26.2 氨基酸与亨德森–哈塞尔巴尔赫方程：等电点
根据亨德森–哈塞尔巴尔赫方程（第 20.3 节和第 24.5 节），如果我们已知溶液的 pH 和酸 HA 的 pK_{\text{a}}，就可以计算 [A^{\text{–}}] 的比值
1. According to the Henderson–Hasselbalch equation (Section 20.
According to the Henderson–Hasselbalch equation (Section 20.
2. Because the pH of the solution is much closer to pK_{\text{a
Because the pH of the solution is much closer to pK_{\text{a
3. In addition, we know that {[A}^{{–}}] + [HA] = 1.00 M Solvin
