Food: The Essentials And Characteristics Of Food

Food are consists by essential of fats, protein and carbohydrates. This all elements are needed in the body of an organism because to sustain growth, repair cells and give energy. From the above pictures show the food packaging of the Instant Asam Fish Sauce by the Mak Nyonya brand. This food is mostly consume by the students because it cheap, easy to cook and have all nutrients that body need. From the packaging, it states that the food have 12.6g of the saturated fats, 2.8mg of the sodium, 22.5g of carbohydrates, 7.4g of dietary fibre, 2.2g of sugar, 4.8g of protein, 16.6g of calcium and 2.5g of iron. From the natural facts, the food is very suitable for consume. Food usually consists higher amount of protein. Protein can be found in

These because the protein is function as maintenance, development and repair of body tissue. Other than that, almost all the part of the body like eyes, skin and hair are made from protein. Usually, the children are need more amount of protein per kilogram of body weight than the adults. These because the protein is helped for developing their new protein tissue and for growing. Other than that, protein also important because it is the major sources of energy. According to Ellen (n.d), if a person consume more amount of protein than their need for maintenance of body tissue, the body will use the protein as energy although the main function of protein as maintenance of body tissue and for growth. As result, the person does not need to take another energy sources such as carbohydrate because the protein will be use to become parts of fat cell. Next, protein also can take part in creation of hormones. These protein are importance to help control body function such as insulin. Insulin is small protein and act as hormones for regulate blood sugar for human. The necessary amount of insulin is important to ensure the person is healthy and avoid the person from get diabetes. Next the other example of protein hormones is secretin. Secretin is important in digestive proteins when it stimulating the pancreas and intestine to create the digestive

The primary structure is made by the process of protein biosynthesis. In addition, primary structure determined by the gene corresponding to the protein. The sequence of the amino acid can be determined by Edman Degradation, tandem mass spectrometry or by the sequence of gene using genetic code. For the secondary structure is by actual polypeptide backbone chain. According to Linus (1951), there are two types of secondary structure which are alpha helix and beta sheets. The secondary structure can be refer by the patterns of hydrogen bonds and for secondary structure, they do not form any regular structure. Tertiary structure can be defined by three dimensional structure of protein molecules. The alpha helix and beta sheet will folded into globular structure cause by hydrophobic interaction. For the quaternary structure is refers to three dimensional structure of multi subunit protein and it stabilized by the same of non-covalent interaction and the disulfide
