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: Neuronal System (Homo sapiens)
The human brain contains at least 100 billion neurons, each with the ability to influence many other cells. Clearly, highly sophisticated and efficient mechanisms are needed to enable communication among this astronomical number of elements. This communication occurs across synapses, the functional connection between neurons. Synapses can be divided into two general classes: electrical synapses and che

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: Neurotransmitter Release Cycle (Homo sapiens)
Neurotransmitter is stored in the synaptic vesicle in the pre-synaptic terminal prior to its release in the synaptic cleft upon depolarization of the pre-synaptic membrane. The release of the neurotransmitter is a multi-step process that is controlled by electrical signals passing through the axons in form of action potential. Neurotransmitters include glutamate, acetylcholine, nor-epinephrine, dopami

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: 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: Transmission across Chemical Synapses (Homo sapiens)
Chemical synapses are specialized junctions that are used for communication between neurons, neurons and muscle or gland cells. The synapse involves a pre-synaptic neuron and a post-synaptic neuron, muscle cell or glad cell. The pre and the post-synaptic cell are separated by a gap of 20nm called the synaptic cleft. The signals pass in a unidirection from pre-synaptic to post-synaptic. The pre-synapti

Pathway: Synthesis of PC (Homo sapiens)
De novo (Kennedy pathway) synthesis of phosphatidylcholine (PC) involves phosphorylation of choline (Cho) to phosphocholine (PCho) followed by condensing with cytidine triphosphate (CTP) to form CDP-choline (CDP-Cho). Diacylglycerol (DAG) and CDP-ETA together then form PC. Alternatively, PC is formed when phosphatidylethanolamine (PE) is methylated by phosphatidylethanolamine N-methyltransfera

Pathway: Acetylcholine Neurotransmitter Release Cycle (Homo sapiens)
Acetylcholine neurotransmitter release cycle involves syntheis of choline, loading of clathrin scultpted synaptic vesicles, docking and priming of the acetyl choline loaded synaptic vesicles and then release of acetylcholine. This cycle occurs in neurons of central nervous system (CNS), peripheral, autonomic and somatic nervous system. In the CNS, the acetylcholine is released by the presynaptic neuron
