The side chain for Histidine has a pKR of around 6.0. Histidine's alpha carboxyl and alpha amino groups have pKas relatively similar to lysine's. What is the charge of ONLY the histidine side chain at pH 4? What is the charge of the entire Histidine molecule at pH 4.0?
Please explain in detail if possible. Thank you

The lysine side chain has a pKR of about 10. Using the Henderson-Hasselbalch equation, solve for the ratio of [A-] / [HA] that corresponds to the ratio of deprotonated side chains / protonated side chains when pH 10.7. Please calculate the percentage of lysine's side chains that are deprotonated at pH 10.7. Please explain in detail if possible. Thank you.
Functional group pK -carboxyl 2.3 -amino 9.0 E carboxyl side chain 4.3 K side chain 10.5 H side chain 6.0 R side chain 12.5 1. What is the charge on Valine at pH 3.5? 2. What is the charge on Lysine at pH 9.7?
If you have 4 Lysines, the side chain of Lysine has a Pka value of around 11, you are at pH of 4, are you going to take a proton off or to add? What is the net charge of these four Lys? What kind of ion exchange chormatography would you use?

TORENTO CONSTRUCTION: ETHICAL CONTRACTING On December 27, 2010, Cary Holmes, manager of the Supply Chain Management (SCM) group at Torento Construction Inc. (NCG), was in his office in Torento, Ontario, trying to organize the thoughts running through his head as a result of a recent bidding to save operating costs at NCG. There was no problem in terms of the final outcome; in fact, the bid was going to result in cost savings of 25 per cent, which was exactly...
Risk management in Information Security today Everyday information security professionals are bombarded with marketing messages around risk and threat management, fostering an environment in which objectives seem clear: manage risk, manage threat, stop attacks, identify attackers. These objectives aren't wrong, but they are fundamentally misleading.In this session we'll examine the state of the information security industry in order to understand how the current climate fails to address the true needs of the business. We'll use those lessons as a foundation...
HDT Truck Company HDT Truck Company has been located in Crown Point, Indiana, since 1910. Its only products— large trucks—are built to individual customer specifications. The firm once produced automobiles but dropped out of the auto business in 1924. The firm nearly went out of business in the late 1930s, but by 1940 its fortunes were buoyed by receipt of several military contracts for tank retrievers—large-wheeled vehicles that can pull a disabled tank onto a low trailer and haul it...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
