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.
Therefore, baking powder on its own is used in baked goods that do not already contain an acid. It works in the same way baking soda does, by creating air bubbles which cause the batter to rise. If you find yourself without baking soda you can always substitute baking powder for baking soda.
