Terpenoid cyclases catalyze the most complex reactions in biology, in that more than half of the substrate carbon atoms often undergo changes in bonding during the course of a multistep cyclization ...

Compounds are classified as acids, bases, and salts. Introduction to Acids, Bases and Salts: Compounds are classified as acids, bases, and salts based on the Arrhenius definition, and as acids or ...

Chemists have long known that catalytic Lewis acidic and Lewis basic sites on metal and metal oxide surfaces help spark a range of reactions that are important in industrial chemical and fuel ...

Building better batteries means understanding the chemistry of acids and bases. Now, scientists found that when a strong acid is mixed with water, the negatively and positively charged parts create an ...

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

Turmeric, the key ingredient in golden milk, contains a bioactive compound called curcumin. Curcumin exhibits antioxidant and anti-inflammatory effects, but not much of it passes into the bloodstream ...

Fundamental principles and concepts of chemistry, including stoichiometry; thermochemistry; atomic and molecular structure; solution chemistry, including acid-base chemistry; quantum theory; bonding ...

The 1970’s was the decade that illuminated the threat of acid rain to the citizens of the US. It had been known to exist several years before, but the sources of the problem did their best to suppress ...

The addition of NH 4 Cl to a solution of ammonia shows the effect of adding a common ion to a system at equilibrium.
