Importance of Protein the Human Body
Huge biological molecules, proteins are basically one or multiple chains of amino acids that have a wide range of functions to perform in the human body. Its role in living beings include functions such as replicating the DNA, catalysis of metabolic reaction, stimuli response as well as transportation of the molecules to the destined location from the base location. The difference in the type of protein molecules is based on the sequence maintained by the amino acids, namely nucleotide sequence. It is this sequence of amino acids, which enables the protein chains to fold into a structure that are three dimensional, which is again responsible for determining the activity of the particular protein.

Role of Protein
Very much like the other biological molecules, protein forms an essential part of all living organisms as they have an active participation in almost every process that goes on within a cell. Certain proteins are in the form of enzymes such that they catalyze reactions , which are biochemical and are necessary for the process of metabolism. Protein also performs structural functions in the body. For instance, myosin as well as actin are muscle-specific proteins, which perform scaffolding that in turn is responsible for the maintenance of the shape of the cells.
Unlike microorganisms and plants that are known for biosynthesizing all the twenty standard amino acids, humans as well as animals require diet-based amino acids. Protein obtained from food is broken down through digestion into amino acids and absorbed by the cells. The process by means of which this process occurs is known as proteases, this involves exposure of protein to acids as well as hydrolysis so as to denature it. While some of the proteins are used up as a part of biosynthesis, others are transformed into glucose by means of gluconeogenesis. Protein acts as a fuel during the process of starvation as it is being stored in the muscles helps to support life.
Source of Protein
Proteins have the capacity to help one shed off the extra fat in the body. However, the health benefits can be obtained only when the right supplement of protein is taken in the right amount. Seafood forms the best source of protein since they are low in fat. Although certain sea fishes like salmon contains fat, it is healthy for the heart as fats like omega-3 is known for reversing heat diseases. White poultry meat is an excellent source of lean protein. Dairy products like milk, yogurt, and cheese are not only rich in protein but also in vitamin D and calcium. Skimmed dairy products increase the strength of bones and teeth. An egg a day is the safest means to attain protein, specifically the egg white. Beans are not only good source of proteins, but contains a great amount of fibers as well. Soy apart from being an important source of protein, is also admired as very heart healthy. This also helps in lowering cholesterol. Cereal or energy bar can suffice the body’s protein requirements in case there are instance of skipping meals. Only ensure that it contains not less than 6 grams of proteins and low fat and carbohydrate content. Check our website protein-direct.com for more such details.
