Two enzymes, lactase-phlorizin hydrolase (LPH) and sucrase isomaltase (SI), are anchored to the mucosal surface of the small intestine where the soluble sugars in the lumen are hydrolyzed to free glucose, galactose, and fructose, which are absorbed rapidly from the lumen.
How to substitute baking soda for baking powder. You can substitute baking soda for baking powder, if you increase the amount of acidic ingredients in the recipe to offset the baking soda. Youâll also need much less baking soda as it is 3 times as powerful as baking powder. Youâll need about a teaspoon of vinegar or lemon juice for every 1/2 teaspoon of baking soda.
Yes, Baking Powder has a acidic powder mixed with it to create air bubbles, a rising action. Baking Soda does not have this. You could sub if you had some creme of tarter to initiate the soda/acid reaction. Or (depending on the cake recipe) some sour cream, lemon juice, or buttermilk. Still it would be a guess.
