  3. Liposome - Wikipedia

    en.wikipedia.org/wiki/Liposome

    Liposome. Scheme of a liposome formed by phospholipids in an aqueous solution. Liposomes are composite structures made of phospholipids and may contain small amounts of other molecules. Though liposomes can vary in size from low micrometer range to tens of micrometers, unilamellar liposomes, as pictured here, are typically in the lower size ...

  4. Nicotinamide mononucleotide - Wikipedia

    en.wikipedia.org/wiki/Nicotinamide_mononucleotide

    Nicotinamide mononucleotide (" NMN " and " β-NMN ") is a nucleotide derived from ribose, nicotinamide, nicotinamide riboside and niacin. [ 1] In humans, several enzymes use NMN to generate nicotinamide adenine dinucleotide (NADH). [ 1] In mice, it has been proposed that NMN is absorbed via the small intestine within 10 minutes of oral uptake ...

    Tocotrienol. The vitamin E family comprises four tocotrienols (alpha, beta, gamma, delta) and four tocopherols (alpha, beta, gamma, delta). The critical chemical structural difference between tocotrienols and tocopherols is that tocotrienols have unsaturated isoprenoid side chains with three carbon-carbon double bonds versus saturated side ...

  9. Chemistry of ascorbic acid - Wikipedia

    en.wikipedia.org/wiki/Chemistry_of_ascorbic_acid

    Ascorbic acid is a furan -based lactone of 2-ketogluconic acid. It contains an adjacent enediol adjacent to the carbonyl. This −C (OH)=C (OH)−C (=O)− structural pattern is characteristic of reductones, and increases the acidity of one of the enol hydroxyl groups.
