Ultimately the albumin and gelatin solution were found to contain proteins due to the change color to a violet color after the addition of the biuret solution and the glucose solution, water and the unknown solution did not contain peptide bonds because they remained blue after the addition of biuret solution. From this experiment it can be shown that the unknown solution does not contain protein. Introduction This lab was performed to test multiple solutions for peptide bonds signaling the presence of proteins in solutions with the use of biuret solution. The Environmental Encyclopedia defines a peptide as â€Å"A chemical compound consisting of two or more amino acids joined to each other through a bond between the nitrogen atom of one amino acid to an oxygen atom of an adjacent amino acid (â€Å"Peptides†,2011). Merriam Webster dictionary defines a protein as â€Å"any of various naturally occurring extremely complex substances that consist of amino-acid residues joined by peptide bonds, contain the elements carbon,Show MoreRelatedAnalysis Of Adipose Derived Induced Pluripotent Stem Cells4532 Words   |  19 PagesiPSC’s that have differentiated into pancreatic ÃŽ ²-cells will be comparable profile to murine and human pancreatic ÃŽ ²-cell controls.

According to his research, a treponeme may curve slowly or quickly, forming small or large arcs of circles, or it may bend so sharply in the middle as to form a right angle and then rather quickly resume its original straight corkscrew shape. 7 The axial filament is an internal flagella found only in the spirochetes. Axial filaments are composed of from 2 to over 100 axial fibrils (or endoflagella) that extend from both ends of the bacterium betweenRead MoreRna Interference Regulates Gene Expression9725 Words   |  39 PagesRNaseIII domains lead to an unparalleled scission that generates a 2 nt 3’ overhang as a characteristic â€Å"signature† of Dicer procession. The active center of RNase III is comprised of 3-4 acidic residues and two Mg2+ ions coordinated by phosphodiester bonds (Figure. 2b)(Denli et al. 2004; Macrae et al. 2006; Park et al. 2011). The N-terminal superfamily 2 helicase domain was originally implicated in unwinding complicated RNA substrates (Zou et al. 2009). New evidence suggests that the DExD/H and helicase
