Catalysis of the reaction: alpha-lactose = beta-(1->6)-galactobiose.

Catalysis of the transfer of an acyl group from one position to another within a single molecule.

The chemical reactions and pathways resulting in the formation of coenzyme B (7-mercaptoheptanoylthreonine phosphate), a coenzyme involved in the utilization of methane by methanogenic prokaryotes.

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.

Catalysis of the reaction: 3 H+ + methyl-1,4-benzoquinone + NADPH = methyl-1,4-benzoquinol + NADP.

Catalysis of an oxidation-reduction (redox) reaction in which NADH or NADPH acts as a hydrogen or electron donor and reduces a quinone or a similar acceptor molecule.

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

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

The chemical reactions and pathways resulting in the breakdown into fatty acids and monoglycerides of lipids in the small intestine. Lipids are broken down by lipases released by the pancreas.

The chemical reactions and pathways resulting in the breakdown of lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent.
