hydrogen bonds between Si−O−Si of attapulgite and N-H of humic/fulvic-like acids58, which may be conducive to the slow-release of slow-release nano fulvic-like acid fertilizer. In addition, no obvious new peak appeared in the spectrum of slow-release nano fulvic-like acid fertilizer ...
When hydrogen atoms interact with each other, they form a diatomic molecule called hydrogen gas. What type of bond holds two hydrogen atoms together in hydrogen gas? Which molecule can form hydrogen bonds with water but not with another molecule of itself? And why? (Hint: draw out the Lewis...
Chemical properties of 1,3-Diaminopropane[1] 1,3-Diaminopropane is a polar compound that can form hydrogen bonds. There are unshared electron pairs. Since this unshared electron pair is nucleophilic, its chemical properties are relatively active and it is easy to react with some electrophilic com...
Compound 19d does not form a network of hydrogen bonds with the side chains of Tyr473, His449, Ser289 and His323 in the polar cavity of the PPARγ as rosiglitazone does, but showed H-bond interactions with Cys285, Ser289, Tyr327 and Ser342. The absence of strong interactions may ...
Adenine and Thymine also have a favorable configuration for their bonds. They both have to -OH/-NH groups which can form hydrogen bridges. When one pairs Adenine with Cytosine, the various groups are in each others way. For them to bond with each other would be chemically unfavorable.Why...
Residues establishing direct hydrogen bonds as well as those with the most extensive hydrophobic contacts were mutated to alanine and the resulting variants were tested against CohScaE (Table S1). Alanine was chosen (unless otherwise stated below) because it typically represents a deletion of the ...

Intermolecular hydrogen bonds are mainly formed between the carbonyl and the amide group of SM and the 3-hydroxyl group and the phosphoryl oxygens (47). In comparison with SM, yeast IPC contains additional hydroxyl groups at the 2 position of the amide-linked fatty acid moiety (α-...
