Did you know that digestion begins the moment food enters your mouth, not when it reaches your stomach? The first nutrient broken down chemically is carbohydrates, specifically starches, which are targeted by an enzyme in your saliva.

Did you know that the average human body recycles a substantial portion of its proteins each day? The complete process to break down amino acids begins with proteolysis, the breakdown of the larger protein chain, and concludes with deamination, the removal of the amino group from the individual amino acid.

Yes, pyruvate can absolutely be used to make alanine, a process that is a fundamental component of amino acid and carbohydrate metabolism. This conversion, known as transamination, is a key biochemical reaction that links glycolysis with amino acid biosynthesis and is vital for transporting nitrogen out of muscle tissue. The conversion highlights the flexibility and interconnectedness of the body's metabolic pathways.

Catalase, a powerful antioxidant enzyme found in nearly all living organisms exposed to oxygen, plays a crucial role in cellular defense. As we age, our body's natural production of catalase can decline, increasing oxidative stress and potentially contributing to age-related issues. Certain foods contain or stimulate the production of catalase, making diet an important factor in maintaining healthy levels.

Over 10,000 different proteins are at work inside you right now, forming the molecular machinery that powers life. These complex molecules perform a breathtaking array of tasks, and understanding the vital functions of proteins is key to grasping how your body operates and stays healthy.

Proteins are among the most abundant organic molecules in living systems and are more diverse in function than other macromolecules. Understanding what are the functions of different types of proteins is crucial for comprehending how biological processes occur at a cellular level.

Over 90% of the protein ingested is broken down into its basic building blocks, known as amino acids, during digestion. This fundamental biological process, called proteolysis or hydrolysis, is vital for the body's ability to use dietary protein for building, repairing, and regulating tissues and cells. The breakdown of proteins is a multi-step process involving specific enzymes and conditions in the digestive tract.

Food spoilage can become noticeable when microbial populations reach about 10 million cells per gram, a change rooted in biochemistry. Understanding what is biochemistry in relation to food helps explain why this happens and reveals the chemical processes shaping our meals, from cooking to digestion.

According to the National Institutes of Health, the scientific study of human nutritional requirements began less than 100 years ago, and modern biochemistry explains how our bodies use the nutrients from food at a molecular level. This critical field helps us understand not only how food nourishes us but also how it influences our health, disease prevention, and overall wellness.

Every cell in the human body contains protein, a fact that underscores its fundamental importance. While often associated with building muscle, the primary role of proteins in the body is far more extensive, involving growth, repair, transport, and a vast array of life-sustaining functions.
