Lactose which is also known as milk sugar: β-D-Gal(1à4)β-D-Glc, where Gal is galactose and Glc is glucose.  Sucrose which is also known as table sugar: a-D-Glc (1-->2) b-D-Fru where Glc is glucose and Fru is fructose.

Name the three digestible disaccharides we talked about. What monosaccharides are they each made of and tell whether they are connected by an alpha 1-4 glycosidic linkage, a 1-4 beta glycosidic linkage or a 1-5 beta glycosidic linkage.

Raffinose (see prev. question for structure) is not digestible by humans yet is found in foods we eat all the time like beans, cabbage, brussels sprouts etc. What 2 human digestible compounds can Raffinose be broken down into? Just as a side note, Raff is NOT digestible by us, but our helpful gut bacteria break it down for us into the 2 compounds that are the answer to this question. O a-D-glucose O B-D-fructose sucrose a-D-galactose Lactose maltose
