Polyhydroxy steroids

Another 2011 publication Polyhydroxy Fullerenes (Fullerols or Fullerenols): Beneficial Effects on Growth and Lifespan in Diverse Biological Models indicates that fullerenes can extend the lifespans of certain more primitive organisms.   The publication reports “ Recent toxicological studies on carbon nanomaterials, including fullerenes, have led to concerns about their safety. Functionalized fullerenes, such as polyhydroxy fullerenes (PHF, fullerols, or fullerenols), have attracted particular attention due to their water solubility and toxicity. Here, we report surprisingly beneficial and/or specific effects of PHF on model organisms representing four kingdoms, including the green algae Pseudokirchneriella subcapitata , the plant Arabidopsis thaliana , the fungus Aspergillus niger , and the invertebrate Ceriodaphnia dubia . The results showed that PHF had no acute or chronic negative effects on the freshwater organisms. Conversely, PHF could surprisingly increase the algal culture d ensity over controls at higher concentrations (., 72% increase by 1 and 5 mg/L of PHF) and extend the lifespan and stimulate the reproduction of Daphnia (. about 38% by 20 mg/L of PHF). We also show that at certain PHF concentrations fungal growth can be enhanced and Arabidopsis thaliana seedlings exhibit longer hypocotyls, while other complex physiological processes remain unaffected. These findings may open new research fields in the potential applications of PHF, ., in biofuel production and aquaculture. These results will form the basis of further research into the mechanisms of growth stimulation and life extension by PHF.”

The diverse structures and uncertain metabolic fate of phenolic compounds following digestion prevent understanding about their potential health effects. Specifically, because the presumed antioxidant role of polyphenols in vivo cannot be established, the US Food and Drug Administration (FDA) issued labeling guidance to manufacturers that polyphenols cannot be mentioned as antioxidant nutrients unless physiological evidence exists to verify such a qualification and a DRI value has been established. [56] [58] Further, because purported health claims for specific polyphenol-enriched foods remain unproven, [59] health statements about polyphenols on product labels are prohibited by the FDA. [56]

    A) The two compounds can be differentiated by their mass spectra because they will have molecular ion peaks at different m/z.   B) 1-Hexene will show an absorption at 1650 cm –1 but cyclohexane will not.   C) Both cyclohexane and 1-hexene will show C–H absorptions at about 2950 cm –1 .   D) Statements B (1-Hexene will show an absorption at 1650 cm –1 but cyclohexane will not) and C (Both cyclohexane and 1-hexene will show C–H absorptions at about 2950 cm –1 ) are both true.   E) Statements A (The two compounds can be differentiated by their mass spectra because they will have molecular ions at different masses), B (1-Hexene will show an absorption at 1650 cm –1 but cyclohexane will not), and (Both cyclohexane and 1- hexene will show C–H absorptions at about 2950 cm –1 ) are all true.
