The pituitary gland is a small gland that sits in the sella turcica (‘Turkish saddle’), a bony hollow in the base of the skull, underneath the brain and behind the bridge of the nose. The pituitary gland has two main parts, the anterior pituitary gland and the posterior pituitary gland. The gland is attached to a part of the brain (the hypothalamus) that controls its activity. The anterior pituitary gland is connected to the brain by short blood vessels. The posterior pituitary gland is actually part of the brain and it secretes hormones directly into the bloodstream under the command of the brain.

Chemical nature of hormones secreted by the pituitary gland
The hormones secreted by the pituitary gland are primarily protein hormones. These hormones are composed of long chains of amino acids, making them proteins.
Protein hormones
Protein hormones are made up of specific sequences of amino acids that determine their structure and function. Examples of protein hormones secreted by the pituitary gland include growth hormone, prolactin, follicle-stimulating hormone, luteinizing hormone, and thyroid-stimulating hormone.
Function of protein hormones
Protein hormones act by binding to specific receptors on target cells, triggering a series of biochemical reactions within the cell. These reactions ultimately lead to changes in cellular activity and physiological processes in the body.
Complex compounds of proteins and carbohydrates
Although some hormones may contain carbohydrates in addition to proteins, the primary chemical nature of hormones secreted by the pituitary gland is protein-based. These hormones may undergo post-translational modifications, such as glycosylation, where carbohydrates are added to the protein structure.
In conclusion, the hormones secreted by the pituitary gland are primarily protein hormones, composed of long chains of amino acids. While some hormones may contain carbohydrates as well, the main chemical nature of these hormones is protein-based.
