Question Answer
What types of molecules are shown? Carbohydrates (saccharides)
Triacylglyceride or Triglyceride
-1 of the 2 acidic AA's -2 CH2 groups & COO- -Negatively charged
1 of the 3 basic AA's -Positively charged Side chain pka (6) very close to physiological pH of 7
1 of the 3 basic AA's positively charged R group = 4 CH2s + NH3
1 of the 2 Acidic AA's -one CH2 then COO- group -Negatively charged
1 of the 3 basic AA's Positively charged -3CH2s + a lot of amines
Polar and Neutral one of only two AA's w/sulfur group forms disulfide bridges
Polar and neutral -Amidic -highly polar and partially charged 2CH2s + amide
Polar and neutral -Amidic -highly polar and partially charged 1 CH2 + amide
polar and neutral ring + OH
Polar and neutral CH2 + OH
polar and neutral CHCH3 + OH
nonpolar neutral ONLY ACHIRAL AA
neutral nonpolar kind of looks like an "L"
nonpolar and neutral upside down V
nonpolar and neutral just a CH3 group
nonpolar neutral CH2 then upside down V
neutral and nonpolar 1 of only 2 AA's with Sulfur group Start codon
nonpolar and neutral unique with ring and lack of H (forms kinks)
nonpolar and neutral CH2 + benzyl ring
nonpolar & neutral only AA w/2 rings
Kw = ? pKa = ? Kw = 1X10^-14 pKa = -log (Ka)
What is the Henderson--Hasselbach equation? pH = pka + log ([A-] / [AH])
