Beta-nicotinamide is integral to the synthesis of nicotinamide adenine dinucleotide (NAD+), a coenzyme that is essential for various metabolic reactions. NAD+ is involved in catabolic pathways that help convert food into energy, allowing cells to generate ATP—the energy currency of the cell. By facilitating the conversion of nutrients into usable energy, beta-nicotinamide supports vital functions, including DNA repair, cell signaling, and the regulation of metabolic processes.


Once an API is identified, formulating it into a usable medication involves the incorporation of excipients. Excipients are inactive substances that serve as carriers for the API. They play several key roles in drug formulation, including improving the stability and bioavailability of the active ingredient, aiding in the manufacturing process, and ensuring the drug is easy and pleasant for patients to consume. Common excipients include fillers, binders, disintegrants, lubricants, and preservatives, which collectively support the API in achieving its therapeutic goal.

Cationic polymers are positively charged macromolecules that can interact with negatively charged particles, including contaminants, organic matter, and colloids present in water. This charge-based interaction is fundamental to their effectiveness in water treatment processes. The positive charge of cationic polymers allows them to bind with negatively charged surfaces, facilitating the aggregation and removal of suspended solids and organic impurities.

Coagulation is a vital process used in water treatment to remove suspended particles and clarify water. Common coagulants include aluminum sulfate (alum), ferric chloride, and polyaluminum chloride. These chemicals work by destabilizing particles in the water, allowing them to cluster together (or coagulate) so they can be removed through sedimentation or filtration. Coagulants are particularly important in treating surface water sources, which often have higher turbidity levels.
