A urea hydantoin that is found in URINE and PLANTS and is used in dermatological preparations.
An enzyme that catalyzes the conversion of urate and unidentified products. It is a copper protein. The initial products decompose to form allantoin. EC 1.7.3.3.
Compounds based on imidazolidine dione. Some derivatives are ANTICONVULSANTS.
Ureohydrolases are a class of enzymes that catalyze the hydrolysis of urea into ammonia and carbon dioxide, which can include urease, urease accessory proteins, and other enzymes with similar functions.
Tartronates are salts or esters of tartaric acid, which is a crystalline organic acid found in various fruits and used in certain medications as a stabilizing agent or for treating antimony poisoning.
Amino-substituted glyoxylic acid derivative.
Compounds based on reduced IMIDAZOLES containing a single double bond.
Glyoxylates are organic compounds that are intermediate products in the metabolic pathways responsible for the breakdown and synthesis of various molecules, including amino acids and carbohydrates, and are involved in several biochemical processes such as the glyoxylate cycle.
A compound formed in the liver from ammonia produced by the deamination of amino acids. It is the principal end product of protein catabolism and constitutes about one half of the total urinary solids.
Enzymes that catalyze inversion of the configuration around an asymmetric carbon in a substrate having one (racemase) or more (epimerase) center(s) of asymmetry. (Dorland, 28th ed) EC 5.1.
Amidohydrolases are enzymes that catalyze the hydrolysis of amides and related compounds, playing a crucial role in various biological processes including the breakdown and synthesis of bioactive molecules.
An oxidation product, via XANTHINE OXIDASE, of oxypurines such as XANTHINE and HYPOXANTHINE. It is the final oxidation product of purine catabolism in humans and primates, whereas in most other mammals URATE OXIDASE further oxidizes it to ALLANTOIN.
An enzyme that catalyzes the deamination of guanine to form xanthine. EC 3.5.4.3.
Inorganic compounds that contain nitrogen as an integral part of the molecule.
Agents that affect ION PUMPS; ION CHANNELS; ABC TRANSPORTERS; and other MEMBRANE TRANSPORT PROTEINS.
These enzymes catalyze the elimination of ammonia from amidines with the formation of a double bond. EC 4.3.2.
An element with the atomic symbol N, atomic number 7, and atomic weight [14.00643; 14.00728]. Nitrogen exists as a diatomic gas and makes up about 78% of the earth's atmosphere by volume. It is a constituent of proteins and nucleic acids and found in all living cells.
