(Created page with "== Overview == A coenzyme is a non-protein chemical compound or metallic ion that is required for an enzyme's activity as a catalyst, a substance that increases the rate of a chemical reaction. Coenzymes are considered "helper molecules" that assist in biochemical transformations. The rates at which these happen are often determined by the availability of coenzymes. == Function == Coenzymes are primarily responsible for transferring a group of atoms from on...") |

NAD+ is a coenzyme found in all living cells. It is a dinucleotide, meaning it consists of two nucleotides joined through their phosphate groups. NAD+ is crucial for redox reactions, carrying electrons from one reaction to another. This is important in energy production, specifically in the production of ATP, the main energy source for metabolic functions. | NAD+ is a coenzyme found in all living cells.
