N-acetylhomocysteine (NAHC) is a naturally occurring compound derived from homocysteine, an amino acid produced during the metabolism of methionine. It is formed when homocysteine is acetylated, a process that involves the addition of an acetyl group. NAHC plays a role in the regulation of homocysteine levels in the body, which is important for maintaining cardiovascular health, as elevated homocysteine levels are associated with an increased risk of heart disease. Additionally, NAHC has been studied for its potential therapeutic applications, including its ability to protect cells from oxidative stress and its role in the synthesis of certain neurotransmitters. However, it is important to note that while NAHC is a byproduct of homocysteine metabolism, it is not a direct precursor to cysteine, which is another important amino acid in the body.
The CAS Registry Mumber 7378-21-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,7 and 8 respectively; the second part has 2 digits, 2 and 1 respectively. Calculate Digit Verification of CAS Registry Number 7378-21: (6*7)+(5*3)+(4*7)+(3*8)+(2*2)+(1*1)=114 114 % 10 = 4 So 7378-21-4 is a valid CAS Registry Number.
