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.
If you have a baking recipe that calls for baking soda, and you only have baking powder, you may be able to substitute, but you will need 2 or 3 times as much baking powder for the same amount of baking soda to get the same amount of leavening power, and you may end up with something thatâs a little bitter tasting, depending on the recipe.
