A type of late endosome in which regions of the limiting endosomal membrane invaginate to form internal vesicles; membrane proteins that enter the internal vesicles are sequestered from the cytoplasm.

The whole of the physical, chemical, and biochemical processes carried out by living organisms to break down ingested lipids into components that may be easily absorbed and directed into metabolism.

Catalysis of the reaction: aspartate + H2O + O2 = oxaloacetate + NH3 + H2O2.

The breakdown into simpler components of lipids, as carried out by individual cells.

Catalysis of the hydrolysis of mannosyl compounds, substances containing a group derived from a cyclic form of mannose or a mannose derivative.

A closed structure, found only in eukaryotic cells, that is completely surrounded by unit membrane and contains liquid material.

Catalysis of the hydrolysis of the terminal alpha-D-mannose residues in oligo-mannose oligosaccharides.

The lipid bilayer surrounding the vacuole and separating its contents from the cytoplasm of the cell.

Catalysis of the hydrolysis of galactosyl compounds, substances containing a group derived from a cyclic form of galactose or a galactose derivative.

The volume enclosed within the vacuolar membrane.

Catalysis of the hydrolysis of glucosyl compounds, substances containing a group derived from a cyclic form of glucose or a glucose derivative.

A double-membrane bound vesicle in which endogenous cellular material is sequestered; known as autophagosome in yeast.

Catalysis of the hydrolysis of trehalose or a trehalose derivative.

A small, membrane-bounded organelle that uses dioxygen (O2) to oxidize organic molecules; contains some enzymes that produce and others that degrade hydrogen peroxide (H2O2).

The breakdown into simpler components of polysaccharides, polymers of more than 10 monosaccharide residues joined by glycosidic linkages, as carried out by individual cells.
