Riassunto

È stato studiato l'assorbimento della glucosamina e della N-acetilglucosamina utilizzando segmenti intestinali tagliati trasversalmente (strips) e sacchetti di intestino tenue di ratto. Il flusso di trasporto della glucosamina nelle cellule intestinali è mediato da carrier, indipendente dallo Na+ e procede senza accumulo attivo. La N-acetilglucosamina sembra, invece, essere assorbita per mezzo di un semplice processo di diffusione.

L'assorbimento, sia della glucosamina che della N-acetilglucosamina non comporta modificazione della loro struttura molecolare.
