Essay about The Functions of Proteins

The human body is an incredible system that is capable of working a multitude of diverse functions. Without the help of the many different protein molecules, the human body would not be able to function properly. One major group of proteins called enzymes are mandatory for essential life. These proteins are constantly at work assembling molecules, metabolizing energy, and fighting off infections. An enzyme is a macromolecule that acts as a catalyst that speeds up a chemical reaction without being consumed by the reaction. Without these proteins, these reactions would take place too slowly to keep us alive. Essential parts in your body like vitamins and minerals cannot do any work without

Proteins are important for the human body. Proteins play many important roles in the body including the structure of enzymes; these are important proteins that help reactions occur in the body, such as releasing from the food we eat. Proteins also function as transport proteins such as hemoglobin; an iron

Proteins are important as they help build muscles and help the body repair itself. Without protein we would probably be very weak. One way proteins help our body helps our bodies is that enzymes act as catalyst for chemical reactions in our bodies. This helps the body perform more efficiently. Antibodies are also proteins. These proteins help the body defend against infection. Proteins also act transport. They help bind atoms and molecules and transmit them throughout cells and the body. Proteins provide many uses to our body and are therefore important. We need

DVL 1 protein is a cytoplasmic phosphoprotein produced by DVL 1 gene regulating the cell formations and a transducer particle for the developmental processes such as neuroblast specification and segmentation.1 In Wnt Signalling Pathway, the DVL 1 protein works by binding to C-terminus of frizzled receptors and transduce the wnt signal in both canonical and non-canonical pathway.2 These pathways activation lead to the accumulation of beta catenin protein in the cell which known to have important roles in proliferation and formation of the cells.2

Proteins in our diet are essential to our bodies for the promoting of lean tissue growth. The function of immunity in our body needs foods that are full of protein. Essential hormones and enzymes depend on proteins for their making. Growth in children and adults, tissue repair and immune functions are all depended on proteins in their work.

Proteins are one of the key biomolecules that make up the human body and facilitate different processes and reactions in the body (Silverthorn, 2016). Proteins exist in every cell in the human body and there are many different types of proteins with specialized functions that are necessary to maintain homeostasis (Silverthorn, 2016). Enzymes are a type of protein that performs like catalysts in the cells and start specific reactions (Ira, 2009).Catalysts start or increase the rate at

Proteins are one of the four main macromolecules in biology. Protein are made of amino acids, where there are a total of 20 distinct ones with different polarity. Proteins has a start, an N- terminus, and an end, C- terminus. The N- terminus is compose of amines (NH2) and the C- terminus is compose of the carboxyl group (-COOH). The building blocks are linked via a peptide bond, also known as amide bond, via condensation reaction. This macromolecule (proteins) has many function and “are responsible for nearly every task of cellular life, including cell shape and inner organization, product manufacture and waste cleanup, and routine maintenance” (http://www.nature.com/scitable/topicpage/protein-function-14123348).

Carbohydrates give the body energy. As the body's main source of fuel, carbohydrates are needed for physical activity and organ function. All the cells in the body need carbohydrates to function. Carbohydrates are also important for intestinal health and waste elimination. Proteins are extremely important in our cells. Proteins are involved in almost all cell function. Every protein in the body is designed for a specific task. Proteins are used in structural support, bodily movement, and in defense against germs. Proteins vary in structure and in function. They are constructed from a set of twenty different amino acids and each protein has a distinct three-dimensional shapes.

Enzymes are important to the human body because without it the reactions that do take place in the body would be to slow to keep a person alive. Some examples of enzymes are: pepsin, amylase, and lipase. Pepsin enzymes are found in the stomach they digest proteins. Amylase enzymes are found in the mouth it helps break down starch. Lipase enzymes break down fats. Also, Lipase enzymes help convert fat into energy.

Protein helps to maintain and replace the tissues in our bodies. Both children and adults need plenty of protein to grow and develop. The body uses protein as a secondary source for energy. It forms the structure of every cell, tissues, internal organs, tendons, skin, hair and nails. Meat, eggs and dairy products are considered complete proteins, but vegetables, beans and other plant products are considered incomplete proteins.

Proteins are essential for cellular functions in all forms of life. Though proteins have been studied for decades, membrane proteins have not been properly understood due in part to their physical complexity and the difficulties in testing. Though many challenges hinder the discoveries in this area of biochemistry, Professor Alessandro Senes believes that the difficulties encountered only make the results more worthwhile. Researching these proteins advances our understanding of the importance of the protein structure on the molecular function in the cells. As Professor Senes and his team continue to explore recurring patterns in these membrane proteins, they further explore new topics in this growing area of science.

Not only does hemoglobin has four heme groups, but it also has four polypeptides (two beta globin protein and two alpha globin). The two beta globin protein chains combines with two alpha globin protein chains and a heme which forms the predominant hemoglobin that is found in human adults.

Protein- Proteins are very large molecules that have hundreds of small units of amino acid these acids join together to make the walls of protein; these acids make up many forms of protein. Once the animal has digested something such as their meals the walls of protein will begin to break down and then the cycle of creating protein is repeated. This nutrient is vital in an animal's body as it has very important roles and responsibilities. The first of these functions repairing muscles and other body tissues forming new skin cells. which is needed for the animal to grow fur and for the body to develop. Protein regulates enzymes and other hormones and finally, plays a huge role in the production of energy in an animal.

Proteins : are organic nutrients that are chemically similar to fats ( lipids ) and carbohydrate since they contain carbon , hydrogen and oxygen atoms . Also proteins contain nitrogen , actually nitrogen is the cells that need to make a big group of important biological compounds. Animals , plants , bacteria and viruses contain large amount of proteins . Any cells in human body contain proteins . There are a lot of proteins in human body have a different function . So the body use proteins to : first , body use proteins to make, maintain and repair cells such as cells during period of growth they need protein to form cells membranes .second , to build structures such as keratin which is a structural protein it’s in hair,
