Sucrase is an enzyme that plays a crucial role in the digestion of carbohydrates. It specifically breaks down sucrose, a common sugar found in many foods, into its simpler components: glucose and fructose. This process occurs primarily in the small intestine, where sucrase helps the body absorb these sugars for energy. The activity of sucrase is essential for individuals who consume foods containing sucrose, such as fruits, table sugar, and many processed products. A deficiency in sucrase can lead to digestive issues, as the body struggles to process sucrose effectively, resulting in discomfort and malabsorption of nutrients.
