Any multimeric complex connected to a microtubule.

Any microtubule that is part of a mitotic or meiotic spindle; anchored at one spindle pole.

The formation from simpler components of glycerolipids, any lipid with a glycerol backbone.

The chemical reactions involving phosphatidylcholines, any of a class of glycerophospholipids in which the phosphatidyl group is esterified to the hydroxyl group of choline. They are important constituents of cell membranes.

negative regulation of nitric oxide biosynthesis

Any process that stops, prevents or reduces the rate of the formation from simpler components of nitric oxide.

The chemical reactions involving phosphatidic acid, any derivative of glycerol phosphate in which both the remaining hydroxyl groups of the glycerol moiety are esterified with fatty acids.

The formation from simpler components of glycerophospholipids, any derivative of glycerophosphate that contains at least one O-acyl, O-alkyl, or O-alkenyl group attached to the glycerol residue.

The formation from simpler components of glycosylceramides, any compound formed by the replacement of the glycosidic hydroxyl group of a cyclic form of a monosaccharide (or derivative) by a ceramide group.

The breakdown into simpler components of glycosylceramides, any compound formed by the replacement of the glycosidic hydroxyl group of a cyclic form of a monosaccharide (or derivative) by a ceramide group.

The breakdown into simpler components of glycosphingolipid, a compound with residues of sphingoid and at least one monosaccharide.

The pathway along which proteins and other substances are moved around and out of the cell. After synthesis on the ribosomes of the endoplasmic reticulum (ER), completed polypeptide chains are moved to the Golgi complex and subsequently sorted to various destinations. Proteins synthesized and sorted in the secretory pathway include not only those that are secreted from the cell but also enzymes and other resident proteins in the lumen of the ER, Golgi, and lysosomes as well as integral proteins in the membranes of these organelles and the plasma membrane.
