What are the elements that make up the human body?

These compounds are composed of elements such as carbon, hydrogen, oxygen, nitrogen, and phosphorus. Any study done to determine nutritional status must take into account the state of the body before and after experiments, as well as the chemical composition of the whole diet and of all the materials excreted and eliminated from the body (including urine and feces).

How many amino acids are there in the human body?

About twenty amino acids are found in the human body, and about ten of these are essential. The synthesis of some amino acids can be limited under special pathophysiological conditions, such as prematurity in the infant or individuals in severe catabolic distress, and those are called conditionally essential.

Where do nutrients diffuse?

After large food molecules get digested by enzymes, the small soluble nutrients diffuse into the small intestine walls and then into the blood. Sometimes the concentration of nutrients i.e. glucose may be higher in the blood than in the small intestine. In such cases diffusion cannot be relied upon.

What is chemical digestion?

Chemical digestion involves breaking down large, insoluble food into smaller soluble nutrients that can be absorbed and used by the cells. Chemical digestion is carried out by enzymes. A lot about chemical digestion has already been covered above in regards to the alimentary canal, and what enzymes are found where.

What is the process of mechanical digestion?

Stomach. Mechanical digestion occurs as the stomach walls squeeze the food to liquefy it. Gastric juices contain pepsin (a protease) which chemically digests proteins. It also contains hydrochloric acid which kill bacteria, but also maintains an optimum acidic pH for pepsin.

What is the function of the pancreas?

The pancreas secretes pancreatic juice into the duodenum. The juice contains a large variety of different enzymes involved in the chemical digestion of food. Proteases break down proteins. Lipases break down lipids. Amylases break down carbohydrates. Most enzymes in the pancreatic juice have an optimum pH of around 7.

What is the pH of pancreatic juice?

Most enzymes in the pancreatic juice have an optimum pH of around 7. The pH of pancreatic juice is slightly alka line, and this is to neutralize the acidity of the food coming from the stomach.

What enzymes break down carbohydrates?

Lipases break down lipids. Amylases break down carbohydrates. Most enzymes in the pancreatic juice have an optimum pH of around 7. The pH of pancreatic juice is slightly alka line, and this is to neutralize the acidity of the food coming from the stomach.

Most vitamins come from fresh fruit and vegetables, with some also found in fish, meat, dairy, and eggs. Minerals, such as calcium and iron, also help the body perform optimally. The best sources are vegetables, dairy, meat, and some fish. Read more: Vitamins and Minerals.

How does the digestive system work?

Digestion is a vital process in humans, which provides energy by breaking down the large food molecules into easily absorbable molecules to produce energy for various life processes. The complete process of digestion happens through a stepwise process which is common to all living organisms. The complete process of digestion in Human digestive system is described below: 1 Ingestion: It is the process of us ingesting the food by eating it. In the mouth the food material is subject to cutting, tearing, chewing, and a little bit of digestion using the salivary juice and finally swallowing. 2 Digestion: It is the breakdown of the ingested food into microscopic and finally molecular fragments. Digestion occurs in the oral cavity, stomach and in the small intestine. 3 Absorption: This is a critical stage where nutrients are taken up from digestive organs and distributed to the body’s tissues. This process is where food ingested is converted to actual energy to be used by our bodies. 4 Excretion: This is the final process where waste material is excreted from our bodies.

What are the best sources of minerals?

Minerals, such as calcium and iron, also help the body perform optimally. The best sources are vegetables, dairy, meat, and some fish. Read more: Vitamins and Minerals.

What are the sources of energy for the body?

Dairy food, meat, seeds, and nuts all supply fats, as do vegetable oils. Fat is digested into fatty acids, which are used as an energy source and to make cell membranes. They may be rebuilt into fat, under the skin, which insulates the body and helps to keep us warm.

What are the sources of protein?

Rich sources of proteins are fish, meat, poultry, and beans. Once digested, proteins supply the body with amino acids. These building blocks are reassembled by cells into different proteins used for construction such as enzymes, and a myriad of other roles.

What percentage of the body is made up of water?

Water. Around 50 – 70 per cent of our body is made of water. Therefore this amount should always be maintained in the body. Water is the only medium through which all essential nutrients, vitamins, minerals and other wastes in the body are transported. Water also plays a vital role in regulating the body’s temperature.

What is the difference between monounsaturated and polyunsaturated fats?

Monounsaturated fats help regulate blood cholesterol levels, thereby reducing the risk for heart disease and stroke . A poly unsaturated fatty acid is a fatty acid with two or more double bonds or two or more points of unsaturation. Soybean oil contains high amounts of polyunsaturated fatty acids.

What is the cis configuration of fatty acids?

Naturally occurring fatty acids usually have a cis configuration. In a trans fatty acid, the hydrogen atoms are attached on opposite sides of the carbon chain. Unlike cis fatty acids, most trans fatty acids are not found naturally in foods, but are a result of a process called hydrogenation.

How do lipids work?

How Lipids Work. Lipids are unique organic compounds, each serving key roles and performing specific functions within the body.

What determines if a compound is solid or liquid?

Fatty acids determine if the compound is solid or liquid at room temperature. Fatty acids consist of a carboxylic acid (−COOH) group on one end of a carbon chain and a methyl group (−CH3) on the other end. Fatty acids can differ from one another in two important ways—carbon chain length and degree of saturation.

What is the methyl group of a fatty acid?

Fatty acids consist of a carboxylic acid (−COOH) group on one end of a carbon chain and a methyl group (−CH3) on the other end. Fatty acids can differ from one another in two important ways—carbon chain length and degree of saturation.

How many carbons are in a fatty acid?

Fatty acids have different chain lengths and different compositions. Foods have fatty acids with chain lengths between four and twenty-four carbon s and most of them contain an even number of carbon atoms. When the carbon chain length is shorter, the melting point of the fatty acid becomes lower—and the fatty acid becomes more liquid.
