Protein can be hydrolyzed, producing small chains of amino acids called peptides. Several studies have shown that protein hydrolysates containing mostly di- and tripeptides are absorbed more rapidly than free form amino acids and much more rapidly than intact proteins. In addition, there is recent evidence that protein hydrolysate ingestion has strong insulinotropic effect. Thus, recovery sports drinks containing protein hydrolysates may be of great value. Key PointsProtein hydrolysates containing mostly di- and tripeptides are absorbed more rapidly than free form amino acids and much more rapidly than intact proteins.Oral intake of protein hydrolysates and amino acids in combination with carbohydrates can result in an insulinotropic effect as much as 100% greater than with the intake of carbohydrates only.Recovery sports drinks containing protein hydrolysates and insulinotropic amino acids may be of great value, but more research is needed before firm conclusions can be drawn.
蛋白质可以被水解，产生称为肽的短链氨基酸。多项研究表明，主要含二肽和三肽的蛋白质水解产物比游离形式的氨基酸吸收更快，比完整蛋白质吸收快得多。此外，最近有证据表明摄入蛋白质水解产物具有很强的促胰岛素分泌作用。因此，含有蛋白质水解产物的运动恢复饮料可能具有很大价值。要点主要含二肽和三肽的蛋白质水解产物比游离形式的氨基酸吸收更快，比完整蛋白质吸收快得多。口服蛋白质水解产物和氨基酸与碳水化合物相结合，其促胰岛素分泌作用比仅摄入碳水化合物时可高出多达100%。含有蛋白质水解产物和促胰岛素分泌氨基酸的运动恢复饮料可能具有很大价值，但在得出确切结论之前还需要更多研究。
