Popular questions
  1. What is mannitol used for?

    In foods, E421 mannitol is used as a low‑calorie sweetener, bulking agent, and humectant/stabilizer (common in sugar‑free gum, candies, and baked goods); it’s also a pharmaceutical excipient. Medically, IV mannitol is an osmotic diuretic to reduce intracranial and intraocular pressure and promote diuresis.

  2. How mannitol works?

    As a food ingredient, it’s poorly absorbed so it provides fewer calories and a low glycemic response, with a mild cooling taste. As a medicine, it acts osmotically—filtered by the kidneys and minimally reabsorbed—raising plasma and tubular fluid osmolality to draw water from tissues and increase urine output, lowering brain/eye pressure.

  3. How does mannitol work?

    It works osmotically when given IV, increasing blood and renal filtrate osmolality so water moves from tissues into the circulation and then into urine, reducing intracranial and intraocular pressure. In foods, its limited absorption yields a lower-calorie, low‑glycemic sweetening effect.

  4. Is mannitol safe for dogs?

    Mannitol isn’t known to be acutely toxic to dogs like xylitol, but ingestion can cause diarrhea and gas, and large amounts may lead to dehydration or electrolyte imbalances. Therapeutic IV mannitol should only be used by a veterinarian; consult your vet especially for dogs with kidney or heart disease.

  5. Is mannitol salt agar selective or differential?

    Both: the high salt concentration makes it selective for staphylococci, and mannitol with phenol red makes it differential by turning yellow when mannitol‑fermenting organisms (e.g., many S. aureus) produce acid.

  1. What is tagatose made from?

    Industrial tagatose is typically made by hydrolyzing lactose (from whey) to galactose and then enzymatically isomerizing the galactose to D‑tagatose; newer processes can start from plant sugars using microbial enzymes.

  2. What is tagatose sweetener?

    Tagatose (E963) is a low‑calorie rare sugar used as a bulk sweetener, about 90% as sweet as sucrose and providing roughly 1.5 kcal/g with a low glycemic impact.

  3. Below is the open-chain of the monosaccharide d-tagatose, which is the ketohexose?

    D‑Tagatose is a ketohexose (the C‑4 epimer of D‑fructose) whose open‑chain form has a ketone at C‑2 and cyclizes in solution to furanose or pyranose rings.

  4. Below is the open-chain structure of the monosaccharide d-tagatose, which is a ketohexose. like most monosaccharides, it has more than one chiral carbon. select all of the chiral carbon atoms.?

    In the open‑chain D‑tagatose, the chiral centers are C‑3, C‑4, and C‑5.

  5. Haworth projection tagatose which carbon supplies the oh?

    For ring formation, the OH on C‑5 typically attacks C‑2 to give the furanose, while the OH on C‑6 can attack C‑2 to give the pyranose.
