用傅里叶变换红外光谱技术研究了不同重复基序数目的小麦麦谷蛋白高分子量亚单位中心重复结构域(21、45、110和203个残基)的合成和重组多肽模型，以及一个相对分子质量为58,000 Da的重组多肽(1Dx5)。干肽的光谱非常相似；在低水分(
Synthetic and recombinant peptide models of the central repetitive domain of the high molecular weight subunits of wheat glutenin with different numbers of the consensus repeat motifs PGQGQQ + GYYPTSLQQ (21, 45, 110, and 203 residues long) and a recombinant 58,000-Da relative molecular mass (M-r 58,000) repetitive peptide from a single subunit (1Dx5) are studied using Fourier transform lR spectroscopy. The spectra of the dry peptides are very similar; at low water contents (
