Question
1. Is aspartic acid and acid or base? 2. What is the ratio of charged/uncharged aspartic acid at pH 7.? 3. What is the pK for the carboxyl group of the side chain of glutamic acid? Is this group an acid or base? What is the ratio of charged/uncharged (ionized/unionized) glutamic acid at pH 7.1 4. Is the side chain of arginine an acid or a base? What is the ratio of charged/uncharged arginine at pH 7.52 5. 6. Is lysine an acid or base? What is the ratio of charged/uncharged lysine at pH 6.8? 7. So, basically, these four amino acid side chains are mostly a. charged b. neutral (circle the correct answer) at pH 7Explanation / Answer
According to the Chegg guidelines I'll answer the first question when more than one question is posted. Post them separately to get the answers.
1) Aspartic acid is acidic in nature.
It contains extra carboxylic acid group as the side chain.
Another example if acidic amino acid is glutamic acid.
Lysine, arginine and histidine are the basic amino acids and structure of hey contain NH3 group as the side chain part from N terminus.
