Protein Article Research SCI/241 September 27‚ 2012 Roberta Harbison Protein Article Research Protein is an essential part of a healthy diet. It is made of different combinations of 20 different amino acids. Protein is found in every cell‚ tissue‚ and organ of the body. It is important to consume an adequate amount of protein because our bodies are constantly using the protein we digest to make more amino acids. Some amino acids cannot be produced by the body and it is essential that

The Role of DNA in Protein Synthesis DNA is found in the cells nucleus. It is part of the chromosome of the cell. DNA is the molecule that controls the making of protein. Protein is used for the growth of cells and organisms and also for the repair of cells. Protein is also used as an enzyme to speed up reactions in the body. Because of this DNA is able to control the whole organism. With out DNA and its ability to make protein the cells and eventually the whole organism would die

assumptions about her protein needs are unrealistic based on her current weight. Erin’s protein consumption is too low for her weight. This is roughly 13% of her kcalorie intake which is closer to the lower end of the ranges of 10-35 percent. This is unrealistic because she is not consuming enough calories of protein for her weight. If you calculate her weight by height you can clearly she needs more protein. Erin’s weight 118lbs /2.2ib/kg= 54 kg‚ so know take 54kg x 0.8g/kg= 43.2g protein. (Understanding

Alka-Seltzer is one of the world’s best known antacids. Its main function is to absorb excess stomach acid. II. MATERIALS: * Tap Water - Warm Water * Cold Water - Salt Water * Acidic Water -5 cups (250 mL of water in each cup) * A whole Alka-Seltzer tablet III. HYPOTHESIS: My hypothesis is that the Alka-Seltzer tablet

gene that codes for a protein called Cytochrome C. This protein is important in releasing energy from food. Scientists study similarities such as the gene that codes for Cytochrome C in hopes to learn more about the universal genetic code and the relationship between living organisms on Earth. Procedure: The charts below lists a portion of the amino acids found in the Cytochrome C protein of several different organisms. Use the chart to compare the amino acid sequence in humans to the sequences of the other organisms listed

Experiment 2 Quantification of Proteins in Solution by Spectrophotometer Lab bench# 1 Introduction: Absorption spectroscopy is a common method for finding the concentration of proteins or protein complexes in a solution. Proteins absorb light at specific wavelengths and can be defined by the equation A = log (Io/I). This equation states that an absorbance at a specific wavelength‚ A is equal to the log of the ratio of incident light intensity (Io)‚ to transmitted light intensity (I). A

The two unknown ones were identified by comparing the distance they travelled up the chromatography paper and their Rf values to the corresponding values of the other eight known amino acids. The unknown amino acids identified were Glycine and Methionine. Introduction Proteins in cells are important in many ways. There are different types of proteins such as contractile proteins‚ enzymes‚ hormonal proteins‚ structural proteins and transport
