Peptidomics of casein digestion in the pig duodenum

Data accompanied with the paper "Digestion of micellar casein in duodenum cannulated pigs. Correlation between in vitro simulated gastric digestion and in vivo data" Food Chemistry vol. 343, 128424 (2021). The data are generated through the analysis of the duodenal content of six pigs fed milk casein. Samples after 5, 10, 15, 20, 30, 45, 60, 120 and 150 min of intake were analyzed by liquid chromatography coupled to tandem mass spectrometry after normalization of the protein content. A list of peptide sequences derived from milk caseins with indication of parent protein, subject number, time of digestion, position range in the mature protein and sequence in one-letter code is provided.本数据集配套发表于论文《十二指肠插管猪的胶束酪蛋白消化：体外模拟胃消化与体内数据的相关性》（"Digestion of micellar casein in duodenum cannulated pigs. Correlation between in vitro simulated gastric digestion and in vivo data"），刊载于《食品化学（Food Chemistry）》第343卷，文章编号为128424（2021年）。该数据集通过分析6头饲喂牛乳酪蛋白的十二指肠插管猪的十二指肠内容物生成。在受试猪摄入酪蛋白后5、10、15、20、30、45、60、120及150分钟采集的样本，经蛋白质含量归一化处理后，采用液相色谱-串联质谱法进行分析。本数据集提供了源自牛乳酪蛋白的肽序列列表，其中标注了肽段的母体蛋白、受试猪编号、消化时间、其在成熟蛋白中的位置区间以及单字母代码形式的序列。
