• magnesium
  • and the other one, called polyphosphate body PPB, is composed of phosphorus and oxygen plus magnesium, calcium, and aluminum. (duhnnae.com)
  • Magnesium is the eighth most abundant element in the Earth's crust and the fourth most common element in the Earth (after iron, oxygen and silicon), making up 13% of the planet's mass and a large fraction of the planet's mantle. (wikipedia.org)
  • It tarnishes slightly when exposed to air, although, unlike the other alkaline earth metals, an oxygen-free environment is unnecessary for storage because magnesium is protected by a thin layer of oxide that is fairly impermeable and difficult to remove. (wikipedia.org)
  • ions
  • However, depending on the degree of polymerization, ammonium polyphosphate can act as a chelating agent to keep certain metal ions dissolved in solution. (wikipedia.org)
  • hydrogen
  • A lone pair of electrons on an oxygen atom can be donated to a hydrogen ion (proton) or a metal ion in a typical Lewis acid-Lewis base interaction. (wikipedia.org)
  • citation needed] L. plantarum is a Gram-positive-aerotolerant bacteria that grows at 15 °C (59 °F) but not at 45 °C (113 °F), and produces both isomers of lactic acid (D and L). This species and related lactobacilli are unusual in that they can respire oxygen but have no respiratory chain or cytochromes[citation needed] - the consumed oxygen ultimately ends up as hydrogen peroxide. (wikipedia.org)
  • Organic groups can substitute on the oxygen for the OH group, or replace a hydrogen on the amine group. (wikipedia.org)
  • carbon
  • The filters can contain many different medias including carbon ion exchange chelating and oxygen removal resins as well as special combinations. (apswater.com)
  • Here you will find carbon particulate Ion Exchange polyphosphate oxygen removal and many other different types of filter cartridges. (apswater.com)
  • In the gas phase, the release of non-flammable carbon dioxide helps to dilute the oxygen of the air and flammable decomposition products of the material that is burning. (wikipedia.org)
  • This high yield was observed in spite of 70% more carbon dioxide being fixed than could be accounted for as biomass, indicating the excretion of a carbon intermediate, which is not observed in Thermithiobacillus tepidarius, which was isolated from the same location at the Roman Baths in Bath, also by enrichment culture on thiosulfate as the sole electron donor and molecular oxygen as the terminal electron acceptor. (wikipedia.org)
  • calcium
  • At the end of the review, a hypothesis is discussed in view of synthetic biology applications that states polyphosphate and calcium-rich organelles have endosymbiotic origins from ancient protocells that metabolized polyphosphate. (biomedcentral.com)
  • group
  • B. an amount of an organic chelator which is in a weight ratio of from about 0.025:1 to about 20:1 to said available oxygen, the said chelator being selected from the group consisting of aminotri(methylphosphonic acid), ethylenediaminetetra(methylphosphonic acid), diethylenetriamine penta(methylphosphonic acid and the alkali metal salts thereof. (google.es)
  • organic
  • 3. The composition of claim 2 wherein the weight ratio of organic chelator to available oxygen provided by the surface active peroxyacid bleach is from about 0.025:1 to about 20:1. (google.es)
  • represents
  • An oxyanion or oxoanion is an ion with the generic formula A xOz− y (where A represents a chemical element and O represents an oxygen atom). (wikipedia.org)
