Ac-RYYRIK-NH2

Ac-RYYRIK-NH2 is a synthetic peptide that has been studied for its potential biological activities, particularly in the context of neuropeptide research. This peptide is an acetylated hexapeptide with the sequence Ac-Arg-Tyr-Tyr-Arg-Ile-Lys-NH2. It is of interest due to its structural similarity to certain endogenous peptides and its potential role in modulating physiological processes.

Structure and Composition

Ac-RYYRIK-NH2 is composed of six amino acids:

• Acetylated N-terminus (Ac-)
• Arginine (Arg, R)
• Tyrosine (Tyr, Y)
• Tyrosine (Tyr, Y)
• Arginine (Arg, R)
• Isoleucine (Ile, I)
• Lysine (Lys, K)
• Amidated C-terminus (-NH2)

The acetylation at the N-terminus and amidation at the C-terminus are modifications that can influence the peptide's stability and activity.
