N-(O-phosphono-L-seryl)-L-aspartic acid, also known as phosphoaspartate or phosphoserine, is a phosphorylated derivative of the naturally occurring amino acid L-aspartic acid. In N-(O-phosphono-L-seryl)-L-aspartic acid, the hydroxyl group of the serine residue is phosphorylated, forming a phosphoester bond. This molecule plays a crucial role in various biological processes, including energy transfer and metabolic regulation. It is a key intermediate in the biosynthesis of L-arginine and L-lysine, two essential amino acids required for protein synthesis. Additionally, phosphoaspartate is involved in the Calvin cycle, a series of biochemical reactions that occur in the chloroplasts of plants during photosynthesis, where it helps in the fixation of carbon dioxide. The molecule's unique structure and function make it an important component in understanding cellular metabolism and the development of pharmaceuticals targeting metabolic pathways.
The CAS Registry Mumber 1492-20-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,9 and 2 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1492-20: (6*1)+(5*4)+(4*9)+(3*2)+(2*2)+(1*0)=72 72 % 10 = 2 So 1492-20-2 is a valid CAS Registry Number.
