Proteins and Their Functions

Proteins are the basis of the protoplasm (fluid living content of the cell that contains the cytoplasm and cell nucleus) and are found in all living organisms. Proteins make up the bulk of animals body’s non-skeletal structure. As enzymes, they catalyze biochemical reactions; as antibodies, they prevent the effects of invading organisms; and as hormones, they control metabolic processes (C. Bissonnette, 2011). The Biuret test was used to detect the presence of peptide bonds within proteins, and they were found present in test tube #9 (control for peptide bonds).

Each gene acts as a code, or set of instructions, for making a particular protein. They tell the cell what to do, give its characteristics, and determine the way its body works. Each protein has a unique sequence of amino acids. This means that the number and order of amino acids is different for each type of protein. The proteins fold into different shapes. The different shapes and sequences give the proteins different functions, e.g. keratin are a fibrous protein found in hair and nails. If the gene has even the slightest of disorder within its sequence it could lead to an inaccurate order of amino acids

Protein: (formerly) a substance thought to be the essential nitrogenous component of all organic bodies

2. protein provide structure in every cell in our body- Proteins are present in all areas and processes of the cell. proteins hep maintain the cell keep its shape, and control the movement of particles in and out of the cell. It also help send signal and repair of damaged cells. Proteins control movement in the cell division.

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 polymeric chains that are built from monomers called amino acids. All structural and functional properties of proteins derive from the chemical properties of the polypeptide chain. There are four levels of protein structural organization: primary, secondary, tertiary, and quaternary. Primary structure is defined as the linear sequence of amino acids in a polypeptide chain. The secondary structure refers to certain regular geometric figures of the chain. Tertiary structure results from long-range contacts within the chain. The quaternary structure is the organization of protein subunits, or two or more independent polypeptide chains.

The Functions of Proteins Introduction Protein accounts for about three-fourths of the dry matter in human tissues other than fat and bone. It is a major structural component of hair, skin, nails, connective tissues, and body organs. It is required for practically every essential function in the body. Proteins are made from the following elements; carbon, hydrogen, oxygen, nitrogen and often sulphur and phosphorus.

The amount of protein taken differs by varies individuals. However, many protein misconceptions come from people close to us. According to Duellman, Lukaszuk, Prawitz, and Brandenburg (2008) coaches, parents, and friends in general, could mislead athletes. This fosters wrong ideas about the amount and benefits of protein conception which makes athletes believe that consuming a large amount of protein will aid with muscle gain and strength. When coaches guarantee better performance and higher muscle mass, athletes cannot but head towards the protein supplements. However, what coaches fail to acknowledge is that consuming a high dose of protein can be dangerous (Fox et al., 2011).

Proteins make up the building blocks of our entire bodies. It is the second most abundant substance

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 built inside of cells using DNA. DNA is located in the nucleus of ever eukaryotic cell and is stored in chromosomes. DNA starts out all messy like a bowl of spaghetti, but then begin to tighten up and form chromosomes.

Proteins serve a myriad of functions whether within or outside of the cells. These functions include structural roles (cytoskeleton), transport of

important role because every living organism needs proteins in order to speed up the biochemical

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

Protein is a very important macro nutrient, that is required for almost all biological processes in a living organism (Journel, Chaumontet, Darcel, Fromentin, & Tome, 2012).
