The building blocks of proteins and enzymes are molecules formed by carboxyl acids attached to amino groups (-- NH2), known as amino acids. Most protein structures consist of combinations of only about twenty of the most commonly found amino acids....

Enzymes are complex proteins that act as catalysts for the countless biochemical reactions that keep humans, animals, plants, and microorganisms alive. Constituents of every living cell, enzymes have relatively large molecules that contain one or more...

Enzymes are molecules that act as critical catalysts in biological systems. Catalysts are substances that increase the rate of chemical reactions without being consumed in the reaction. Without enzymes, many reactions would require higher levels of...

Enzymes are proteins that catalyze (i.e. accelerate) chemical reactions.[1] In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, the products. Almost all...

Dr. Arthur Kornberg, whose test-tube synthesis of DNA earned him the Nobel Prize in 1959, died of respiratory failure Friday at Stanford Hospital, the hospital said. He was 89.Kornberg, an active professor emeritus of biochemistry at Stanford University's School of Medicine, shared the Nobel Prize...

Describes many commercial uses of enzymes, including detergents, leather, antibiotics and fructose production.

A report on an experiment to determine how temperature affects the activity of an enzyme. The hypothesis tested is that the higher the temperature, the faster the enzyme's reaction.

Explains a lab experiment which answers why and how temperature, ph, and concentration affect the chemical reaction of enzymes and substrate.
