Tyr-D-Met(O)-Gly-Phe-NH-NH2 is a peptide compound consisting of six amino acids: Tyrosine (Tyr), D-Methionine (D-Met), Methionine Sulfoxide (Met(O)), Glycine (Gly), Phenylalanine (Phe), and two terminal amino groups (NH-NH2). This sequence is known for its potential role in the body's response to stress and inflammation, as it is structurally similar to certain endogenous peptides. The presence of D-amino acids, such as D-Met, is noteworthy because they are less common in naturally occurring proteins and can confer unique properties to the peptide. The sulfoxide group in Met(O) adds an additional layer of complexity, potentially affecting the peptide's reactivity and biological activity. Overall, Tyr-D-Met(O)-Gly-Phe-NH-NH2 is a synthetic peptide with a specific sequence that may have implications in various biological processes, including those related to the immune system and stress response.
The CAS Registry Mumber 72732-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,3 and 2 respectively; the second part has 2 digits, 4 and 7 respectively. Calculate Digit Verification of CAS Registry Number 72732-47: (7*7)+(6*2)+(5*7)+(4*3)+(3*2)+(2*4)+(1*7)=129 129 % 10 = 9 So 72732-47-9 is a valid CAS Registry Number.
