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

Protein biosynthesis is the process by which biological cells generate new proteins; it is balanced by the loss of cellular proteins via degradation or export. Translation‚ the assembly of proteins by ribosomes‚ is an essential part of the biosynthetic pathway‚ along with generation of messenger RNA (mRNA)‚ aminoacylation of transfer RNA (tRNA)‚ co-translational transport‚ and post-translational modification. Protein biosynthesis is strictly regulated at multiple steps‚ and error-checking mechanisms

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

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

Protein Hydrolysis and Characterization Group 7 Niez‚ Robert Francis‚ *Orbin‚ Alfonso Ricardo* Parro‚ Athena Emmanuelle Peralta‚ Christian Department of Biological Sciences‚ University of Santo Tomas‚ Manila‚ Philippines • Abstract Hydrolyzed Protein is protein that has been hydrolyzed or broken down into its component amino acids. While there are many means of achieving this‚ two of the most common are prolonged boiling in a strong acid (acid-HVP) or strong base or using an enzyme such

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

You have to have enough carbs.” Find out if Janine is right. How does the nervous system use glucose? . Janine also said: “If you eat way too much protein and not enough carbs you can ruin your kidneys forever because of all the nitrogen you have to process breaking down the protein.” Find out if Janine is right about

Techniques for Isolation of Pure Cultures Objective : i. To perform the spread plate and the streak plate inoculation procedure for the separation of the cells of a mixed culture so that discrete colonies can be isolated. ii. To prepare a stock culture of an organism using isolates from the mixed cultures prepared on the agar streak-plate and/or the spread plate. Introduction : In order to be able to adequately study and characterize a certain microorganism‚ microbiologists need to separate
