormone, Glucagon, Calcitonin, Vasopressin & Hepcidin Proteins

Best describe as Growth hormone (GH) or simply human growth hormone (HGH) are known as somatotropin which help stimulate cell growth and reproduction, which leads to increased cell regeneration in human bodies. Some Researchers hold that GH is essential in regular human development and vice versa. While

s a peptide hormone, its mitogen that is specifically present in certain types of cells.

Among the many forms of human growth hormone found in the medicinal and pharmaceutical worlds. The most common is the recombinant form that’s given as a prescription drug to children with growth problems and deficiency. HGH has also been banned by many major sports and athletics committees due to the role it plays in the human body. It can be used as an anabolic steroid to elicit performance advantages in athletes.

Growth hormone Function

Knowing that Growth hormones mainly has anabolic effects to regulate fat

muscle on tissues. Which means it tends to help build ups.
Common example of its function is children with low growth spurts -

known to have a deficiency in human growth hormone.

But, the function of HGH doesn’t end here. It is also known to help improve calcium retention in cells, which leads to an increase in bone strength. Furthermore, it can help improve and increase muscle mass through a process known as hypertrophy. In conjunction with this. HGH also boosts protein synthesis in the body.

Human growth hormone also acts to grow all the organs in the body, with the exception of the brain. It also reduces the way the liver takes in glucose, and can play a key role in homeostasis. Another well-known function of this growth hormone is the way it acts to stimulate the immune system.

Mechanism/Interactions

HGH stimulates height in children by at least two different mechanisms. The first is that GH uses some of its effects to connect with receptors on target cells, activating something known as the MAPK/ERK pathway. By doing this, growth hormone can help divide and multiple chondrocytes of cartilage. This is important because most polypeptide hormones can’t penetrate cell membranes due to them not being fat-soluble. Secondly, growth hormone helps to induce the production of IGF-1 (insulin-like growth factor 1). It does this through the JAK-STAT signaling pathway. It interacts with the liver, which is the main place where IGF-1 is produced. IGF-1 is known to help stimulate growth in many different tissues.

Structure

Human growth hormone is primarily comprised of a protein weighing 22, 124 daltons. It contains 191 amino acids, and the structure can be described as having four helices. These helices are essential for interacting with the GH receptor, which helps elicit its various functions. A closer look at the structure of GH reveals that it is homologous to prolactin and chorionic somatomammotropin.
There are many growth hormones present in different species, but only human growth hormone and old world monkey growth hormone will have any effect on the HGH receptor.
