  • substance
  • Storing blood for longer periods means you have to actually freeze it, but freezing damages cellular structures unless a protective substance such as glycerol, an ice recrystallization inhibitor, is used. (medgadget.com)
  • potassium
  • With the help of our senior chemistry technician, Esther Ette, we made a video of the reaction between glycerol and potassium manganate (VII). (bris.ac.uk)
  • A twist on this experiment is to place methane bubbles above the glycerol potassium manganate (VII) mixture in the cap of a bottle. (bris.ac.uk)
  • Molecules can either move across the membrane by passive transport which does not require energy, such as simple diffusion, or active transport which does require energy, such as a sodium-potassium pump. (differencebetween.net)
  • The corrosive, alkaline lye (sodium hydroxide, although you can also use potassium hydroxide) breaks the glycerol (a heavy alcohol) off those chains and the methanol (a light alcohol) in turn takes the place of the glycerol, leaving shorter, lighter, more combustible molecules.

  • prevents
  • The new research, published today in the print edition of the Journal of Physical Chemistry B , reveals how glycerol prevents ice crystals from forming in water as the solution is cooled to -35°C, with important implications for improving cryoprotectants used in fertility treatments and food storage. (leeds.ac.uk)
  • water
  • It is used to disinfect water and will also catch fire when glycerol is added to it. (bris.ac.uk)
  • This makes it difficult for a molecule of water to escape to become a gas. (prezi.com)
  • Water molecule will cluster around slightly charged parts of the solute and separates the molecules (dissolves). (prezi.com)
  • Water molecules stick to each other creating surface tension on the water surface. (prezi.com)
  • Transport of water in the xylem relies on water molecules sticking to each other as they are pulled up the xylem in the transpiration stream. (prezi.com)
  • Condesation - forms disaccharide molecule & glycosidic bond forms between them - water given off. (prezi.com)
  • The SANDALS instrument allowed the team to see, at the molecular level, that the water and glycerol segregated into clusters. (leeds.ac.uk)
  • Instead, the glycerol molecules encapsulated the water, preventing the formation of an icy network. (leeds.ac.uk)
  • oxygen
  • Glycerol has been known since its discovery in 1779 by Carl Scheele, a scientist more famous for his discovery of oxygen. (bris.ac.uk)
  • different
  • The molecules that need to enter and leave a mitochondria compared with a chloroplast for instance, will be different at times because the organelles have different functions. (differencebetween.net)
  • alcohol
  • Glycerol has a primary alcohol at each end, with a secondary alcohol in the middle. (bris.ac.uk)
  • Glycerol is a triol containing two primary alcohols (RCH 2 OH) and one secondary alcohol (R 2 CHOH) and its unambiguous IUPAC name is given as propane-1,2,3-triol. (bris.ac.uk)
  • either
  • The synthesis of monoglyceride (MG) either by glycerol esterification or trans-esterification, is an attractive option to transform this biomass derived compound into fine chemicals. (omicsonline.org)
  • important
  • Cryoprotectant molecules, including glycerol, play an important role in protecting cells and tissues from harmful ice crystals when they are cooled to sub-zero temperatures during freeze storage. (leeds.ac.uk)
  • type
  • Organelle plasma membranes still have selective-permeability and carefully control what substances pass into and out of an organelle, but the type of molecules needed by the organelle will differ. (differencebetween.net)
  • main
  • During biodiesel synthesis by oil or fat trans-esterification, glycerol is obtained as the main co-product, representing 10% of the biodiesel production. (omicsonline.org)
