Approximately 40% of all known enzymes require helper molecules called cofactors to function correctly. These non-protein chemical compounds are essential for enzyme activity, assisting in the catalysis of biochemical reactions within living organisms. Understanding what are the two main types of cofactors is fundamental to comprehending how enzymes drive metabolism and support life.

Food enzymes, used for centuries in traditional practices like fermentation for bread and cheese, represent just one small but critical application of modern biochemistry in the food industry. Today, the scope of biochemistry in the food industry extends far beyond ancient techniques, revolutionizing how food is produced, processed, and consumed by applying molecular knowledge to improve quality, safety, and nutritional value.

In many fermentation processes, including winemaking, yeast (specifically *Saccharomyces cerevisiae*) consistently consumes glucose at a faster rate than fructose. This phenomenon often leads to stalled or sluggish fermentations, leaving a higher concentration of residual fructose in the final product. Understanding why fructose ferments slower than glucose is crucial for controlling the fermentation process effectively.

Did you know that about 70% of the world's population is affected by lactose malabsorption? For many, understanding what type of enzyme is available for the breakdown of milk is crucial for avoiding digestive discomfort caused by the inability to process milk's natural sugar.

The long-held belief in the one gene–one enzyme–one function paradigm has been overturned by a wealth of evidence showing that proteins often perform multiple, distinct tasks. This phenomenon, known as 'protein moonlighting,' showcases nature's ingenious ability to maximize functional diversity from a limited genetic blueprint.

Over a century ago, the discovery that trace amounts of certain organic compounds were vital for life led to the concept of vitamins. Today, we know this happens because vitamins are necessary for enzyme activity, acting as key helpers known as coenzymes to facilitate countless biochemical reactions in every cell.

In a process that begins immediately upon chewing, salivary amylase starts the chemical breakdown of starches. This makes amylase the primary enzyme that digests starch into disaccharides, a crucial first step in carbohydrate metabolism that often goes unnoticed.

Starch, a complex carbohydrate made of glucose units, is one of the most abundant polysaccharides found in nature, serving as a primary energy reserve for plants. Starch hydrolysis is the process that breaks this large molecule down into smaller, more usable sugars, a conversion essential for life and industry.

Over 100 enzymatic reactions in human metabolism, primarily related to amino acid pathways, require the coenzyme pyridoxal phosphate. Understanding what are the coenzymes of amino acids is crucial for comprehending the metabolic processes that sustain life, from synthesis to degradation.

Chewing a starchy food like bread for a long time can make it taste slightly sweet, a phenomenon caused by the digestive enzyme amylase starting its work right in your mouth. This crucial enzyme is the body's primary tool for breaking down complex carbohydrates into simpler sugars that can be absorbed and used for energy.
