Thus‚ if we remove water from carbohydrates‚ all that remains is carbon. Carbohydrates can be divided into 3 categories; monosaccharides‚ disaccharides and polysaccharides (Table 1). Table 1.

stomach. Chemical digestion involves in a liquid that is acidic. The first part of chemical digestion is in the mouth‚ this liquid is called saliva. Saliva is a clear type liquid; this liquid is thicker than water. Saliva is produced in the mouth by salivary glands. Saliva has a medium pH level (6-7)‚ so it is slightly acidic so it does not digest the food into smaller atoms as much as the stomach. When the food goes down the oesophagus to the stomach‚ saliva is used as a lubricant to help the food slide

Digestion is a process in which the food that we eat is broken down into tiny nutrients to be taken in by the body. Within the human digestive system‚ chemical and physical reactions occur that allow for the digestion and the absorption of proteins into the bloodstream. The purpose of this paper is to show how chemistry relates to the daily functions within the body. There are two types of digestion processes‚ which are called mechanical and chemical digestion. Mechanical digestion includes the

The principal structure of the digestive system is an irregular tube‚ open at both ends‚ called the alimentary (al-i-MEN-tar-ee) canal or the gastrointestinal (GI) tract. In the adult‚ this hollow tube is about 9 meters (29 feet) long Think of the tube as a passageway that extends through the body like a hallway through a building. Food must be broken down or digested and then absorbed through the walls of the digestive tube before it can actually enter the body and be used by cells The teeth

If I told you that you were‚ on a daily basis‚ consuming food that could potentially give you serious health issues‚ would you still eat it? The human body is in fact‚ designed to sustain a vegetarian diet. Most of you are‚ on a daily basis eating meat‚ poultry or fish – which have also been linked to a large number of chronic diseases and cancers. Alongside this‚ animals are treated extraordinarily cruelly and inhumanely when it comes to satisfying us humans. This is wrong and needs to be fixed

intestine—also called the colon—rectum‚ and anus” (NDDIC). Digestion begins in the mouth‚ where the food is cut and ground into small pieces. As the food is broken up‚ the first phase of chemical digestion occurs as saliva‚ which is secreted from the salivary glands. Amylase‚ contained in the saliva‚ begins the breakdown of starches into sugar. Once the food is softened by the saliva and swallowed into the esophagus‚ a muscular action‚ called peristalsis‚ helps to then push the food down the esophagus and into
