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

Reaction: SLCO1B3 transports ALB:(GCCA, TCCA) from extracellular region to cytosol (Homo sapiens)
A molecule of extracellular glycocholate or taurocholate is transported into the cytosol, mediated by OATP-8 (SLCO1B3) in the plasma membrane. Glycocholate and taurocholate exist in the blood as complexes with serum albumin, and their uptake by OATP-8 must involve disruption of these complexes, but the molecular mechanism coupling disruption and uptake is unknown. In the body, OATP-8 is expressed on th

Pathway: SLC-mediated transmembrane transport (Homo sapiens)
Proteins with transporting functions can be roughly classified into 3 categories: ATP-powered pumps, ion channels, and transporters. Pumps utilize the energy released by ATP hydrolysis to power the movement of the substrates across the membrane, against their electrochemical gradient. Channels at the open state can transfer the substrates (ions or water) down their electrochemical gradient, at an extre

Pathway: Transport of vitamins, nucleosides, and related molecules (Homo sapiens)
This pathway groups the processes mediated by SLC transporters, by which vitamins and cofactors, as well as nucleosides, nucleotides, nucleobases, and related molecules cross lipid bilayer membranes

Pathway: Bile acid and bile salt metabolism (Homo sapiens)
In a healthy adult human, about 500 mg of cholesterol is converted to bile salts daily. Newly synthesized bile salts are secreted into the bile and released into the small intestine where they emulsify dietary fats (Russell 2003). About 95% of the bile salts in the intestine are recovered and returned to the liver (Kullak-Ublick et al. 2004; Trauner and Boyer 2002). The major pathway for bile salt synt

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: Recycling of bile acids and salts (Homo sapiens)
Of the 20-40 grams of bile salts released daily by the liver, all but approximately 0.5 grams are re ... 8 (OATPA - SLCO1A2, OATPC - SLCO1B1, and OATP-8 - SLCO1B3). Once returned to the hepatocyte cytosol, bile acids (generated in the intestine by the action of bacteria on secreted bile salts) are activated by conjugation with coenzyme A, then coupled to glycine or taurine, regenerating bile salts for ...

Pathway: Transport of organic anions (Homo sapiens)
Organic anion transporting polypeptides (OATPs) are membrane transport proteins that mediate the sodium-independent transport of a wide range of amphipathic organic compounds including bile salts, steroid conjugates, thyroid hormones, anionic oligopeptides and numerous drugs (Hagenbuch B and Meier PJ, 2004)
