The chemical reactions and pathways resulting in the breakdown of S-adenosylhomocysteine, forming homocysteine and then methionine.

The chemical reactions and pathways involving triglyceride, any triester of glycerol. The three fatty acid residues may all be the same or differ in any permutation. Triglycerides are important components of plant oils, animal fats and animal plasma lipoproteins.

The chemical reactions and pathways resulting in the formation of phosphatidylcholines, any of a class of glycerophospholipids in which the phosphatidyl group is esterified to the hydroxyl group of choline.

The process in which a methyl group is covalently attached to a molecule.

The chemical reactions and pathways resulting in the breakdown of S-adenosylhomocysteine, forming homocysteine and then methionine.

A chronic inflammatory response to an antigenic stimulus. A chronic inflammatory response persists indefinitely during days, weeks, or months in the life of an individual.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a nutrient stimulus.

The chemical reactions and pathways resulting in the breakdown of S-adenosylhomocysteine, forming homocysteine and then methionine.

The cycle from wakefulness through an orderly succession of sleep states and stages that occurs on an approximately 24 hour rhythm.

The chemical reactions and pathways involving methionine (2-amino-4-(methylthio)butanoic acid), a sulfur-containing, essential amino acid found in peptide linkage in proteins.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level.

A chronic inflammatory response to an antigenic stimulus. A chronic inflammatory response persists indefinitely during days, weeks, or months in the life of an individual.

The chemical reactions and pathways involving methionine (2-amino-4-(methylthio)butanoic acid), a sulfur-containing, essential amino acid found in peptide linkage in proteins.

Any cellular process that results in the specification, formation or maintenance of anisotropic intracellular organization or cell growth patterns.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a nutrient stimulus.

The chemical reactions and pathways involving selenocysteine, an essential component of glutathione peroxidase and some other proteins.

The chemical reactions and pathways resulting in the breakdown of S-adenosylhomocysteine, forming homocysteine and then methionine.

A cyclic series of interconversions involving S-adenosylmethionine, S-adenosyl-L-homocysteine, L-cysteine, and L-methionine. Couples utilization of the methyl group of SAM with recycling of the homocysteinyl group and regeneration of methionine.

The cycle from wakefulness through an orderly succession of sleep states and stages that occurs on an approximately 24 hour rhythm.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

An extracellular matrix lying external to fungal cells. The fungal biofilm matrix consists of polysaccharides, proteins, lipids, and nucleic acids. Fungal biofilms mediate adherence to host tissues, and provide protection from host immune defenses.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins.

A cellular structure consisting of parallel, hexagonally arranged actin tubules, comprising filamentous actin and associated proteins. Actin rod structures are found in diverse organisms, having been observed in spores of Dictyostelium discoideum, Drosophila melanogaster oocytes, as well as in numerous animal cells under stress conditions.

A structure lying external to one or more cells, which provides structural support, biochemical or biomechanical cues for cells or tissues.

A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.

A membrane-bounded intracellular vesicle that arises from the ingestion of particulate material by phagocytosis.
