Overview of Fatty Acid Metabolism01:28

Overview of Fatty Acid Metabolism

32.2K
Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

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,...

Coronary Artery Disease II: Pathophysiology

90
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Membrane Fluidity01:23

Membrane Fluidity

162.2K
Cell membranes are composed of phospholipids, proteins, and carbohydrates loosely attached to one another through chemical interactions. Molecules are generally able to move about in the plane of the membrane, giving the membrane its flexible nature called fluidity. Two other features of the membrane contribute to membrane fluidity: the chemical structure of the phospholipids and the presence of cholesterol in the membrane.

Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

185
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Area of Science:

  • Cardiovascular Biology
  • Lipid Metabolism
  • Endothelial Function

Background:

  • The endothelium maintains circulatory homeostasis by regulating vascular tone and acting as a lipid barrier.
  • Elevated plasma free fatty acids (FFAs) are implicated in atherosclerosis and cardiovascular diseases (CVD).
  • FFAs interact with the endothelium, influencing its function and contributing to disease pathogenesis.

Purpose of the Study:

  • To review the mechanisms by which FFAs impact endothelial function.
  • To elucidate the role of FFAs in the development of endothelial dysfunction in CVD.
  • To highlight potential therapeutic targets within FFA-mediated pathways.

Main Methods:

  • Literature review focusing on FFA-endothelium interactions.
  • Analysis of metabolic pathways linking FFAs to endothelial dysfunction.
  • Synthesis of current understanding of FFA-mediated CVD pathogenesis.

Main Results:

  • FFAs contribute to endothelial dysfunction through mechanisms including altered nitric oxide production, inflammation, oxidative stress, and apoptosis.
  • Dysregulated FFA metabolism is a key factor in the onset of endothelial dysfunction associated with CVD.
  • Several signaling pathways are activated by FFAs, leading to detrimental effects on the endothelium.

Conclusions:

  • FFA-mediated endothelial dysfunction is a critical component in the development of cardiovascular diseases.
  • Targeting FFA metabolic pathways offers a potential strategy for preventing CVD complications.
  • Further research into these pathways may reveal novel therapeutic interventions for cardiovascular health.
