Pathway: Metabolism (Homo sapiens)
Metabolic processes in human cells generate energy through the oxidation of molecules consumed in the diet and mediate the synthesis of diverse essential molecules not taken in the diet as well as the inactivation and elimination of toxic ones generated endogenously or present in the extracellular environment. The processes of energy metabolism can be classified into two groups according to whether the

Pathway: Phospholipid metabolism (Homo sapiens)
Phospholipids contain a polar head group and two long-chain fatty acyl moieties, one of which is generally unsaturated. The head group is a glycerol or serine phosphate attached to a polar group such as choline. These molecules are a major constituent of cellular membranes, where their diverse structures and asymmetric distributions play major roles in determining membrane properties (Dowhan 1997). The

Pathway: Glycerophospholipid biosynthesis (Homo sapiens)
Glycerophospholipids are important structural and functional components of biological membranes and constituents of serum lipoproteins and the pulmonary surfactant. In addition, glycerophospholipids act as precursors of lipid mediators such as platelet-activating factor and eicosanoids. Cellular membranes contains a distinct composition of various glycerophospholipids such as phosphatidic acid (PA),

Pathway: Fatty acid, triacylglycerol, and ketone body metabolism (Homo sapiens)
The reactions involved in the metabolism of fatty acids and of the triacylglycerols and ketone bodies derived from them form a closely interrelated, coordinately regulated module that plays a central role in human energy metabolism

Pathway: Metabolism of lipids and lipoproteins (Homo sapiens)
Lipids are hydrophobic but otherwise chemically diverse molecules that play a wide variety of roles in human biology. They include ketone bodies, fatty acids, triacylglycerols, phospholipids and sphingolipids, eicosanoids, cholesterol, bile salts, steroid hormones, and fat-soluble vitamins. They function as a major source of energy (fatty acids, triacylglycerols, and ketone bodies), are major constitue

Pathway: Triglyceride Biosynthesis (Homo sapiens)
The overall process of triglyceride (triacylglycerol) biosynthesis consists of four biochemical pathways: fatty acyl-CoA biosynthesis, conversion of fatty acyl-CoA to phosphatidic acid, conversion of phosphatidic acid to diacylglycerol, and conversion fo diacylglycerol to triacylglycerol

Pathway: Synthesis of PA (Homo sapiens)
In the de novo synthesis of phosphatidic acid (PA), lysophosphatidic acid (LPA) is initially formed by the esterification of sn-1 by glycerol 3-phosphate acyltransferase (GPAT) from glycerol 3-phosphate (G3P). Next, LPA is converted to PA by a LPA acyltransferase (AGPAT, also known as LPAAT). In addition to this, PA is also formed when phosphatidylcholine (PC) is hydrolyzed by phospholip

Reaction: 1-acyl LPA is acylated to PA by AGPAT (LPAAT) (Homo sapiens)
At the endoplasmic reticulum (ER) membrane, 1-acyl-lysophosphatidic acid (LPA) is acylated to phosphatidic acid (PA) by the enzymes 1-acyl-sn-glycerol-3-phosphate acyltransferases (AGPAT1 through 11), and lysophosphatidylcholine acyltransferase (LPCAT1) (Aguado and Campbell 1998). See recent review by Agarwal (2012, in press). AGPAT1, 2, 3 and LPCAT1 have been characterized biochemically
