PTERIN SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
pterin
Pterin, sırasıyla 4 ve 2 konumlarında bir keto grubu ve bir amino grubu olan bir pteridin halka sisteminden oluşan heterosiklik bir bileşiktir. Pterin'in birkaç totomeri var ve bunlar aşağıda gösterilmiştir. Pterin türevleri pterinler ve folatları içerir. Pterinler, bir grup olarak, başta tarif edilen temel pterin yapısının türevleri olan ve pirazin alt halkasına ek fonksiyonel gruplar eklenmiş bileşiklerdir. Pterinler ilk olarak kelebek kanatlarının pigmentlerinde keşfedildi (bu nedenle kanatlı Yunan pteronu (πτερόν) 'dan isimlerinin kökeni) ve biyolojik dünyada renklendirmeyle birçok rol oynuyor. Pterinler enzim katalizinde kofaktörler olarak da işlev görürler. Folatlar, pteridin halka sisteminin 6 pozisyonundaki metil grubuna bağlı p-aminobenzoik asit ve L-glutamat içeren "konjuge" pterinlerdir. Bunlar çok sayıda biyolojik grup transfer reaksiyonunda kritik bileşiklerdir.
