Lipid-derived Compounds in the Human Body01:31

Lipid-derived Compounds in the Human Body

6.0K
Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various  biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

Structure and Nomenclature of Epoxides

7.6K
Cyclic ethers are heterocyclic compounds with an oxygen atom in the ring along with carbon atoms. They are named depending on the number of carbon atoms present in their ring system. Cyclic ethers with a three-membered ring system are called “oxirane”, four-membered ring systems as “oxetane”, five-membered ring systems as “oxolane”, and six-membered ring systems as “oxane”. The cyclic structure of these rings imposes angle strain, and this strain...

Stability of Conjugated Dienes01:28

Stability of Conjugated Dienes

4.0K
Introduction
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.

Inflammatory Response I: Vascular and Cellular01:30

Inflammatory Response I: Vascular and Cellular

15.3K
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Types of Hormones01:21

Types of Hormones

6.1K
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...

Preparation of Epoxides03:00

Preparation of Epoxides

8.9K
Overview
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Pharmacology

Background:

  • Eicosanoids are signaling molecules derived from 20-carbon polyunsaturated fatty acids.
  • Synthesis occurs via cyclooxygenase (COX), lipoxygenase (LOX), and cytochrome P450 (cytP450) pathways.
  • Arachidonic acid is the primary substrate for eicosanoid production.

Purpose of the Study:

  • To elucidate eicosanoid synthesis pathways, receptor interactions, and physiological functions.
  • To explore the involvement of eicosanoids in various diseases.
  • To review inhibitors of eicosanoid synthesis and action for therapeutic potential.

Main Methods:

  • Review of established biochemical pathways for eicosanoid synthesis.
  • Analysis of eicosanoid receptor signaling mechanisms.
  • Examination of the roles of eicosanoids in physiological and pathological contexts.

Main Results:

  • Eicosanoids include prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs).
  • These molecules act locally via G-protein coupled and nuclear receptors, exhibiting pleiotropic effects on inflammation and immunity.
  • Eicosanoids are implicated in vascular, renal, gastrointestinal, and reproductive systems, as well as inflammatory diseases and cancer.

Conclusions:

  • Eicosanoids are critical mediators in both health and disease.
  • Targeting eicosanoid pathways offers therapeutic strategies, particularly for inflammatory conditions.
  • Further research into eicosanoid signaling can unlock new treatment avenues.
