Compounds (20)

CompoundDescription
hydronium ion
squaleneA natural 30-carbon triterpene.
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.
cycloleucalenolstructure
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)

22,23-dihydrobrassicasterol
24-methylene lophenol
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
24-methylenecholesterolRN given refers to (3beta)-isomer; structure
campesterolRN refers to (3beta,24R)-isomer; structure
