The influence of fatty acids on ileal absorption of water, electrolytes, glucose, and taurocholate was examined in Thirty-Vella fistulas in five mongrel dogs. Fatty acid absorption also was measured. Segments of terminal ileum were perfused at steady state with isotonic electrolyte solutions containing 11.2 mM glucose, 4.5 mM taurocholate, and 0.1-5.0 mM fatty acid. Three C(18) fatty acids, ole...
Anaerobic ammonium-oxidizing (anammox) bacteria have the unique ability to synthesize fatty acids containing linearly concatenated cyclobutane rings, termed "ladderane lipids." In this study we investigated the effect of temperature on the ladderane lipid composition and distribution in anammox enrichment cultures, marine particulate organic matter, and surface sediments. Under controlled labor...
detritylation of 5'-dimethoxytrityl nucleosides have been quantitatively achieved in minutes at room temperature under aprotic neutral conditions by using stannous chloride. of additional practical consideration and in contrast to protic acids, no depurination was observed with this reagent.
Interactions of two adamantyl molecules: 3-(adamantan-1-yl)propan-1-aminium chloride (compound A) and 1-hydroxyadamantan (compound B) with multilayer liposomes composed of L-α-phosphatidylcholine, cholesterol and dicetylphosphate, spin labelled with n-doxylstearic acids (n = 5, 7, 10, 12, 16) were investigated. In the presence of aminium salt (A) or alcohol (B) the increased dynamics of 5-doxyl...
