Introduction to Terpenes: These substances constitute the largest group of secondary plant products and show some of the properties of lipids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names.

During an inflammatory response, both the level and Introduction. These hormone like substances increase or lower the blood pressure, inflammation and pain when tissues are injured. They are divided into 4 series, the A, B, E, and Falpha series, which differ in the structure of the characteristic 5-membered ring. The classification based on molecular targets is the most useful classification for medicinal chemists. These hormones are lipophilic in nature and are derivatives of cholesterol (except T 3 and T 4). Eicosanoids interact with cells and are involved in several bodily processes, including inflammation and blood clotting. My article from last week focused on the key components of the endocrine system.Following the same idea, I thought it would be ideal to do a follow up article on the classification of hormones and even mention some of their functions along the way..

Every prostaglandin contains 20 carbon atoms, including a 5-carbon ring. CLASSIFICATION OF PROSTANOID RECEPTORS 207 in 1967 who, using the same approach, demonstrated that, although the classification proposed by Ahlquist was essentially correct, it was an oversimplification and one of Ahlquist's receptors, the fl-adrenoceptor, could be further divided into two subtypes, termed and 132.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are a drug class FDA-approved for use as antipyretic, anti-inflammatory, and analgesic agents. NSAIDs reduce fever via a different means - namely, by reducing hypothalamic prostaglandin synthesis that otherwise leads to elevated prostaglandin E2 levels.

Paracetamol (Acetaminophen): - Paracetamol is one of the analgesics which is also known as acetaminophen or APAP. The tone for modern day discovery and use of NSAIDs was set with the discovery of aspirin. Article includes descriptions, uses, drug interactions, and side effects. Within these two major classes of lipids, there are several specific types of lipids important to life, including fatty acids, triglycerides, glycerophospholipids, sphingolipids, and steroids.
