help with this question Consider a 0.211 L solution of the amino acid aspartic acid (0.631 M), which has an alpha carboxylic acid group (pka = 2.10), an alpha amine group (pka = 9.82), and a carboxylic acid group in the side chain (pka = 3.86). If the titration is started at a very low pH, how many liters of 2.25 M NaOH would you need to add to reach the isoelectric point of the amino acid? Give your answer...

Need help with 27.46: According to its amino acid composition (I've provided the figure the question is referring too) lysozyme has an isoelectric point that is? Greater than 6, Less than 6, or about 6 are the possible answers. 9:58 ビ山 OBLEMS resulting derivative is treated with Fmoc-Val and DICHOBt, then with trifluoroacetic acid. (b) The cesium salt of Fmoc-Leu is allowed to react with the chloromethyl resin. The resulting derivative is then treated with Fmoc-Val and DIC HOBt, then...
Proteins are made from chains of amino acids. The amino acids are joined together by structures called peptide bonds. Draw the dipeptide that results when a peptide bond is formed between the two glycine molecules shown here. (Figure 1) Draw it as it would occur at the pHpH of most body fluids. Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. Include all...

can someone help me answer these 5 questions and figire this graph out please? Acid-Base Titration of a Weak Acid with a Strong Base: Determination of K. Introduction: You will be titrating a solution of a weak acid with 0.100 M NaOH, while monitoring the reaction using a pH meter. Weak acids have characteristic acid-ionization constants, K. The purpose of this lab is to use the titration to determine the value of this constant for the weak acid called “benzoic...
