NAD stands for nicotinamide adenine dinucleotide. From single-cell organisms like bacteria to sophisticated multicellular ones like primates, NAD is one of the most abundant and crucial molecules. Basically, without NAD, we would be on the fast track to death. The molecule is a linchpin to the function of the generators of cells - mitochondria. NAD not only helps convert food to energy but also plays a crucial role in maintaining DNA integrity and ensures proper cell function to protect our bodies from aging and disease.
NAD+ works as a shuttle bus, transferring electrons from one molecule to another within cells to carry out all sorts of reactions and processes. With its molecular counterpart, NADH, this vital molecule participates in various metabolic reactions that generate our cell's energy. Without sufficient NAD+ levels, our cells wouldn't be able to generate any energy to survive and carry out their functions. Other functions of NAD+ include regulating our circadian rhythm, which controls our body's sleep/wake cycle.

FAQ
1. How to preserve peptides after receiving them?
Peptides in the form of lyophilized powder can be transported at room temperature by vacuum packaging, while polypeptides in the dissolved state need to be refrigerated at 2°C - 8°C. For long-term storage, peptides should be stored in the form of lyophilized powder stored at -20°C or -80°C in a sealed container with desiccant, which can avoid the degradation of peptides to the greatest extent.
