Hormones are chemical substances that act as molecules of messengers that flow into the bloodstream. Hormones carry chemical messages from the glands where they are produced to cells in various parts of the human body. These chemical messages help to activate or disable cellular processes that regulate stress, appetite, growth, sleep cycle, blood sugar, sexual desire, and sexual function.
The importance of hormones in the proper functioning of the human body is great. They control the function of organs and affect their growth, reproduction and sexual characteristics.
In addition, hormones also influence how the human body stores and utilizes energy and regulates fluid volume and blood sugar and salt levels. Therefore, a small amount of the hormone can trigger an important response in the human body.
The various chemical hormones released within the human body control and regulate the functions of many organs. The release of hormones into the bloodstream occurs in the endocrine glands.
Hormones act as a signal to the blood. The blood transfers them to various organs and tissues of the human body. After reaching the target area, hormones bind to the receptors. Once the process is complete, the hormones, in turn, transmit the message that causes the organ or tissue to perform a specific function.
The following are some important hormonal functions:
Hormones may be regulated by glands and organs, by negative reactions, or by other hormones. Hormones that regulate the release of other hormones are described as tropical hormones, which are released into the anterior pituitary brain.
Many hormone levels are affected in the body during pregnancy. Several hormones play a major role during pregnancy such as Oestrogen, Progesterone, chorionic gonadotropin hormone (hCG), and Human placental lactogen (hPL).
Hormones may be classified into chemicals such as proteins or steroids. All hormones in the human body, with the exception of sex hormones and those from the adrenal cortex, are proteins or proteins.
The key components of hormones are:
Hormones are made up of a variety of chemicals but are divided into three categories:
Some hormones, such as serotonin and dopamine, also act as neurotransmitters, which are chemicals that carry messages between nerve cells in the brain and from neurons to muscles.
Although there are several types of hormones in the human body, they are mainly divided into three categories according to their chemical structure. These are –
Lipid-based hormones are primarily found in cholesterol, and they share similarities in their structure. Steroid hormones are lipid hormones that are essential for the human body, and they are chemicals called ketones or alcohol. Examples of steroid hormones are cortisol and aldosterone.
These hormone levels are derived from the amino acids, tyrosine and tryptophan. Examples of hormones such as norepinephrine and epinephrine. The medulla portion of the adrenal glands produces these. In addition, the pineal gland in the brain produces melatonin, which regulates the sleep cycle.
The structure of the peptide hormone is similar to that of the polypeptide chain (amino acid chain). A well-known example of the peptide hormone is pancreatic insulin.

Chemical hormones are responsible for regulating and regulating the activity of certain cells and organs. These hormones are produced by the pituitary glands known as endocrine glands.
Hormones are divided into two types, namely: Peptide hormones and steroid hormones.
1- Diabetes, 2 - Osteoporosis. 3 - Hyperthyroidism.
Hormones are made of proteins or steroids.
The hormone released by the adrenal glands is called Epinephrine. Also called adrenaline.
The hormone produced by the pineal gland is Melatonin. It regulates the sleep cycle.
