CompoundDescription
diphosphoric acid
hydronium ion
NADH
Carbon DioxideA colorless, odorless gas that can be formed by the body and is necessary for the respiration cycle of plants and animals.
adenosine diphosphateAdenosine 5'-(trihydrogen diphosphate). An adenine nucleotide containing two phosphate groups esterified to the sugar moiety at the 5'-position.
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)
OxygenAn element with atomic symbol O, atomic number 8, and atomic weight [15.99903; 15.99977]. It is the most abundant element on earth and essential for respiration.
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)
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)
isopentenyl pyrophosphatesubstrate for isopentenyl pyrophosphate isomerase; RN given refers to unlabeled cpd; a nonpeptide mycobacterial antigen that stimulates gamma delta T cells
farnesyl pyrophosphatea sesquiterpene that dimerizes to SQUALENE; RN given refers to cpd without isomeric designation
geranyl diphosphatestructure in first source
formic acidRN given refers to parent cpd
22,23-dihydroergosterolRN given refers to (3beta)-isomer
2,3-oxidosqualenean oxidized derivative of SQUALENE that can fold in several ways: chair-boat-chair-boat to LANOSTEROL; chair-chair-chair-boat to dammarane; or all chair to hopane and on to cycloartenol; RN given refers to (all-Z)-isomer
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.
Cytidine MonophosphateCytidine (dihydrogen phosphate). A cytosine nucleotide containing one phosphate group esterified to the sugar moiety in the 2', 3' or 5' position.
Cytidine TriphosphateCytidine 5'-(tetrahydrogen triphosphate). A cytosine nucleotide containing three phosphate groups esterified to the sugar moiety.
4-hydroxy-3-methylbut-2-enyl pyrophosphatestructure in first source
2-C-methyl-D-erythritol 2,4-cyclodiphosphate
1-deoxy-D-xylulose 5-phosphate
s-adenosylmethioninePhysiologic methyl radical donor involved in enzymatic transmethylation reactions and present in all living organisms. It possesses anti-inflammatory activity and has been used in treatment of chronic liver disease. (From Merck, 11th ed)
4-diphosphocytidyl-2-c-methylerythritolstructure in first source
cycloartenolfound in chlorophyll-containing plants; minor descriptor (76-83); on-line & Index Medicus search PHYTOSTEROLS (76-83); RN given refers to (3beta)-isomer
