Chemical structure of lipid A as found in E. coli [1]. Lipid A is a lipid component of an endotoxin held responsible for the toxicity of gram-negative bacteria.It is the innermost of the three regions of the lipopolysaccharide (LPS), also called endotoxin molecule, and its hydrophobic nature allows it to anchor the LPS to the outer membrane.

Crotonic acid has 4 carbons, is included in croton oil, and is a trans-2-mono-unsaturated fatty acid.C 3 H 5 CO 2 H, IUPAC organization name (E)-but-2-enoic acid, trans-but-2-enoic acid, numerical representation 4:1, n-1, molecular weight 86.09, melting point 72–74 °C, boiling point 180–181 °C, specific gravity 1.027.
Mammals lack the ability to introduce double bonds in fatty acids beyond carbon 9 and 10, hence the omega−6 linoleic acid (18:2n−6; LA) and the omega−3 alpha-linolenic acid (18:3n−3; ALA) are essential for humans in the diet. However, humans can convert both LA and ALA to fatty acids with longer carbon chains and a larger number of ...
A lipoprotein is a biochemical assembly whose primary function is to transport hydrophobic lipid (also known as fat) molecules in water, as in blood plasma or other extracellular fluids. They consist of a triglyceride and cholesterol center, surrounded by a phospholipid outer shell, with the hydrophilic portions oriented outward toward the ...
Lipoic acid (LA), also known as α-lipoic acid, alpha-lipoic acid (ALA) and thioctic acid, is an organosulfur compound derived from caprylic acid (octanoic acid). [3] ALA, which is made in animals normally, is essential for aerobic metabolism .
Lipid metabolism is the synthesis and degradation of lipids in cells, involving the breakdown and storage of fats for energy and the synthesis of structural and ...
Lipid peroxidation, or lipid oxidation, is a complex chemical process that leads to oxidative degradation of lipids, [1] resulting in the formation of peroxide and hydroperoxide derivatives. [2] It occurs when free radicals , specifically reactive oxygen species (ROS), interact with lipids within cell membranes , typically polyunsaturated fatty ...
Palmitoylethanolamide (PEA) is an endogenous fatty acid amide, and lipid modulator. [2] A main target of PEA is proposed to be the peroxisome proliferator-activated receptor alpha (PPAR-α). [3] [4] PEA also has affinity to cannabinoid-like G-coupled receptors GPR55 and GPR119. [5]
