摘要: Figure S1. ESI (+)-MS of mixtures containing reference saccharides in potassium phosphate buffer, without or with α-glucosidase. A) blank, buffer containing α-glucosidase only, B) blank, containing lactose in buffer only, C) lactose in buffer, with αglucosidase, D) blank, containing maltose in buffer only, E) maltose in buffer, with α-glucosidase, F) blank, containing maltotriose in buffer only, G) maltotriose in buffer, with α-glucosidase. Ions of saccharides are indicated by asterisks:*≡ Hex,**≡ Hex2,***≡ Hex3.
