1 Individual differences in AMY1 gene copy number, salivary alpha-amylase levels, and the perception of oral starch. Starch amylase alpha 1A Homo sapiens
2 BACKGROUND: The digestion of dietary starch in humans is initiated by salivary alpha-amylase, an endo-enzyme that hydrolyzes starch into maltose, maltotriose and larger oligosaccharides. Starch amylase alpha 1A Homo sapiens
3 BACKGROUND: The digestion of dietary starch in humans is initiated by salivary alpha-amylase, an endo-enzyme that hydrolyzes starch into maltose, maltotriose and larger oligosaccharides. Starch amylase alpha 1A Homo sapiens
4 Finally, we demonstrate that AMY1 CNVs predict an individual"s amount and activity of salivary amylase and thereby, ultimately determine their perceived rate of oral starch viscosity thinning. Starch amylase alpha 1A Homo sapiens
5 CONCLUSIONS: By linking genetic variation and its consequent salivary enzymatic differences to the perceptual sequellae of these variations, we show that AMY1 copy number relates to salivary amylase concentration and enzymatic activity level, which, in turn, account for individual variation in the oral perception of starch viscosity. Starch amylase alpha 1A Homo sapiens
