9/4/2014 Fillers within Protein Supplements Local gym enthusiasts are trying to reveal if certain new dietary supplements will actually help them gain muscle mass by providing high levels of protein. Before the users consume the new supplements they want to know if they are indeed true protein supplements or if the manufacturer used fillers as a mean to make more profit. “Do the new supplements contain fillers such as sugar and starch or are they pure protein?” This is important

Pre-Reading Notes (Very Short Introduction - Chapter 5; Fundamentals of Forensic Science – Chapter 11): • Red and white cell blood antigens are polymorphic: they exist in more than one form and everyone inherits one or more forms of each of them • A successful DNA profile makes it possible to reach a conclusion that a DNA sample came from a specific individual‚ giving law enforcement and forensic science a new‚ powerful identification tool that complements fingerprints and other methods of identification

of the isomerase domain from a spliceosome-correlated cyclophilin‚ PPWD1 which is known as peptidylprolyl isomerase domain and WD repeat containing 1 or peptidylprolyl isomerase containing WD40 repeat‚ has been solved to 1.65 A ˚. PPWD1 acts as a protein-coding gene and its related pathways are mRNA splicing. An important paralog of this gene is PPIL2. This polypeptide encodes an N-terminal WD40 repeat domain as well as a C-terminal domain homologous to Cyps. PPWD1 was previously

PROTEINS AND NUCLEIC ACIDS 28/11/13 Qn. Which two of the four macromolecules do you believe to be the most important for life? Give evidence to support your suggestion (include a full description of the macromolecules you describe both in terms of structure and function) Introduction All the four macromolecules=lipids‚ proteins‚ carbohydrates and nucleic acids= are essential for the functioning of an organism ’s body (Campbell‚ biology). They work hand in hand to help us survive. For example

Biology II Step 1: How will you identify the “vital” cellular protein that the virus targets for degradation? (Hint: think proteomics). (3 pts.) First‚ since we know the viral RNA sequence and its targeting protein‚ we can investigate it in bioinformatics database‚ and can acquire some clues or hints about the target proteins. From the bioinformatics database‚ we might be able to find its structure‚ similarity with other proteins‚ functions‚ and binding domains. In other words‚ we can get some
