EOG86X1RK GO:0005576 21/48 extracellular region cellular_component "The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite." [GOC:go_curators] EOG86X1RK GO:0006629 21/48 lipid metabolic process biological_process "The chemical reactions and pathways involving lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. Includes fatty acids; neutral fats, other fatty-acid esters, and soaps; long-chain (fatty) alcohols and waxes; sphingoids and other long-chain bases; glycolipids, phospholipids and sphingolipids; and carotenes, polyprenols, sterols, terpenes and other isoprenoids." [GOC:ma] EOG86X1RK GO:0016787 15/48 hydrolase activity molecular_function "Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3." [ISBN:0198506732] EOG86X1RK GO:0003824 4/48 catalytic activity molecular_function "Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic." [ISBN:0198506732] EOG86X1RK GO:0004806 2/48 triglyceride lipase activity molecular_function "Catalysis of the reaction: triacylglycerol + H2O = diacylglycerol + a carboxylate." [EC:3.1.1.3]
