Erwin G Communication 17 September‚ 2012 Informative Speech: Whey Protein I. Introduction a. Muscles!! Everyone wants them; guy’s wants big arms and girls wants nice toned bodies. But they aren’t easy to build. Trust me I know. b. Having the opportunity last semester to take a weight training class to try and get more muscle and bulk up I realized I would need some sort of supplement to help me build more muscle. I also learned that it takes a good workout

BENEFITS OF WHEY PROTEIN IN FITNESS For centuries people have been using whey proteins for their beneficial health properties. Whey is derived from milk and is the by product of cheese production. Today it has found its place in nutrition as it offers optimal health and enables good fat burning. It is a low fat‚ low calorie and low carbohydrate food that is placed low on the glycemic index (GI) Scale. Replacing high fat and high calorie meals with this protein will melt the fat away because the

Relationships of Proteins Proteins are a group of organic compounds whose molecules consist of carbon‚ hydrogen‚ oxygen‚ nitrogen and sometimes sulfur atoms. They are condensation polymers of amino acids that are joined by strong peptide bonds. There are 20 different types of amino acids available‚ and the different combinations of these amino acids give it different structures and specific functions to it. Below in this essay‚ will illustrate the how different structure of a protein is related to

To purify the protein in the cell lysate from lab 1 through nickel affinity chromatography. Protein purification should result in only one type of protein ideally‚ which is the protein of interest‚ wt-DHFR and mut-DHFR in this case. A pure protein allows for further analysis on the protein to be conducted‚ such as its concentration (Bradford assay)‚ its molecular weight‚ and its biological activity. 2.

have for protein synthesis? Explanation: The mRNA encodes the amino acid sequence of a protein. During the translation‚ ribosomal RNA combines with other proteins to form a ribosome which amino acids are transported to the ribosome. The combination of mRNA and tRNA converts the mRNA into the amino acid sequence of the protein. Did the two mutations result in a change in the final proteins? If so‚ describe the change. Response/ explanation: A change took place in the final proteins because

1) Homeostasis is the condition in which the body maintains a. changing state‚ within an unlimited range. b. an equilibrium point that can change over a narrow range that is compatible with maintaining life c. an equilibrium change that balances external and internal environment such that values of each are equated 2) Anabolism is the a. breakdown of matter. b. expulsion of matter. c. synthesis of matter. d. All of the answers are correct. 3) The sum

genetic information and copies itself (replication) to pass on the information • Contains genes (instructions to make proteins) • Instructs cell’s activities DNA Structure • DNA is a polymer of nucleotides • Chromosomes (DNA strand + associated proteins ie. Histones wrap DNA around like a spool = condensed chromatin) ↓ genes (sections of a chromosome that codes for a protein) ↓ nucleotides (3 parts: phosphate‚ deoxyribose sugar‚ and nitrogen base) • • • Double helix shape - Held together

question ask is‚ how big is my protein footprint? It also asks‚ does a meat rich diet have a negative impact on our environment? And does it contribute to global warming? With a very small percentage of Americans following a vegetarian diet. I will say that my protein footprint is about the same as the majority of the US population. I understand that a good source of protein can be found in nuts‚ black beans and lentils. However the number one source of protein in a US household‚ comes from

Produced by cell clusters in the pancreas called the Islets of Langerhans‚ insulin is a hormone that regulates glucose concentration in the blood. It is a protein synthesised and stored by beta cells‚ which secrete it in surges responding to changes in glucose levels. (Hardin‚ Bertoni and Kleinsmith‚ 2012) Fig 1.

see looking at the Total Protein column on Table 3‚ the most effective step with regard to the percent of remaining protein removed was affinity chromatography because it was able to remove 98.6% of the remaining proteins. In comparison to 81.93% removed during the 65% ammonium sulfate precipitation and 81.3% during the size exclusion. This means that the affinity chromatography removed a big percentage of contaminating proteins. However‚ removing this huge amount of protein left us with a small amount
