According to the Linus Pauling Institute, Vitamin C is a potent reducing agent that readily donates electrons to other molecules. This unique chemical property makes vitamin C the primary vitamin that functions as an electron donor in the human body. In doing so, it protects vital molecules from damage and supports numerous enzymatic processes.

Iron is an essential mineral for most forms of life, and in biological systems, it exists in two primary oxidation states, ferrous (Fe2+) and ferric (Fe3+). While ferrous iron is crucial for oxygen binding, the role of Fe3+ in the body is equally vital, primarily revolving around the safe transport, storage, and controlled release of this potentially toxic element.

According to the National Institutes of Health, the functional cofactors derived from niacin are nicotinamide adenine dinucleotide (NAD+) and its phosphorylated form, nicotinamide adenine dinucleotide phosphate (NADP+). These vitamin B3 derivatives are integral to all cellular life, participating in hundreds of enzymatic reactions across all living organisms.

Over 95% of the riboflavin (vitamin B2) in our bodies is in the form of its coenzymes, flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN). This essential nutrient, often referred to as riboflavin, does not function directly but is the building block for these powerful coenzymes that are indispensable for human health.

Over 1,000 enzymes are known to use the coenzyme NADH, showcasing the critical role these molecules play in countless biological processes. This article explores what type of reaction is a coenzyme involved in, clarifying its function beyond being a mere catalyst helper.

In living cells, coenzymes are crucial for accelerating biochemical pathways, with certain B vitamins serving as key precursors. These organic molecules bind to enzymes to enable and participate in catalytic events, which explains what the reactions of coenzymes are and why they are so fundamental to life.

Recent research confirms that NAD+ levels naturally decline with age, influencing many age-related health changes. This critical molecule, however, is often confused with the general term NAD, leaving many to wonder, 'Are NAD+ and NAD the same thing?' The short answer is no; one is a specific form of the other, and understanding the distinction is vital for grasping its biological role.

Vitamin B3, also known as niacin, is involved in over 400 enzymatic reactions, a remarkable fact highlighting its central importance to metabolism. A deeper look at what is the biochemical function of vitamin b3 reveals its critical role in energy production, DNA repair, and numerous other vital cellular processes.

The element iron, represented by the symbol Fe, can exist in more than one oxidation state, with the +2 and +3 states being the most common. While both ferrous and ferric refer to iron, they are not the same thing, with the key distinction lying in the number of electrons each ion has lost. This fundamental chemical difference leads to significant variations in their characteristics, from solubility and color to their roles in biological systems and industrial processes.

While most people know Vitamin C as a powerful antioxidant, capable of neutralizing harmful free radicals, it exhibits a surprising and less-understood dual nature, acting as a pro-oxidant or oxidizing agent under specific circumstances. This capacity to both reduce and oxidize is what defines its complex role in human biology and its potential for varied effects, especially concerning supplementation and cellular health.
