Nitrite is rapidly protonated to form HONO in acidic conditions23. We observed that incubation of isolated cell wall material and intact sacculi with acidified nitrite released 70–80% of GAC in a water-soluble form (Fig. 1b, d). In contrast, chemically N-acetylated GAS cell wall or sacc...
However, pH 2 is not representative of the pH that CPPs may be exposed to when in contact with cells, either pH 7.2 outside the plasma membrane, or pH between 6.5 and 4.5 while inside acidic endosomes. In order to establish the relative hydrophobicities of d(X)TAT peptides at these ...
(e.g. concentrated sulfuric acid), methanesulfonic acid (e.g. anhydrous methanesulfonic acid) and the like); an acid anhydride such as acetic anhydride or trifluoromethane-sulfonic anhydride; P2O5 in methanesulfonic acid; a phosphorous-based halogenating agent such as P(O)Cl3, PCl3 or PCl5; ...
This invention relates to the production of acetic anhydride by thermal dehydration of acetic acid by means of gaseous catalysts and has for its object to ... from the aforementioned heating, in the presence of a volatile basic nitrogen compound 55 added before said products are below a temperat...
Which compound is more basic, triethylamine or aniline? Does the following reaction proceed as written? What is the mechanism for the reaction between 3-methyl-2-pentene and HCl? Write the structure of the product that would form from the following reaction. Phen...
2 or Cl) is reacted with acetic anhydride into a novel compound of formula III; (2) this compound is solvolyzed under an acidic or basic condition into a second novel compound of formula IV; (3) this compound is condensed with 3,4-dihydro-2 H-pyran in the presence of an acid ...
