पाचन केवल छोटे कणों में खाद्य कणों को तोड़ सकता है। एंजाइमेटिक हाइड्रोलिसिस नामक एक रासायनिक पाचन प्रक्रिया भोजन के भीतर आणविक 'बिल्डिंग ब्लॉक' वाले बंधनों को तोड़ सकती है। उदाहरण के लिए, प्रोटीन को उनके 'बिल्डिंग ब्लॉक' एमिनो एसिड में तोड़ दिया जाता है।

Digestion can break food particles in small particles only. A chemical digestive process called enzymatic hydrolysis can break the bonds of molecular 'building block' within the food. For example, proteins are broken into their 'building block' amino acids.

Digestion of food involves both physical and chemical processes. Through digestion, large food particles are converted into smaller components that can be readily absorbed into the bloodstream.


Action of sucrase on sucrose

Sucrose binds to the active site on sucrase, and this puts stress on the bond between the 2 sugars that make up sucrose. The bond breaks, releasing glucose and fructose.

Mechanical digestion

Food is taken into the mouth where it is broken down into smaller pieces by the teeth. As the teeth grip, cut and chew the food, saliva is released and mixes with the smaller food particles. Saliva moistens and lubricates the food, allowing it to be worked into a small ball called a bolus, which can then be easily swallowed.

This mechanical work on the food not only greatly increases its surface area but also allows it to be mixed with a digestive enzyme present in saliva.

Chemical digestion

Mechanical digestion can only break up the food particles into smaller pieces. A chemical digestion process called enzymatic hydrolysis can break the bonds holding the molecular ‘building blocks’ within the food together. For example, proteins are broken down into their ‘building block’ amino acids. Once released, these small molecules can then be absorbed through the gut wall and into the bloodstream.

An enzyme is a protein that can control the rate of biochemical reactions. In enzymatic hydrolysis reactions, an enzyme incorporates a water molecule across the bond, allowing it to break.
