Popis: Manganese(IV) oxide is suitable for use in batteries. It is widely used for the selective oxidation of allylic and benzylic alcohols to aldehydes or ketones, as a co-oxidant in combination with 1,4-benzoquinone and in the allylic oxidation of olefins catalyzed by Palladium(II)­ acetate. It acts a reagent for oxidations. It is the source of manganese and all its compounds, largely used in manufacturing of manganese steel, for making amethyst glass, decolorizing glass, painting on porcelain, faience and majolica. The precipitate is used in electrotechnics, pigments, browning gun barrels, drier for paints and varnishes, printing and dyeing textiles.

Popis: Carbonic anhydrases (CAs) are members of a large family of zinc metalloenzymes responsible for catalyzing the reversible hydration of carbon dioxide. CAs show extensive diversity in their distribution and subcellular localisation. They are involved in a variety of biological processes, including calcification, bone resorption, respiration, acid-base balance and the formation of aqueous humor, saliva, gastric juice and cerebrospinal fluid. CA X also referred to as Carbonic anhydrase-related protein X (CA-RP X) or Cerebral protein 15, is a member of the carbonic anhydrase family that lacks two of the three Zn-binding motifs essential for carbonic anhydrase activity. For this reason, CA X does not exhibit catalytic activity. It is expressed primarily in brain and kidney and may play a role in brain development.

Popis: RuBisCO catalyzes two reactions: the carboxylation of D-ribulose 1,5-bisphosphate, the primary event in carbon dioxide fixation, as well as the oxidative fragmentation of the pentose substrate in the photorespiration process. Both reactions occur simultaneously and in competition at the same active site.Sequence similarities: Belongs to the RuBisCO large chain family. Type I subfamily.Post-translational modifications: The disulfide bond which can form between Cys-247 in the large chain dimeric partners within the hexadecamer appears to be associated with oxidative stress and protein turnover (By similarity). The disulfide bonds reported in 1RBO may be the result of oxidation during crystallization.

Popis: CSAD is a 493 amino acid protein that exists as a homodimer and belongs to the group II decarboxylase family. CSAD catalyses the conversion of 3-sulfino-L-alanine to hypotaurine and carbon dioxide, binds pyridoxal phosphate as a cofactor and undergoes alternative splicing to produce three isoforms. The gene encoding CSAD maps to human chromosome 12, which encodes over 1,100 genes and comprises approximately 4.5% of the human genome. Chromosome 12 is associated with a variety of diseases and afflictions, including hypochondrogenesis, achondrogenesis, Kniest dysplasia, Noonan syndrome and trisomy 12p, which causes facial developmental defects and seizure disorders.

Popis: MP EcoChrom™ SILICA is used as a suspending and thickening agent in pharmaceutical.A silica-based aerogel was used in the Stardust spacecraft to collect extraterrestrial particles. Silica is also used in the extraction of DNA and RNA due to its ability to bind to the nucleic acids under the presence of chaotropes. As hydrophobic silica it is used as a defoamer component. In hydrated form, it is used in toothpaste as a hard abrasive to remove tooth plaque. SiO2 has a number of distinct crystalline forms (polymorphs) in addition to amorphous forms. In the majority of silicates, the Si atom shows tetrahedral coordination, with 4 oxygen atoms surrounding a central Si atom.

MP EcoChrom™ Silica, the chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with the chemical formula SiO2 with a mean pore size of 60Å and particles size of 200-500μm. MP silica are free of particles outside the standard range. The irregular shape of MP Silica permits the easy packing of column permeability and plate number. They allow easy switching from one sieve cut to another, offering an easy way to change the chromatographic methods. It has been known for its hardness since ancient times. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms.
