Glycolysis - NADH - Pyruvate* - Redox

 >See d-biotin information below:

Glycolysis is a metabolic pathway that occurs in the cytoplasm of cells and is the first step in cellular respiration. It is a series of 10 enzyme-catalyzed reactions that convert glucose into pyruvate with the simultaneous production of ATP 1. Here is a simplified version of the pathway:

1. Energy investment phase: In this phase, glucose is converted to fructose-1,6-bisphosphate in a series of steps that use up two ATP molecules 2.
2. Energy payoff phase: In a series of steps that produce one NADH and two ATP, a glyceraldehyde-3-phosphate molecule is converted into a pyruvate molecule 2.

The amino acid carnosine plays a role in glycolytic flux, (it increases it). Carnosine is also a free radical scavenger.

Glycolytic flux is the rate of glucose metabolism through the glycolytic pathway 1. The glycolytic pathway is a metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process 1. The glycolytic pathway is a critical component of many biological processes, including energy production, and is highly regulated 2. Glycolytic flux has been implicated in a variety of disease states, including cancer and diabetes.

The following diagram illustrates the glycolysis pathway:

What is NADH

Nicotinamide adenine dinucleotide (NADH) is a coenzyme that plays a crucial role in metabolism by carrying electrons from one reaction to another 1. It is made up of two nucleotides joined through their phosphate groups, one containing an adenine nucleobase and the other containing nicotinamide 1. NADH is involved in redox reactions, where it acts as a reducing agent to donate electrons 1. It is also used in other cellular processes, such as adding or removing chemical groups to or from proteins 1. NADH is naturally produced by the body and is involved in generating energy 2. It is found in all living cells and is involved in many biological processes 1. Some people take NADH supplements to treat

 chronic fatigue syndrome, high blood pressure, high cholesterol, depression, Parkinson’s disease, and other conditions, but there is no good scientific evidence to support these uses 2.

NMN stands for nicotinamide mononucleotide. It is a molecule that serves as a precursor to NAD+ (nicotinamide adenine dinucleotide), which is an essential molecule for cell energy generation, DNA repair, and harmful oxygen-containing molecule (reactive oxygen species) disposal 1. NMN can be absorbed into the body and converted to NAD+ through chemical reactions involving electron gain/loss known as redox reactions 2.

NADH stands for nicotinamide adenine dinucleotide (NAD) + hydrogen (H). It is a coenzyme that plays a crucial role in metabolism by carrying electrons from one reaction to another 3. NADH is involved in redox reactions, where it acts as a reducing agent to donate electrons 3. It is also used in other cellular processes, such as adding or removing chemical groups to or from proteins 3. NADH is naturally produced by the body and is involved in generating energy 4. It is found in all living cells and is involved in many biological processes 3. Some people take NADH supplements to treat chronic fatigue syndrome, high blood pressure, high cholesterol, depression, Parkinson’s disease, and other conditions, but there is no good scientific evidence to support these uses 35.

There are no specific nutrients that are involved in the production of NADH. However, NADH is synthesized from nicotinamide adenine dinucleotide (NAD+), which is derived from vitamin B3 (niacin) 1. NAD+ can be synthesized from tryptophan, an amino acid found in many foods, including turkey, chicken, fish, and eggs 2.

NAD+ and NMN are two molecules that play a crucial role in metabolism and energy production ¹. NAD+ is an active coenzyme that takes part in numerous metabolic processes throughout the entire body ². NMN, on the other hand, is a precursor molecule to NAD+. This means NMN is converted to NAD+ in your cells through a chemical process ²³.

NMN is thought to be more easily absorbed by the body due to natural pathways in the cells that allow it to be absorbed and then converted to NAD+. NAD+ doesn’t have a direct way of entering the cells, so it must be converted to NMN or Nicotinamide Riboside (NR) before it can be absorbed and then once again converted into NAD+ once in the cell ²⁴.

Both NMN and NAD+ are crucial for cellular functions, including energy consumption and cellular repair. On the surface, their functions look the same but have some significant differences. NMN is thought to have more physical effects, and NAD+ is thought to have more effect on mental health and brain health ²⁴.

NMN supplements have been studied for their potential to increase NAD+ levels, improve cellular function, and reduce age-related cellular damage ¹. NAD+ injections are a suitable replacement for NMN. They contain the same molecules, but NAD+ has more metabolic, physiological, and psychological benefits with mild to no risk of side effects ⁵.

Biotin may play a key role in glycolysis - particularly d-biotin which is a different molecule than biotin.
