Proteins can be described according to their large range of functions. The first function is antibodies. Proteins formed antibodies that help prevent infection or disease in the body. They often work in conjunction with the other immune system cells. For example, these antibodies identify and then surround antigens in order to keep them contained until they can be destroyed by white blood cells. The next function is enzymes. Enzymes carry almost thousands of chemical reactions that place in the cells. They assist with the formation of new molecules by reading the genetic information of the DNA. The third function is transport of molecules. This is a major element in the transport of specific molecules. For example, the haemoglobin is a protein

Fats fall into two categories: saturated and unsaturated. Unsaturated fats can be either monounsaturated or polyunsaturated. Unsaturated fats are better for you than their saturated counterparts, since consuming saturated fats raises the levels of cholesterol in the blood. Saturated fats do this two ways: They help create more cholesterol in the liver, and they suppress LDL receptors on liver cells, reducing the speed of removal of LDL from the blood. Saturated fats are primarily found in foods of animal origin such as butter, milk, egg yolks and meat. Saturated fats are solid at room temperature. Unsaturated fats, on the other hand , are liquids at room temperature. Foods that contain monounsaturated fats are polyunsaturated fats and may help to decrease your blood-cholesterol level if substituted for foods containing saturated fats.But fats are a necessary part of our diet .We need them to absorb vitamins A, D, E, and

Saturated fats are fats whose carbon-carbon bonds are single and each carbon atom has two or three hydrogen atoms; in other words, the carbons in fats of this type is “saturated” with hydrogen, hence the hydrophobic nature of fats and lipids in general. The single bonds between carbons makes

The sequence of amino acids determines each protein's unique 3-dimensional structure and its specific function. Antibodies bind to specific foreign particles, such as viruses and bacteria, to help protect the body. Enzymes carry out almost all of the thousands of chemical reactions that take place in cells. Proteins do most of the work in cells and are required for the structure of the cell, the function of the cell, and the regulation of the body’s tissues and organs in the cell. They are made of groups called amino acids.Proteins have a large variety of different shapes and sizes. If the shape changes, it becomes a new protein. Protein is found in your muscles and the cell

Proteins themselves are made of long chains consisting of a possible 20 different amino acids that are linked together by peptide bonds made up by the hundreds or thousands for each different protein. These different combinations of chains determine the specific protein’s function and 3-D structure. A large percentage of work that is put into every cell is the result of proteins, as well as many crucial factors of the body, such as functioning organs. Proteins are not sectioned to perform any certain one function, but instead are responsible in varying areas all throughout the body. Enzymes, antibodies, cell structure, along with a multitude of other tasks, are the product of the many types of proteins working in synergy. Proteins have 4

1. Janine and Mitchell were talking about carbohydrates and proteins. Proteins are large and complex molecules that play many roles in the body. Our body contains many cells that are responsible for a specific job. Proteins do most of the work in cells that are required for the structure, function, and regulation of the body 's tissues and organs. In each cell there is a lot of proteins that work together like a machine to run each cell, just like the engine in a car proteins look different and they all have different tasks that allow the engine to run. Proteins are made of amino acids that are attached to one another in a long chain. Proteins are needed for mechanical support(a fibrous protein), and also needed for immune

Proteins are the main manufacturing blocks and apparatuses for all living organisms. There are many types of proteins, which differ from cell to cell, in the human body. They build up the cellular and mediate biological/ metabolic processes. Proteins are key constituents of the human body, each cell of the body contains a number of proteins that play various biological processes such as structural, enzymatic and material transportation, those that are vital to life and through which the human body performs its functions properly.

Fibre is the indigestible portion of plant foods that helps move food through the digestive system. It softens stools by absorbing water. Fibres, also known as “bulk “or “roughages” can be found in whole

Fatty Acids have a linked chain of carbon atoms. These atoms can be unsaturated or saturated. Saturated means that there is only a single bond in carbon atoms, which leaves hydrogen to have the rest of them. Unsaturated means that there has to be at least once carbon atom that needs to have a double bond. In the case of Omega-3 Fatty Acids, Essential Fatty acids are polyunsaturated. Polyunsaturated fat is fat that has a lot of double bonds in between carbon atoms. They have to contain at least two double bonds. A double bond is when there are two atoms that share two electrons. “In all omega-3 fatty acids, the first double bond is located between the third and fourth carbon atom counting from the methyl end of the fatty acid (n-3)” (Higdon). There is a double bond that is the first on the carbon chain in between the third and forth chain. These double bonds are on a carbon chains which are in all omega-3 fatty acids. Another example of another fatty acid is omega-9. Omega-9 has its first double bond in between the ninth and tenth carbon atom. Omega-3 fatty acids are very good for a person to have.

Fatty acids are composed of a hydrophilic carboxylic acid group attached to a fatty hydrophobic chain of carbon atoms, referred to as the fatty tail. The fatty acids are classified as either saturated or unsaturated depending on the structure. Saturated fatty acids contain only single bonds with hydrogen atoms throughout the length of the carbon chain fatty tail and are therefore considered saturated with hydrogen. The regular structure of saturated fatty acid molecules makes it possible for them to stack close together causing them to easily form solids. Saturated fatty acids are solid at room temperature. Unsaturated fatty acids contain one or more double bonds to hydrogen in the carbon chain. The double bonds create a bend in the

Fats - Fats are made up of triglycerides and cholesterol. In each tissue in an animal, cholesterol can be found whereas, triglycerides have a glycerol backbone with the fatty acids attached. All of the different forms of fat are determined by the different combinations of fatty acids attached. As the word is known in most cases a lot of fat is not good however these fats can be synthesized in the body. However, there are vital fatty acids that are needed in an animal's body. Fats contain two and half times the amount of energy that protein and carbohydrates supply therefore is a major energy source for the animals. As well as that fat also carries the fat-soluble vitamins (A,D,E & K) and finally fats increase the dietary palatability.

Proteins fall into two groups which are globular and fibrous. Globular proteins are mostly enzymes which are high folded. Fibrous proteins however are typically structural (Chemguide.co.uk, 2015). Their role is to give cells and tissues structural integrity and strength (Crowe and Bradshaw, 2014).

Production of proteins is one of the most significant processes taking place in the cell. The role of proteins in a cell range from structural, enzymatic and hormonal functions. DNA is responsible for

Polyunsaturated fatty acids are also called omega 3 fatty acids. They have a double bond of carbon and carbon. The second carbon bond starts just at the edge of the first carbon bond. They are double-ended acids. The two ends are that of (COOH) and (CH3). These are the methyl end and the acid ending. The methyl ending is also referred to as the omega ending. The benefits of the polyunsaturated fatty acids have been controversial. In some medical acceptances and language, they are called essential fatty acids. The meaning behind this is that they cannot be synthesized by the body cells and metabolic activities. Nonetheless, they are very important for the body's metabolic activities. Typical mammals have no innate ability to synthesize fatty acids. Nonetheless, they have the ability to develop chains that lead to an interconnection between carbons in the body to form polyunsaturated fatty acids (Bracco 1992, p. 45).

Saturated fat can lead to increased cholesterol and subsequent heart disease, according to the American Heart Association. The largest source of saturated fat in my diet is likely generated by the beef from the occasional burger I consume.
