Methylation

Turning genes on and off at appropriate times is the result of proper methylation. It is facilitated by supplementation with vitamins B6, B12, folic acid, and the digestive aids betaine and glycine. Lowering excessive cortisol levels also improves methylation. The easiest way to do that is by augmenting DHEA, which decreases body fat as well as age-related brain cell death associated with memory impairment. Only take DHEA under age-management practitioner's supervision

calculate pH of phosphoric acid

Question: adding 1/4 teaspoon of 10% phosphoric acid  to 19 litres of water, what will be the pH? Let's go through the calculations step by step. Step 1. Convert mass ( or volume) of 10% phosphoric acid to mole per litre ( mol/L) The above calculation shows that 1/4 tsp of H3PO4 acid is 6.97e-5 mol/L Step 2. Input this value to BATE (or other app) to calculate pH The answer: pH = 4.16, ie too acidic !? If you use pipette instead of teaspoon,  1 drop = 0.05ml. So 1/4 TSP means roughly 25 drops If you actually aim for pH 5.6 (which is optimum pH for mashing), conc will be 2.51 e-6, or 1/100 tsp , 0.044 ml, roughly 1 drop Let's roll back a bit. From  recipes of   BarleyWine , summer rye , hefe Gordon Strong suggested to use 1/4 teaspoon of 10% phosphoric acid, which is targeting pH of 5.5..... Discussion on  homebrewtalk  forum. However using online BF water calc , Sparge pH would be 4.6. but he also added 1 tsp of CaCl2. 2H20. Mash pH change from 5.7 t...
