d-alpha tocopherol Vitamin E: A generic descriptor for all TOCOPHEROLS and TOCOTRIENOLS that exhibit ALPHA-TOCOPHEROL activity. By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of ISOPRENOIDS.. tocopherol : A collective name for a group of closely related lipids that contain a chroman-6-ol nucleus substituted at position 2 by a methyl group and by a saturated hydrocarbon chain consisting of three isoprenoid units. They are designated as alpha-, beta-, gamma-, and delta-tocopherol depending on the number and position of additional methyl substituents on the aromatic ring. Tocopherols occur in vegetable oils and vegetable oil products, almost exclusively with R,R,R configuration. Tocotrienols differ from tocopherols only in having three double bonds in the hydrocarbon chain.. vitamin E : Any member of a group of fat-soluble chromanols that exhibit biological activity against vitamin E deficiency. The vitamers in this class consists of a chroman-6-ol core which is substituted at position 2 by a methyl group and (also at position 2) either a saturated or a triply-unsaturated hydrocarbon chain consisting of three isoprenoid units. The major function of vitamin E is to act as a natural antioxidant by scavenging free radicals and molecular oxygen.. (R,R,R)-alpha-tocopherol : An alpha-tocopherol that has R,R,R configuration. The naturally occurring stereoisomer of alpha-tocopherol, it is found particularly in sunflower and olive oils. | 2.13 | 1 | 0 | alpha-tocopherol | algal metabolite; antiatherogenic agent; anticoagulant; antioxidant; antiviral agent; EC 2.7.11.13 (protein kinase C) inhibitor; immunomodulator; micronutrient; nutraceutical; plant metabolite |

chloroprene Chloroprene: Toxic, possibly carcinogenic, monomer of neoprene, a synthetic rubber; causes damage to skin, lungs, CNS, kidneys, liver, blood cells and fetuses. Synonym: 2-chlorobutadiene. | 2.04 | 1 | 0 | chloroolefin | |
gamma-tocopherol gamma-Tocopherol: A natural tocopherol with less antioxidant activity than ALPHA-TOCOPHEROL. It exhibits antioxidant activity by virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus. As in BETA-TOCOPHEROL, it also has three methyl groups on the 6-chromanol nucleus but at different sites.. gamma-tocopherol : A tocopherol in which the chroman-6-ol core is substituted by methyl groups at positions 7 and 8. It is found particularly in maize (corn) oil and soya bean (soybean) oils. | 2.13 | 1 | 0 | tocopherol; vitamin E | algal metabolite; food antioxidant; plant metabolite |

vitamin k 1 Vitamin K 1: A family of phylloquinones that contains a ring of 2-methyl-1,4-naphthoquinone and an isoprenoid side chain. Members of this group of vitamin K 1 have only one double bond on the proximal isoprene unit. Rich sources of vitamin K 1 include green plants, algae, and photosynthetic bacteria. Vitamin K1 has antihemorrhagic and prothrombogenic activity.. phylloquinone : A member of the class of phylloquinones that consists of 1,4-naphthoquinone having methyl and phytyl groups at positions 2 and 3 respectively. The parent of the class of phylloquinones. | 2.13 | 1 | 0 | phylloquinones; vitamin K | cofactor; human metabolite; plant 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. | 2.73 | 3 | 0 | chlorophyll; methyl ester | cofactor |
