Энтальпия и энтропия

Изменение свободной энергии (ΔG) химической реакции зависит от ряда факторов, в том числе от температуры и концентрации реагентов (см. Равновесие). В этом разделе обсуждаются ещё два параметра, которые связаны ...

 
А. Теплота реакции и калориметрия

Все химические реакции сопровождаются выделением или поглощением тепла. Реакции первого типа называются экзотермическими, реакции второго типа — эндотермическими. Мерой теплоты реакции служит изменение ...

Б. Энтальпия и энтропия

Теплота реакции ΔH и изменение свободной энергии ΔG не всегда имеют сравнимые значения. В действительности известны реакции, протекающие спонтанно (ΔG меньше 0) несмотря на то, что являются эндотермическими ...

NMR Studies of Structural Motifs: Protein Folding and Ligand Binding / NMR of Structural Motifs: The agrin G3 domain is critical in development and maintenance of the neuromuscular junction. G3 binds -dystroglycan and initiates acetylcholine receptor clustering on myotube membranes. Using NMR spectroscopy, we show both active B8 and inactive B0 isoforms binding sialic NMR Studies of Structural Motifs: Protein Folding and Ligand Binding
