The subunits forming the inner ring of the core complex of a proteasome located in the nucleus of a cell.

The proteasome core subcomplex that constitutes the two inner rings of the cytosolic proteasome core complex.

A multisubunit complex located in the cytosol of a cell, which caps one or both ends of the proteasome core complex. This complex recognizes, unfolds ubiquitinated proteins and translocates them to the proteasome core complex.

OBSOLETE. The core complex of a proteasome located in the endoplasmic reticulum of a cell.

The core complex of a proteasome located in the nucleus of a cell.

The subunits forming the outer ring of the core complex of a proteasome located in the nucleus of a cell.

The core complex of a proteasome located in the cytosol of a cell.

The proteasome core subcomplex that constitutes the two outer rings of the cytosolic proteasome core complex.

OBSOLETE. The subunits forming the outer ring of the core complex of a proteasome located in the endoplasmic reticulum of a cell.

The chemical reactions and pathways resulting in the formation of diacylglycerol, a glyceride in which any two of the R groups (positions not specified) are acyl groups while the remaining R group can be either H or an alkyl group.

The chemical reactions and pathways involving any 1,2-diacyl-sn-glycero-3-phosphocholine, the compounds most commonly designated lecithin.

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

The phosphatidylcholine biosynthetic process that begins with the phosphorylation of choline and ends with the combination of CDP-choline with diacylglycerol to form phosphatidylcholine.

The chemical reactions and pathways resulting in the formation of phosphatidylserines, any of a class of glycerophospholipids in which the phosphatidyl group is esterified to the hydroxyl group of L-serine.

The chemical reactions and pathways resulting in the breakdown of phosphatidylserines, any of a class of glycerophospholipids in which the phosphatidyl group is esterified to the hydroxyl group of L-serine.

The chemical reactions and pathways involving liposaccharide.

The chemical reactions and pathways resulting in the formation of platelet activating factor, 1-O-alkyl-2-acetyl-sn-glycerol 3-phosphocholine, where alkyl = hexadecyl or octadecyl. Platelet activating factor is an inflammatory mediator released from a variety of cells in response to various stimuli.

The chemical reactions and pathways resulting in the formation of ether lipids, lipids that contain (normally) one lipid alcohol in ether linkage to one of the carbon atoms (normally C-1) of glycerol.

The chemical reactions and pathways involving 3-keto-sphinganine, a derivative of sphinganine with a ketone group at C3. It is an intermediate in the synthesis of sphingosine.
