Webphosphoamide bond is highly unstable to acid, we digested [32P]phosphoryl-peptide with alkali to obtain [32P]phospho-amino acid. The [32P]phosphoryl-peptide was hydrolyzed with 3 N KOHat 100°C for various times, and the hydrolysates were electrophoresed on DEAE-cellulose paper. As shown in Figure 4A, three radioactive spots were observed at an ... Phosphoramide is a chemical compound with the molecular formula O=P(NH2)3. It is a derivative of phosphoric acid in which each of the hydroxyl groups have been replaced with an amino group. Phosphoramide arises from the reaction of phosphoryl chloride with ammonia. It is a white solid that is soluble in polar … See more Phosphoramide is also the parent compound for a range of derivatives called phosphoramides.
