- Given that C6H11COOH has a pKa = 4.8 and C6H11N + H3 has a pKa = 10.7, what pH would you make the water layer to cause both compounds to dissolve in it?arrow_forwardCarbonic acid has a pKa of 6.1 at physiological temperature. Is the carbonic acid/bicarbonate buffer system that maintains the pH of the blood at 7.4 better at neutralizing excess acid or excess base?arrow_forwardH2O2(l) deltaG=-120.4 H2O(l) deltaG=-237.1 O2 (g) deltaG=0arrow_forward
- The pkb of methylamine, CH3NH2, is 3.36. Calculate the pka of its conjugate acid, CH3NH3*. pka =arrow_forwardBicarbonate (shown below) functions as a conjugate base within the plasma's bicarbonate buffer system. Bicarbonate also was important for the: OI (10 OH O process of lipogenesis (triacylglycerol synthesis) rate-limiting step in fatty acid metabolism O process of lipolysis (triacylglycerol metabolism) committed step in fatty acid synthesis J Bicarbonate (shown below) functions as a conjugate base within the plasma's bicarbonate buffer system. Bicarbonate also was important for the: C10 OH O process of lipogenesis (triacylglycerol synthesis) Ⓒrate-limiting step in fatty acid metabolism O process of lipolysis (triacylglycerol metabolism) committed step in fatty acid synthesisarrow_forwardProvide an explanation without using the pka values : Why is phenol stronger acid than butanoic acid?arrow_forward
- Carnosine, found in muscle and brain tissue, acts as a buffer to neutralize small amounts of acid. The pKa of the conjugate acid of carnosine is close to 7.0. What is its structure?arrow_forwardWhat happens when ZnCl2 is dissolved in acetone?arrow_forwardGive the polarity, melting point, boiling point, solubility, and state at room temperature of the following: Linoleic acid Tripalmitin Triolein Phosphatidylcholine(28:0) Phosphatidylinositol(34:1) Phosphatidylserine(36:2) Phosphatidylethanolamine(38:6) Cholesterolarrow_forward
- Explain the difference in Pka of the following acids, CH3CH2OH and FCH2CH2OH?arrow_forwardUse curved arrows to illustrate how the following decarboxylation occurs in the presence of an acid HA. This reaction constitutes one step in the biosynthesis of the amino acid tyrosine.arrow_forwardA glycylglycine buffer is made to a pH of 8.45 at 25 ∘C then warmed to 37 ∘C. The pH of the solution changes because of the pKa changes. Glycylglycine has a p?a=8.26 and a Δp?a/Δ?=−0.026 °C−1. Calculate the pH of the buffer at 37 ∘C.arrow_forward
