Compounds (38)

CompoundDescription
hydronium ion
CobaltA trace element that is a component of vitamin B12. It has the atomic symbol Co, atomic number 27, and atomic weight 58.93. It is used in nuclear weapons, alloys, and pigments. Deficiency in animals leads to anemia; its excess in humans can lead to erythrocytosis.
Succinate
Ammonium
CopperA heavy metal trace element with the atomic symbol Cu, atomic number 29, and atomic weight 63.55.
Carbon DioxideA colorless, odorless gas that can be formed by the body and is necessary for the respiration cycle of plants and animals.
dimercaprolAn anti-gas warfare agent that is effective against Lewisite (dichloro(2-chlorovinyl)arsine) and formerly known as British Anti-Lewisite or BAL. It acts as a chelating agent and is used in the treatment of arsenic, gold, and other heavy metal poisoning.
ZincA metallic element of atomic number 30 and atomic weight 65.38. It is a necessary trace element in the diet, forming an essential part of many enzymes, and playing an important role in protein synthesis and in cell division. Zinc deficiency is associated with ANEMIA, short stature, HYPOGONADISM, impaired WOUND HEALING, and geophagia. It is known by the symbol Zn.
Orthophosphate
Aspartate
adenosine diphosphateAdenosine 5'-(trihydrogen diphosphate). An adenine nucleotide containing two phosphate groups esterified to the sugar moiety at the 5'-position.
boric acid
potassiumAn element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
MagnesiumA metallic element that has the atomic symbol Mg, atomic number 12, and atomic weight 24.31. It is important for the activity of many enzymes, especially those involved in OXIDATIVE PHOSPHORYLATION.
SodiumA member of the alkali group of metals. It has the atomic symbol Na, atomic number 11, and atomic weight 23.
WaterA clear, odorless, tasteless liquid that is essential for most animal and plant life and is an excellent solvent for many substances. The chemical formula is hydrogen oxide (H2O). (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
succinyl-coenzyme A
iodoacetamideAn alkylating sulfhydryl reagent. Its actions are similar to those of iodoacetate.
Pyruvic AcidAn intermediate compound in the metabolism of carbohydrates, proteins, and fats. In thiamine deficiency, its oxidation is retarded and it accumulates in the tissues, especially in nervous structures. (From Stedman, 26th ed)
NADPNicotinamide adenine dinucleotide phosphate. A coenzyme composed of ribosylnicotinamide 5'-phosphate (NMN) coupled by pyrophosphate linkage to the 5'-phosphate adenosine 2',5'-bisphosphate. It serves as an electron carrier in a number of reactions, being alternately oxidized (NADP+) and reduced (NADPH). (Dorland, 27th ed)

alpha-Ketoglutarate
OxaloacetateAn anionic form of oxaloacetic acid.
diethyl pyrocarbonatePreservative for wines, soft drinks, and fruit juices and a gentle esterifying agent.
ethylmaleimideA sulfhydryl reagent that is widely used in experimental biochemical studies.
2,6-pyridine dicarboxylate
Edetic AcidA chelating agent that sequesters a variety of polyvalent cations such as CALCIUM. It is used in pharmaceutical manufacturing and as a food additive.
aspartic semialdehydeRN given refers to cpd without isomeric designation
maleate
glutamate
adenosine triphosphateAn adenine nucleotide containing three phosphate groups esterified to the sugar moiety. In addition to its crucial roles in metabolism adenosine triphosphate is a neurotransmitter.
CysteineA thiol-containing non-essential amino acid that is oxidized to form CYSTINE.
bromopyruvate
hydroxylamineA colorless inorganic compound (HONH2) used in organic synthesis and as a reducing agent, due to its ability to donate nitric oxide.
