The chemical reactions involving glutathione, the tripeptide glutamylcysteinylglycine, which acts as a coenzyme for some enzymes and as an antioxidant in the protection of sulfhydryl groups in enzymes and other proteins; it has a specific role in the reduction of hydrogen peroxide (H2O2) and oxidized ascorbate, and it participates in the gamma-glutamyl cycle.

Catalysis of the reaction: donor + H2O2 = oxidized donor + 2 H2O.

Catalysis of the reaction: 2 glutathione + H2O2 = oxidized glutathione + 2 H2O.

Catalysis of the reaction: S-adenosyl-L-methionine + phenylethanolamine = S-adenosyl-L-homocysteine + N-methylphenylethanolamine.

Catalysis of the reaction: CTP + phosphatidate = diphosphate + CDP-diacylglycerol.

Catalysis of the reaction: phosphatidylcholine + a sterol = a sterol ester + 1-acylglycerophosphocholine.

The chemical reactions involving peptidoglycans, any of a class of glycoconjugates found only in bacterial cell walls and consisting of strands of glycosaminoglycan cross-linked by oligopeptides to form a huge and rigid network.

The chemical reactions involving compounds containing a single carbon atom.

Catalysis of the reaction: S-adenosyl-L-methionine + phosphatidylethanolamine = S-adenosyl-L-homocysteine + phosphatidyl-N-methylethanolamine.

The formation from simpler components of polysaccharides, polymers of more than 10 monosaccharide residues joined by glycosidic linkages.

Catalysis of the reaction: phosphatidyl-L-serine = phosphatidylethanolamine + CO2.

The breakdown into simpler components of polysaccharides, polymers of more than 10 monosaccharide residues joined by glycosidic linkages.

The chemical reactions involving coenzymes, any of various nonprotein organic cofactors that are required, in addition to an enzyme and a substrate, for an enzymatic reaction to proceed.

The chemical reactions involving lipoic acid, 1,2-dithiolane-3-pentanoic acid, a coenzyme involved in oxidative decarboxylation of keto acids.

A light-dependent catabolic process occurring concomitantly with photosynthesis in plants (especially C3 plants) whereby dioxygen (O2) is consumed and carbon dioxide (CO2) is evolved. The substrate is glycolate formed in large quantities in chloroplasts from 2-phosphoglycolate generated from ribulose 1,5-bisphosphate by the action of ribulose-bisphosphate carboxylase; the glycolate enters the peroxisomes where it is converted by glycolate oxidase to glyoxylate which undergoes transamination to glycine. This then passes into the mitochondria where it is decarboxylated forming one molecule of serine for every two molecules of glycine. This pathway also exists in photosynthetic bacteria.
