Углеводы

Углеводы (сахара) — группа природных полигидроксиальдегидов и полигидроксикетонов с общей формулой (CH2O)n. Группа включает простые сахара (моносахариды) и их высокомолекулярные аналоги, олигосахариды ...

 
А. Биологические функции углеводов

Полисахариды, прежде всего крахмал и некоторые дисахариды, являются важными (хотя и не жизненно необходимыми) компонентами питания (см. Питание. Органические вещества). В кишечнике они расщепляются до моносахаридов, которые затем всасываются ...

А. Биологические функции углеводов
Б. Структура моносахаридов

Важнейший природный моносахарид, D-глюкоза, является алифатическим альдегидом, содержащим шесть углеродных атомов, пять из которых имеют гидроксильные группы (1). Поскольку атомы C-2 —C-5 являются хиральными центрами (см ...
