The strong α‐doublet running behind the fastest major α‐gliadin of Cappelle‐Desprez on gel electrophoresis has been separated into three proteins. They were named: slow, middle and fast (S, M and F) from their mobilities on alkaline gels. The amino acid compositions were typical of gliadins, with no free thiol groups. Molecular weights and % amidation were: S31000, 96; M32 000, 94; F29000, 91. No convincing evidence for a glycoprotein nature was found. At acid pH the order seems to be, in decreasing mobility, F, S, M.
