Types of Hormones

Types of Hormones

Hormones can be classified into three main types based on their chemical structures: steroids, peptides, and amines. Their actions are mediated by the specific receptors they bind to on target cells.

Types of Hormones

Types of Hormones

Hormones are classified into four main groups: steroids, eicosanoids, amino acid-based derivatives, and peptide hormones.
Steroids and eicosanoids fall under the category of lipid-soluble hormones. Steroids are derived from cholesterol and feature four interconnected carbon rings with variable side chains. Notable examples include estradiol from ovaries and testosterone from testes, exemplifying the critical roles of these lipid-soluble hormones in reproductive physiology. Eicosanoids, derived...

Hormonal Regulation

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Hormonal Regulation

Hormonal Regulation

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Plant Hormones

Plant Hormones

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Power

Power

The concept of work involves force and displacement; meanwhile, the work-energy theorem relates the net work done on a body to the difference in its kinetic energy, calculated between two points on its trajectory. While none of these quantities or relations involves time explicitly, we know that the time available to accomplish work is often just as important as the amount of work itself. For example, sprinters in a race may have achieved the same velocity at the finish, therefore,...

Area of Science:

Endocrinology
Neuroscience
Molecular Biology

Background:

Pro-opiomelanocortin (POMC) is a precursor for vital hormones and neuropeptides.
POMC processing generates diverse peptides with critical physiological roles.
Variability in POMC processing affects tissue-specific functions.

Purpose of the Study:

To review the variability in POMC-derived peptides across tissues.
To discuss challenges in quantitatively measuring POMC precursors and fragments.
To explore the impact of processing abnormalities on pathophysiology.

Main Methods:

Review of existing literature on POMC processing pathways.
Discussion of the role of pro-hormone convertases (PCs) in tissue-specific processing.
Analysis of cellular mechanisms governing regulated secretion of POMC peptides.

Main Results:

POMC processing is highly variable, influenced by tissue-specific pro-hormone convertases (PCs).
Inaccurate measurement of POMC precursors and fragments hinders understanding of pathophysiology.
Disrupted POMC processing in the pituitary affects the hypothalamic-pituitary-adrenal axis; in the hypothalamus, it impacts appetite and energy homeostasis.

Conclusions:

A comprehensive understanding of POMC processing, including peptide ratios and bioactivity, is essential.
Further research is needed to correlate POMC gene expression with bioactive peptide release.
Accurate quantitative analysis of POMC processing is critical for advancing research in endocrinology and neuroscience.
