Cholesterol Metabolism
Cholesterol is an essential sterol that modulates membrane fluidity and serves as a precursor for bile acids, steroid hormones, and vitamin D.
Eicosanoids
Eicosanoids are signaling molecules derived from arachidonic acid that mediate inflammation, fever, pain, blood clotting, and smooth muscle contraction.
Lipid Structure and Classification
Lipids are a diverse group of hydrophobic or amphipathic molecules that serve as energy stores, structural components of membranes, and signaling molecules.
Lipoproteins and Lipid Transport
Lipoproteins are complexes of lipids and proteins that transport hydrophobic lipids through the aqueous environment of the bloodstream.
Membrane Lipids
Membrane lipids form the structural foundation of biological membranes, providing a selective barrier that defines cellular and organellar boundaries.
Phospholipid and Sphingolipid Metabolism
Phospholipids and sphingolipids are the major structural lipids of membranes, and their synthesis, degradation, and remodeling are tightly regulated.
