一般需知【体内钾的分布】人体内钾主要存于细胞内,占98%,其浓度为150毫当量/升,为细胞内液内的主要阳离子。细胞外液仅含有少量钾,但对于维持人体的正常生理功能却极端重要,正常人血浆中钾仅占总量的3.2%,其浓度为3.4～5.6毫当量/升。晚近的研究表明,细胞外钾主要以离子状态存在,但细胞内钾大约有2/3不是游离的钾,而是与蛋白质、糖或磷酸
Generally need to know 【Distribution of potassium in the body】 Potassium in the human body mainly in the cells, accounting for 98%, its concentration of 150 milliequivalents / liter, the intracellular fluid is the main cation. Extracellular fluid containing only a small amount of potassium, but to maintain the normal physiological function of the human body is extremely important, normal plasma potassium accounted for only 3.2% of the total, the concentration of 3.4 ~ 5.6 meq / liter. Recent studies have shown that extracellular potassium exists mainly in the ionic state, but about two-thirds of intracellular potassium is not free potassium, but rather is bound to protein, sugar, or phosphoric acid
