Is histamine acidic or basic? Histamine storage in mast cell granules is dependent onacidic pH. A hallmark feature of mast cells of all locations and species is their high content of histamine, a bioactive amine with profound effects on various parameters of inflammation. Does milk have histamine?
Why are carboxyl groups considered acidic? Explain why the pH of 1.0M hydrochloric acid is 1.0M while that of 1.0M ethanoic acid is 5.0. Explain why the pH decreases when SO_3 is dissolved in water. An acid, HA, is 90% unionized. Is this a strong or weak acid? Explain. ...
One study showed Abl1 to bind in-vitro to the carboxyl-terminal regulatory domain of p53 and to prevent its dissociation with the DNA complex [24]. Another study reported a protective role of Abl1 in neutralizing the inhibitory effects of Mdm2 on p53 [25]. In fact, Abl1 phosphorylates ...
环境监测大题(Environmental monitoring is a big problem).doc,环境监测大题(Environmental monitoring is a big problem) One, two different methods for determining the first type of pollutants in water are described respectively. Determination of mercury;
The serine–arginine SR region (which includes H3) has been previously identified as engaging in interaction with a structured acidic helix in Nsp3 in the model coronavirus MHV, consistent with an electrostatic helical interaction97,98. Recent NMR data also show excellent agreement with our results...
What ions makes urine more acidic or basic? a. Hydrogen ion b. Bicarbonate ion c. Both of them d. None Low pH in the stomach is achieved by what process? a. Parietal cells secrete HCl into the lumen of the stomach. b. Chief ce...
Two arginines within the basic region near the IM bind acidic cardiolipin head groups by an electrostatic mechanism, and are necessary for bacterial cell growth and barrier function even at low levels of PhoPQ signaling. Full-length PbgA oligomers are tetrameric in solution. The PbgA-globular ...
For C_4H_{11}N write the relative acidity or basis. What is strong about a strong acid. What is common to all acids? Which of the following would form acidic, basic or neutral solutions: NH_4F, NH_4CN, NH_4CH_3COO, NH_4Cl, Ba(CH_3COO)_2, NaCN, CaSO_4? Which of the foll...
The amino acids are arranged in three types: polar and acidic, polar and basic, and non-polar and neutral. The solubility of the protein is determined...Become a member and unlock all Study Answers Start today. Try it n...
it is not surprising that two of the three DGBp1-interactors identified here were ribosome-associated proteins. The large subunit of ribosomes has a lateral protrusion or ribosomal stalk composed of acidic proteins P0, P1, and P2 and the plant-specific P3 (RPP3). P-protein complex is though...
