EOG8NS5SK GO:0016021 21/70 integral component of membrane cellular_component "The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane." [GOC:dos, GOC:go_curators] EOG8NS5SK GO:0006633 21/70 fatty acid biosynthetic process biological_process "The chemical reactions and pathways resulting in the formation of a fatty acid, any of the aliphatic monocarboxylic acids that can be liberated by hydrolysis from naturally occurring fats and oils. Fatty acids are predominantly straight-chain acids of 4 to 24 carbon atoms, which may be saturated or unsaturated; branched fatty acids and hydroxy fatty acids also occur, and very long chain acids of over 30 carbons are found in waxes."

[GOC:mah] EOG8NS5SK GO:0004768 3/70 stearoyl-CoA 9-desaturase activity molecular_function "Catalysis of the reaction: stearoyl-CoA + 2 ferrocytochrome b5 + O2 + 2 H+ = oleoyl-CoA + 2 ferricytochrome b5 + H2O." [EC:1.14.19.1] EOG8NS5SK GO:0005506 1/70 iron ion binding molecular_function "Interacting selectively and non-covalently with iron (Fe) ions." [GOC:ai] EOG8NS5SK GO:0005783 1/70 endoplasmic reticulum cellular_component "The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached)." [ISBN:0198506732]
