Решение. №6 (с. 349)
Решение 2. №6 (с. 349)
Дано:
Трисахарид, образованный тремя мономерами гексозы.
Молекулярная формула гексозы: $C_6H_{12}O_6$.
Найти:
Общую молекулярную формулу трисахарида.
Решение
Трисахариды являются олигосахаридами, молекулы которых состоят из трех остатков моносахаридов, соединенных гликозидными связями. В условии задачи указано, что трисахарид образован гексозами.
1. Молекулярная формула гексозы (моносахарида с шестью атомами углерода, например, глюкозы или фруктозы) — $C_6H_{12}O_6$.
2. Для образования трисахарида три молекулы гексозы должны соединиться друг с другом. Соединение происходит за счет реакции конденсации (дегидратации), при которой из гидроксильных групп двух соседних моносахаридов образуется гликозидная связь и отщепляется одна молекула воды ($H_2O$).
3. Чтобы соединить три молекулы в линейную или разветвленную цепь, необходимо образовать две гликозидные связи. Например, первая молекула соединяется со второй, а вторая — с третьей. Следовательно, при образовании трисахарида из трех молекул гексоз выделяется две молекулы воды.
4. Рассчитаем итоговую формулу. Сначала суммируем атомы трех отдельных молекул гексоз:
$3 \times C_6H_{12}O_6 = C_{18}H_{36}O_{18}$
5. Затем из полученной суммы вычитаем атомы двух молекул воды ($2H_2O$), которые были отщеплены при образовании двух гликозидных связей:
Итоговая формула = $(C_{18}H_{36}O_{18}) - (2H_2O) = C_{18}H_{(36 - 2 \cdot 2)}O_{(18 - 2 \cdot 1)} = C_{18}H_{32}O_{16}$
Таким образом, общая молекулярная формула для трисахаридов, образованных гексозами, — $C_{18}H_{32}O_{16}$. Примером такого вещества является рафиноза, состоящая из остатков галактозы, глюкозы и фруктозы.
Ответ: $C_{18}H_{32}O_{16}$.
