Vitamin B12 Absorbsion Ve Malabsorbsionu

Abstract

Proteine bağlı olarak besinlerlerle alınan vitamin B12, mide ve ince barsağın üst kısmında proteinden ayrılır ve GIF ile bira leşir. Oluşan GIF-vitamin B12 kompleksi enzimler, bakteriler ve diğer faktörlerden etkilenmeden ileumun son kısmına ulaşır. Fırçamsı kenarda özel reseptörlere yapışır. Epitel hücresinde GIF'den ayrılan ve daha çok mitokondride toplanan vitamin B12, spesifik bağlayıcılar olan transkobalaminler tarafından portal yol ile depolara taşınır. Vitamin B12 malabsorbsiyonu en sık GIF yokluğu ve GIF'e karşı antikor varlığı ile karakterli pernisiyöz anemide görülür. Gastrektomi, ileumun distalini tutan ince barsak hastalıkları, kör halka sendromu, kronik pankreatitis, Dyphyllobotrium Latum infestasyonu ve diğer bazı hastalıklarda vitamin B12 ab* sorbsiyonu bozulur.
