Whey protein

DNA codes for protein by protein synthesis. In protein synthesis, there are two major steps; transcription that creates mRNA and translation that translation mRNA to translate into protein. Transcription happens in the nucleus, after the process of transcription, mRNA molecule is then sent to the ribosome where the message is translated into specific proteins. This process is called gene expression. Millions of cells in the human body…

Q1) What secondary structures make up the large C-terminal domain of the Klenow fragment? Answer: The large C-terminal domain contains a six-stranded antiparallel β-sheet at the bottom of the cleft region and contains three α-helices on one side and four α-helices on the other side of the cleft region. Q2) Describe the three-dimensional structure of the large C-terminal domain of the Klenow fragment? Answer: The large C-terminal domain contains a significantly deep cleft, with a considerable…

fourteen different organisms. The data produced was an identification table, a sequence alignment diagram and a cladogram. In cladograms the branches are not representative of the evolutionary time that has occurred. Heat shock proteins (HSPs) are in a class of proteins called molecular chaperones. (Kiang, J.; G, Tsokos. 1998). They are present in both eukaryotes and prokaryotes, in the cytosol, mitochondria, endoplasmic reticulum and the nucleus. In humans they have a relatively long…

vegetarian diet is one lacking red meat, poultry and seafood. Whether or not vegetarianism is good for one’s health tends to be a controversial topic, as meat contains more essential nutrients than vegetables. Meat provides a higher-quality source of protein than vegetables because meat is packed with amino acids that vegetables do not supply. The type of iron in meat also absorbs better than vegetables which contributes to low iron levels in vegetarians. Due to these facts many believe that…

FPV is in the family Parvoviridae, which contains 26 species of virus that infect a broad host range, covering species from invertebrates to humans. Parvoviruses are small single stranded DNA viruses enveloped by a T=1 non-enveloped capsid protein. Replication of these viruses can only occur when the host cell is in S-phase of its mitotic cycle (15). FPV has a very small linear genome that is only 5 kilobases in length (4). The virus’s genome has specific sequences, similar to a TATA boxes, that…

Sarah Diaz Dr. Basu Bio 572 My Favorite gene One of my favorite genes that I have had the pleasure of working with is known as PROMININ-1, or PROM-1. One of the reasons why it exists as my favorite gene, is because the research lab that I am interning at studies this gene and its role in a very well known and unfortunate disease, biliary atresia. It also is one my favorites due to the fact that it has a lot of potential applications in studying other diseases or further research. These…

Specific activity is useful to know for a protein as it is a good indicator of an enzyme 's purity and quality. The Bradford assay measures total protein in the assay, and was calculated as 4.2mg/mL. The result was calculated from a set of four concentrations, of which there was a standard deviation of 1.3mg/mL and a standard error of 0.66mg/mL. These…

species owe their success to various forms of anti-freeze proteins. Within Northern Atlantic resident species, there are six classes of Anti-Freeze Proteins (AFPs), generally categorized by molecular size, structure and effectiveness. AFPs are a remarkable exhibition of convergent evolution – there are vast multitudes of AFPs, all present in species with no significant common ancestry. Additionally, there is no ‘common ancestry’ in the proteins themselves; some are fibrous, some are globular,…

Cell penetrating peptides are proteins or peptides that typically consist of 5-30 amino acids. These peptides are unique in that they are able to cross cell membranes and other barriers throughout the body such as the blood brain barrier, intestinal and nasal mucosa, and even skin. Using CPPs, scientists are now able to explore their potential as a means of transporting cargo into cells and across bio barriers. With their ease of preparation and generally nontoxic nature, CPPs have gained a…

diet. The RDA recommends we consume 0.8 grams of protein for every Kg that a person weighs. Food and Nutrition Board, Institute of Medicine. (2002) Proteins consists of amino acids, these are often referred to as its building blocks. Human beings have a biological requirement for amino acids and cannot synthesise 9 of the 20 most common. These 9 are called the essential amino acids and must be a part of our diet in order to make all the necessary proteins. Red meat has high amounts of these…
