Mathematically, the pI for an acidic amino acid is the average of pKa 1 and pKa R (the pKa of the dissociable proton in the R group); for a basic amino acid, it is the average of pKa 2 and pKa R.here is no dissociable proton in the R group. This type of amino acid is called a âsimple amino acidâ. A simple amino acid is electrically neutral under physiological conditions. NOTE: Under this definition it is possible to have a simple amino acid which is triprotic.
Sent through a supposedly secure channel devoted to peace negotiations (a transatlantic cable belonging to Scandinavia) on January 19th 1917, the 'Zimmermann Telegram' â often called the Zimmermann Note-was a memo sent from the German Foreign Minister Arthur Zimmermann to the German Ambassador to Mexico.
(Answer #69). The United States entered World War 1 when they had a note given to them from the British that was from Germany. It was a note to Mexico, called the Zimmerman Note. Germany promised Mexico the land that America took from them earlier (like Texas and Arizona) if they helped Germany win the war.he United States entered the war because of the Germans' decision to resume the policy of unrestricted submarine warfare, and the so-called Zimmerman telegram, intercepted by the British, in which Germany floated the idea of an alliance with Mexico.
