Practical 3: Proteins Introduction: ‘Protein’ also an important food component‚ we commonly take in from our diet. In this experiment we have studied a certain property of protein‚ i.e.‚ protein can be denatured by various factors. A. Denaturation of egg white Results: Egg white sample in water baths | Test tube | temperature | Observations | 1 | 60°C | Took 7minutes and 15 seconds to turn white and form white participate. | 2 | 80°C | Took 2minutes and 20 seconds to turn white

In this report‚ the concentration of total protein and albumin were calculated with the interpretation of a standard curve. To determine the concentration of total protein in human serum‚ a total protein assay was performed by using the Biuret reagent. Proteins react to this compound because it contains two amide bonds. When the Biuret reagents is introduced to a sample of protein‚ it forms a blue or violet complex. The concentration of albumin in human serum is determined by using the Bromocresol

Protein Article Research SCI/241 August 1‚ 2013 Dr. Theodore Keneklis Protein Article Research Proteins are made up of amino acids‚ and in our bodies we have proteins that “are part of every cell‚ tissue‚ and organ in our bodies” (Centers for Disease Control and Prevention: Protein‚ http://www.cdc.gov/nutrition/everyone/basics/protein.html). There are complete proteins which are made up from animals. These kinds of proteins are found in meat‚ poultry‚ fish and even cheese. A complete

The protein in consumed food turns into amino acid. The amino acid is used later replinish the proteins used. Proteins have two structures. the first and primary structure of protein is the sequence of the amino acid in the protein (Kim‚ 2005). The amino acid

Protein synthesis is one of the most fundamental biological processes. To start off‚ a protein is made in a ribosome. There are many cellular mechanisms involved with protein synthesis. Before the process of protein synthesis can be described‚ a person must know what proteins are made out of. There are four basic levels of protein organization. The first is primary structure‚ followed by secondary structure‚ then tertiary structure‚ and the last level is quaternary structure. Once someone understands

Proteins play an important role in the human body. The DNA molecule controls the synthesis of proteins. The DNA contains genes which are sequences of nucleotides and bases. Proteins are used for growth and repair. Proteins are made up of amino acids linked together by peptide bonds. Firstly ’amino acid synthesis ’ is the set of biochemical processes by which the various amino acids are produced from other compounds. The substrates for these processes are various compounds in the organism ’s diet

Denaturing of Proteins Research Paper Abstract: Introduction The experiments the objective is to determine‚ the possible measures of the denaturation process of several proteins by using a home based temperate The necessary applications of this experiment are to compile all the possible measures of the denaturation process in understandable units and explainable means. Other methods possible for research are by using a

Protein synthesis is the process whereby proteins are produced‚ or synthesized‚ in living things according to "directions" given by DNA (deoxyribonucleic acid) and carried out by RNA (ribonucleic acid) and other proteins. As suggested earlier‚ this is an extraordinarily complex process that we do not attempt to discuss here. Following synthesis‚ proteins fold up into an essentially compact three-dimensional shape‚ which is their tertiary structure. DNA contains the instructions for a cell’s structure

4A.2 RRL 4A.2.1 Coagulation of Proteins Coagulation of protein refers to sticking together‚ like a blood clot‚ usually as a result of denaturation or coming out of solution due to abnormal ionic strength or a change of solvent. Definite characteristics of the proteins are changed when they are coagulated‚ among which is loss of solubility in water and dilute salt solutions. In some instances and under certain conditions the coagulation process may be reversible. (Campbell‚ et.al‚ 1979) 4A.2.2

in the fragmentation of the DNA. Protein glycosylation may be an additional damaging factor . In the attempt to repair DNA‚ poly(ADP-ribose) polymerase (PARP) is overstimulated. This diminishes cellular NAD+‚ and subsequently ATP‚ stores the depletion of the cellular energy stores ultimately results in beta cell necrosis. Although streptozotocin also methylates proteins ‚DNA methylation is ultimately responsible for beta cell death‚ but it is likely that protein methylation contributes to the functional
