The importance of hormone in the proper functioning of a human body is immense. They control the functions of organs and influence their growth, reproduction and sexual characteristics. Moreover, hormones also affect the way a human body stores and use energy and regulate the volume of fluids as well as the level of sugar and salt in blood. Thus, a small amount of hormone can trigger a significant response in the human body. What are Hormones? Hormones are various chemicals released within a human body that regulate and control the activities of multiple organs. The introduction of hormones to the blood takes places via endocrine glands. What Is the Function of Hormones? Hormones act as a messenger which are released into the blood. Blood transmits them to various organs and tissues of the human body. After reaching a target site, hormones bind to the receptors. Once this process is complete, hormones then transmit the message which causes an organ or tissue to perform a specific action. What are The Properties of Hormones? The significant properties of hormones are –
What Are Hormones Made Of? Hormones are made of a diverse range of chemicals, but they are classified in three classes –
How Many Types of Hormones are There in a Human Body? Even though there are several types of hormones in a human body, they are primarily classified into three categories based on their chemical structure. These are –
Lipid-derived hormones primarily derive from cholesterol, and they share a similarity in terms of their structure. Steroid hormones are the primary lipid hormones in a human body, and chemically they are either ketones or alcohols. Examples of steroid hormones are cortisol and aldosterone.
These classes of hormones originates from amino acids, tyrosine and tryptophan. Example of such hormones is norepinephrine and epinephrine. The medulla section of the adrenal glands produces theses. Moreover, the pineal gland in the brain synthesises melatonin, which controls the sleep cycle.
The structure of the peptide hormone is similar to that of the polypeptide chain (chain of amino acids). A popular example of peptide hormone is insulin produced by the pancreas. Name of hormones and their functions Here is a list of some important hormones and their functions –
Hormones are chemical substances released by various endocrine glands to regulate the functions of various organs of a human body. Additionally, hormones are called chemical messengers because they convey the signal which causes an organ or tissue to perform a definite action.
Hormones are made in different endocrine glands within a human body. Some of the prominent glands are hypothalamus, pituitary, thyroid, pineal, pancreas, adrenal, etc. After synthesising, these hormones are released in the blood.
Human body carries Several types of hormones. However, they are classified into three main groups as per their chemical structure. These are lipid-derived hormones, amino acid-derived hormones, and peptide hormones.
