Main 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

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

3. Protein transport materials- Protein helps transport materials in the body. protein help in the movement of ions, and small molecules as across other

a. Proteins- macromolecules made of amino acids. Proteins have many functions in the body. Some sources of proteins are whole-grain cereals, dark breads,rice, beans, and meat.

My daily diet should contain a balance of proteins, carbohydrates (carbs), and lipids (collectively called macronutrients). According to Kirby (2011), micronutrients are substances such as vitamins, and minerals that are essential for healthy growth and developments. The body only requires small quantities of micronutrients and without them serious problems can arise. The role of each micronutrient makes proteins, carbohydrates, and lipids equally important in my diet. Proteins are important for repair and tissue growth, helps the body to make enzymes and hormones, as well as preserve lean muscle mass and is a source of energy. Carbohydrates are the body main source of energy and are easily broken down into glucose

Proteins are the metabolic workhorses of the cell; they engage in a variety of essential activities ranging from enzymatically catabolizing macromolecular food sources to serving as structural components that maintain cell stability. Maximizing protein function relies on intricate non-covalent interactions occurring on the secondary, tertiary, and quaternary levels that help determine the overall shape of the protein. In their native states, proteins will assume the most energetically favorable configuration. Occasionally however, cells are exposed to exogenous disruptions such as heat stress. Heat Stress can compromise protein three-dimensional structure. Hydrophobic residues tend to be buried in the interior of the protein but when

A protein has multiple existing structures, these are the primary, secondary, tertiary and quaternary structures which occur progressively. A protein is essentially a sequence of amino acids which are bonded adjacently, and interact with one another in various ways depending on the R group that the amino acid contains. There are 20 different amino acids which are able to be arranged in any given order, thus giving rise to a potential 2.433x1018 (4.s.f) different combinations, and therefore interactions between the various amino acids.

Proteins are complex structures made up of chains of amino acids. Each protein has a different function such as enzymes to catalyze reactions or protein hormones to trigger certain functions of a cell. First let’s start with the most basic component of a protein: an amino acid. An amino acid is made up of a central carbon atom attached to a hydrogen atom, a carboxyl group, an amino group, and an R group which varies

Amino Acids are essential nutrients that are the primary building blocks of proteins found in meat, dairy products, and legumes. Proteins make up 20 percent of the human body, and the amino acids that make up these proteins play a critical

There are many types of foods, nutrients, and minerals that are important to the body, and the ones that will be covered in this paper are electrolytes, carbohydrates, and proteins. The items listed above are vital to body functions in many ways; for example, electrolytes necessary for proper muscle contraction (Nordqvist 2013). Proteins are essentially what allow our bodies to function as they do, and carbohydrates provide us with the energy that allows it to function. Our body is an amazing and intricate machine, and that’s basically what it is -- a well-oiled machine. In this adventure we will discover what makes our bodies work the way they do, what moves the figurative cogs of our body, and what makes us tick inside.

Protein is made up of amino acids. Amino acids are the building blocks of your muscles and

Proteins are biological macromolecules made from smaller building units called amino acids. There are 20 natural occurring amino acids which can combine in various ways to form a polypeptide. There are four distinctive levels of protein structure: primary, secondary, tertiary and quaternary. The primary structure of a protein is important in determining the final three dimensional structure and hence the role and function of a particular protein, both in the human body and in life around us. The secondary structure of a protein can fall into two major categories; α-helices or β-sheets, other variants also exist such as β-turns {{20 Brändén, Carl-Ivar, 1934- 1991}}. The precise folding or these secondary structures into a three dimensional shape is known as the tertiary structure of a protein and multiple polypeptides bound together via covalent and non-covalent bonds forms the complex quaternary structure of a protein.

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.

Carbohydrate is a nutrient essential for energy production and the prevention of ketosis, a state where the production of ketones exceeds metabolism. Protein is a nutrient essential for its components, amino acids. Fat is a nutrient which provides insulation, protection and energy for the body.

Proteins cannot be stored except in eggs and seeds and they form the body's main structural elements and are found in every cell and tissue. The human body uses proteins for growth and to build and repair bones, muscles, tissue, skin, internal organs and blood. Hormones, antibodies
