NMN and Cell Membrane
We will examine the NAD+ molecule, its precursor nicotinamide monnucleotide and the debate over whether these molecules can pass through a cell membrane.
NAD+ is essential for cell function
Nicotinamide Adenine Dinucleotide is a redox-cofactor and also a signaling molecule. It regulates cellular function and survival as a response to environmental factors such as changes in nutrient intake or cellular damage. The age-related changes in NAD+ levels within the cell affect mitochondrial function, nutrient metabolism, circadian rhythms, immune and inflammation responses, DNA repair and cell division, protein to protein signaling, chromatin and epigenetics.
