  2. Lysozyme - Wikipedia

    en.wikipedia.org/wiki/Lysozyme

    In humans, the C-type lysozyme enzyme is encoded by the LYZ gene. [3] [4] Hen egg white lysozyme is thermally stable, with a melting point reaching up to 72 °C at pH 5.0. [5] However, lysozyme in human milk loses activity very quickly at that temperature. [6] Hen egg white lysozyme maintains its activity in a large range of pH (6–9). [7]

  3. Oxygen-evolving complex - Wikipedia

    en.wikipedia.org/wiki/Oxygen-evolving_complex

    Photons trapped by photosystem II move the system from state S 0 to S 1 to S 2 to S 3 and finally to S 4. S 4 reacts with water producing free oxygen: 2 H 2 O → O 2 + 4 H + + 4 e −. This conversion resets the catalyst to the S 0 state. The active site of the OEC consists of a cluster of manganese and calcium with the formula Mn 4 Ca 1 O x ...

    en.wikipedia.org/wiki/Water_purification

    Station for complex water treatment SKO-10K. One of the first steps in most conventional water purification processes is the addition of chemicals to assist in the removal of particles suspended in water. Particles can be inorganic such as clay and silt or organic such as algae, bacteria, viruses, protozoa and natural organic matter.

  5. Water treatment - Wikipedia

    en.wikipedia.org/wiki/Water_treatment

    Dalecarlia Water Treatment Plant, Washington, D.C. Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.

  6. Acid hydrolase - Wikipedia

    en.wikipedia.org/wiki/Acid_hydrolase

    An acid hydrolase is an enzyme that works best at acidic pHs.It is commonly located in lysosomes, which are acidic on the inside.Acid hydrolases may be nucleases, proteases, glycosidases, lipases, phosphatases, sulfatases and phospholipases and make up the approximately 50 degradative enzymes of the lysosome that break apart biological matter.

  7. Carbonic anhydrase - Wikipedia

    en.wikipedia.org/wiki/Carbonic_anhydrase

    The HCO 3 − and H + are ideal for buffering pH in the blood and tissues because the pKa is close to the physiological pH = 7.2 – 7.6. Since HCO 3 − and H + are regulated in the kidneys and plasma carbon dioxide is regulated in the lungs, both actions in the kidneys and lungs are important to maintain the stability of blood pH.

  8. Industrial water treatment - Wikipedia

    en.wikipedia.org/wiki/Industrial_water_treatment

    Water treatment therefore should remove the dissolved oxygen and maintain the boiler water with the appropriate pH and alkalinity levels. Without effective water treatment, a cooling water system can suffer from scale formation, corrosion and fouling and may become a breeding ground for harmful bacteria.

  9. Lysine - Wikipedia

    en.wikipedia.org/wiki/Lysine

    Lysine ball and stick model spinning. Lysine (symbol Lys or K) [2] is an α-amino acid that is a precursor to many proteins.Lysine contains an α-amino group (which is in the protonated −NH + 3 form when the lysine is dissolved in water at physiological pH), an α-carboxylic acid group (which is in the deprotonated −COO − form when the lysine is dissolved in water at physiological pH ...
