The terms reactant and product can be used to describe constituents of individual enzymatic reactions or entire metabolic pathways. Reactants (or 'substrates') are the starting materials for a reaction, In the generic reaction shown below, A and B are the reactants. C and D are the products. CO2 and RUBP are the reactants in this reaction, Rubisco is the enzyme, and the product is two molecules of 3PGA. We can also refer to the reactants and products of entire metabolic pathways, such as of the light-independent reactions.
A. PLASTER IS A TIME TESTED PRODUCT: Plaster has been used as a swimming pool surface coating for the past 50 years. This experience has shown that plaster is a durable surface that can stand up to the environment of proper pool water chemistry.
ABCs of Pool Water Chemistry. There are five chemical levels that every pool owner needs to keep track of: FC - Free Chlorine - A sanitizer which keeps your pool water safe and free of germs. Chlorine must be constantly replenished. (level depends on CYA) PH - Acidity/Alkalinity - Needs to be kept in balance to prevent irritation and protect the pool equipment.
