  2. Raspberry ketone - Wikipedia

    en.wikipedia.org/wiki/Raspberry_ketone

    Little is known about the long-term safety of raspberry ketone supplements, [15] [16] especially since little research has been done with humans. [17] Toxicological models indicate a potential for cardiotoxic effects, as well as effects on reproduction and development. [15]

  3. Butanone - Wikipedia

    en.wikipedia.org/wiki/Butanone

    Butanone, also known as methyl ethyl ketone (MEK) or ethyl methyl ketone, [a] is an organic compound with the formula CH 3 C(O)CH 2 CH 3. This colorless liquid ketone has a sharp, sweet odor reminiscent of acetone .

  4. 4-Hydroxynonenal - Wikipedia

    en.wikipedia.org/wiki/4-Hydroxynonenal

    4-Hydroxynonenal, or 4-hydroxy-2E-nonenal or 4-hydroxy-2-nonenal or 4-HNE or HNE, (C 9 H 16 O 2), is an α,β-unsaturated hydroxyalkenal that is produced by lipid peroxidation in cells. 4-HNE is the primary α,β-unsaturated hydroxyalkenal formed in this process. It is a colorless oil.

  8. Mannich reaction - Wikipedia

    en.wikipedia.org/wiki/Mannich_reaction

    In organic chemistry, the Mannich reaction is a three-component organic reaction that involves the amino alkylation of an acidic proton next to a carbonyl (C=O) functional group by formaldehyde (H−CHO) and a primary or secondary amine (−NH 2) or ammonia (NH 3). [1] The final product is a β-amino-carbonyl compound also known as a Mannich base.

  9. 3,4-dihydroxy-2-butanone-4-phosphate synthase - Wikipedia

    en.wikipedia.org/wiki/3,4-dihydroxy-2-butanone-4...

    The enzyme 3,4-dihydroxy-2-butanone 4-phosphate synthase (DHBP synthase) (RibB) EC 4.1.99.12 catalyses the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate, the latter serving as the biosynthetic precursor for the xylene ring of riboflavin. [1]
