Answer: pH = 2.72
Explanation:
Calculate the pH of 0.010 M HNO2 solution. The K, for HNO2 is 4.6 x 104
The polarity and acid/base character of each R group is the main factor determining the characteristics of an amino acid.
There are four types of R groups:
• <em>nonpolar</em>, e.g., CH₃ in alanine
• <em>polar</em>, e.g., CH₂OH in serine
• <em>acidic</em>. e.g., CH₂COOH in aspartic acid
• <em>basic</em>, e.g., CH₂(CH₂)₃NH₂ in lysine
The R group determines whether an amino acid is acidic, basic, or neutral.
However, the nature of the R groups is the major factor that determines <em>the 2° and 3° structures</em> of polypeptides and proteins.
The flying dinosaurs becoming extinct was the reason they were not found in rocks that are younger than those formed during the Mesozoic era.
