hydrogen Hydrogen: The first chemical element in the periodic table with atomic symbol H, and atomic number 1. Protium (atomic weight 1) is by far the most common hydrogen isotope. Hydrogen also exists as the stable isotope DEUTERIUM (atomic weight 2) and the radioactive isotope TRITIUM (atomic weight 3). Hydrogen forms into a diatomic molecule at room temperature and appears as a highly flammable colorless and odorless gas.. dihydrogen : An elemental molecule consisting of two hydrogens joined by a single bond. | 2.02 | 1 | 0 | elemental hydrogen; elemental molecule; gas molecular entity | antioxidant; electron donor; food packaging gas; fuel; human metabolite |
vinyl ether vinyl ether: major descriptor (65-85); on-line search VINYL COMPOUNDS (66-85); Index Medicus search VINYL ETHER (65-85) | 2.93 | 4 | 0 | ether | |
linoleic acid Linoleic Acid: A doubly unsaturated fatty acid, occurring widely in plant glycosides. It is an essential fatty acid in mammalian nutrition and is used in the biosynthesis of prostaglandins and cell membranes. (From Stedman, 26th ed). linoleic acid : An octadecadienoic acid in which the two double bonds are at positions 9 and 12 and have Z (cis) stereochemistry. | 2.08 | 1 | 0 | octadecadienoic acid; omega-6 fatty acid | algal metabolite; Daphnia galeata metabolite; plant metabolite |
alpha-linolenic acid linolenic acid : A two-membered subclass of octadecatrienoic acid comprising the (9Z,12Z,15Z)- and (6Z,9Z,12Z)-isomers. Linolenic acids are nutrients essential to the formation of prostaglandins and are also used in making paints and synthetic resins.. linolenate : A polyunsaturated fatty acid anion obtained by deprotonation of the carboxy group of either alpha- or gamma-linolenic acid. | 2.43 | 2 | 0 | linolenic acid; omega-3 fatty acid | micronutrient; mouse metabolite; nutraceutical |

15-hydroperoxy-5,8,11,13-eicosatetraenoic acid 15-hydroperoxy-5,8,11,13-eicosatetraenoic acid: RN given refers to cpd without isomeric designation; (S-(E,Z,Z,Z))-isomer caused dose-dependent constriction of cat coronary arteries; structure in first source. 15-HPETE : A HPETE that consists of (5Z,8Z,11Z,13E)-icosatetraenoic acid in which the hydroperoxy group is located at position 15. | 1.99 | 1 | 0 | HPETE | human xenobiotic metabolite |
chlorophyll a Chlorophyll: Porphyrin derivatives containing magnesium that act to convert light energy in photosynthetic organisms.. chlorophyll : A family of magnesium porphyrins, defined by the presence of a fifth ring beyond the four pyrrole-like rings. The rings can have various side chains which usually include a long phytol chain. | 1.99 | 1 | 0 | chlorophyll; methyl ester | cofactor |
etheroleic acid etheroleic acid: a divinyl ether; structure given in first source. etheroleic acid : A divinyl ether fatty acid that is (9Z,11E,14E)-nonadeca-9,11,14-trienoic acid in which the methylene group at position 10 has been replaced by oxygen. | 2.69 | 3 | 0 | divinyl ether fatty acid; long-chain fatty acid | |
