Human body is a complex
system, it secrets many different hormones for different functions. Each and
every hormone is important for the proper functioning of body. Growth hormone
is one of the many hormones which body secretes for itself. It is really important
to understand the nature and functions of this hormone. Let’s try to know that what is a growth hormone.
All hormones are protein
in nature, so growth hormones are also protein, which consist of 190 amino
acids. There are special cells called as “Somatotrophs”, which secret these
hormones. There is pituitary gland in human brain and somatotrophs are part of
this pituitary gland. These cells not just synthesize growth hormone but store
and secrete them in the body. Interior
pituitary gland secrets these hormone and they play a very important role in
human body. The basic areas which are affected by human growth hormones are
growth and metabolism.
What is a growth hormone is not a new
question. The scientists tried hard to know that what is the basic factor which
effects human growth, and after many years of researches, they concluded that
growth hormones are the key factors in human growth. In some cases when human
body fails to produce these hormones, they are injected in the body.
Recombinant DNA technology is the latest technology, which help us to produce
growth hormones. These artificial growth hormones are used as drug to treat
growth disorders in young children. Not just the children, but adults can also
be treated with these hormones when they have deficiency of growth hormones.
Human growth hormone is
considered as complex hormone and many functions of this hormone are still
unknown. I hope now it is bit clear that what
is growth hormone. Many books are available on the topic, if you want to read
