Proteins have an important role in the body and must be ingested on a regular basis. They provide the body with the capacity to repair skeletal muscle tissue and to synthesize hormones and enzymes among other activities. In this experiment, we wanted to determine the organic molecules found in each brand of protein supplements and the amount of starch present. A protein supplement should contain amino acids and proteins; however, some supplements contain other molecules that are used as fillers
Protein denaturation is defined as the destruction of its spatial structures while retaining the primary structure. Globular proteins, such as egg white and soybean protein, are able to form gels upon heating (Doi, 1993). For a coagulum to form it is important that the functional groups (e.g. hydrophobic groups) within the protein are exposed. This makes it easier for the groups to interact and form a three dimensional network. Coagulum formation is complicated, and affected by the concentration
Protein-protein interaction refers to the physical contact between two or more proteins that result in a biological function. These interaction often take the form of molecular machines that carry out a diverse number of essential physiochemical processes. Specific interactions between the proteins of host and pathogen forms the primary basis of infection. The proteins involved in such interactions are referred to as ‘host-pathogen interactomes’. 1.2.2 Significance of PPI: Surface proteins of both
Proteins are important nutrients that contain the essential and non-essential amino acids which provide the body with energy. They control many metabolic functions in the body and are essential components of all living cells. Proteins are the basic building blocks of matter responsible for muscle growth and development, bones, ligaments and tissue. They also help to fight infections because they strengthen the immune system and are essential for maintaining body functions such as digestion, metabolism
Modern biotechnology focuses much on proteins. Protein engineering is dedicated towards the generation of novel molecules, intended as both proteins endowed with new functions by mutagenesis and completely novel molecules. After the revolution introduced in protein science by the advent of genetic engineering, protein engineering can be considered as the second wave of innovation which is providing important breakthroughs in basic research and application, useful for studies on structure-function
Protein aggregation: Toxicity and function, two sides of the same coin Protein misfolding and aggregation is linked to the onset of more than 40 human diseases. Although protein aggregation is potentially harmful for the cell and usually compromises its fitness, the vast majority of proteins contain sequences that predispose them to aggregate. The reason behind this apparent contradiction is that the presence of these sequence stretches provides a number of structural and functional advantages,
Protein is the most important macronutrient in the body. It is a necessary component of the human diet and used in almost every biological process in the human body. Protein rich source of foods are chicken, beef, eggs, milk, fish and of course sports supplements known as protein powders. Proteins can also be found in potatoes, rice, pasta, and nuts, however the majority of proteins found in these sources are not considered to be “essential” proteins. There are many different proteins to choose
that contains carbohydrates are grain products such as breads, cereals, pasta, and rice as well as fruits and vegetables. 2. Protein Protein are things from from food which is broken down into amino acids when they go to the digestive system. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues
The word 'protein' was oined by Jon's Jacob Berzelius in 1838. For the previous 150 years, however there had been the concept of an ' animal substance' slight variants of which were thought to make up muscles, skin and blood. Proteins are essential for the human body. There is no life without protein. The efficiency or degree to which dietary proteins can be used for building parts of the human body is determined principally by the type and relative amounts of the Amino acid present in the particular

Determination of protein content in feta cheese, there are three steps which are digestion, neutralization and titration. More than 90 % of protein containing samples and over 60 % of all other nitrogen
Protein folding in the cell is crucial for their function and existence of life. The ability of macro-molecules to assemble to three dimensional fold either with or without the assistance of cellular component has characteristic importance for a living system. It is important to understand the basis of folding mechanisms of proteins. Resolving protein folding mechanism and how folding processes are regulated is a challenging in the modern science. Protein needs to fold to their native or functional
Whey protein Whey protein is basically the protein contained in whey, the watery portion of milk generated as a result of producing cheese. Once considered a waste by-product, dairy companies now understand and recognize its benefits, resulting into its concentration and purification. Being an abundant source of branched-chain amino acids (BCAAs), it is used to stimulate protein synthesis. It includes these three amino acids: leucine, isoleucine, and valine. These three have been proven to be

To gain muscle, your body has to have enough protein to accommodate your new muscle tissue. Many bodybuilders do not
extent of such reactions should be specifically quantified in future studies as a means of accurately determining consequences of protein hydrolysis, (John O' Brien, et al.,1997). The quality and shelf life of fluid milk products are dependent on the amount and type of microorganisms present following pasteurization. This study evaluated the effects of different pasteurization processes on the microbial populations in fluid milk. The objective was to determine whether certain pasterurization processes
Protein synthesis Introduction Translation or protein synthesis is a central process of central dogma of molecular biology. It deals with production of proteins or chains of amino acids by making use of a mRNA as a template, ribosomes as protein synthesizing machinery and tRNA’s as carriers of amino acids during the translation process Living cells devote about 90 % of their chemical energy to synthesis of proteins and only about 10 % to other biosynthetic processes. More than 35% of the dry weight

stability of proteins in aqueous solution is essential to the understanding of their structure and function. The stability of a globular protein in aqueous solution can be determined by studying the disruption of its native structure, i.e., the process of denaturation[1]. In this process the native folded protein structure is converted into a form that is predominantly unfolded but can still possess some residual folded structure[2]. Consequently, the fully unfolded or random-coil state of protein, which
of Sub-cellular organelles Introduction Endomembrane system in Protein Synthesis The interior of a eukaryotic cell is packed with membranes so thin that they are totally invisible under the low resolving power of a light microscope. The endomembrane system fills the cell dividing it into compartments, channeling the passage of molecules through the interior of the cell, and providing surfaces for the synthesis of lipids and some proteins. The presence of these membranes in eukaryotic cells constitutes
Proteins are complex macromolecules that are formed by elements carbon, hydrogen, oxygen and nitrogen. Proteins composed of one or more polypeptide chains of amino acids. The main functions of proteins are to structure, support, protect, make movement, catalyst, transport and make hormones in human body. In the structural role, collagen and elastin provide support for connective tissue. Actin and myosin are proteins that involved in muscle contraction and movement. Haemoglobin is a protein that transports

The secondary structure prediction and tertiary structure prediction methods are also discussed in this chapter. 2.1 OVERVIEW OF PROTEIN STRUCTURE PREDICTION TECHNIQUES Proteins perform many biological functions and represent the building blocks of organisms. Basically there are 20 types of amino acids in proteins consists of different chemical
