In biological systems, reactions often happen on small scales, involving small amounts of substances, so those substances are routinely described in terms of milliequivalents (symbol: officially mequiv; unofficially but often mEq or meq), the prefix milli- denoting a factor of one thousandth (10 ). Very often, the measure is used in terms of milliequivalents of solute per litre of solution (or milliNormal, where meq/L = mN). This is especially common for measurement of co… Web6 jun. 2024 · Each 1 g of arginine hydrochloride provides 4.75 mEq chloride. Note: Dosing based on arginine hydrochloride product.
