L-α-Aspartyl-L-tyrosine

Description:

L-α-Aspartyl-L-tyrosine, also known as aspartame, is a dipeptide composed of the amino acids aspartic acid and tyrosine. It is characterized by its sweet taste, which is approximately 200 times sweeter than sucrose, making it a popular artificial sweetener in various food and beverage products. This compound is soluble in water and has a relatively low molecular weight, which contributes to its sweetening properties. L-α-Aspartyl-L-tyrosine is stable under acidic conditions but can degrade under high temperatures or alkaline conditions, which limits its use in certain cooking applications. Additionally, it is important to note that individuals with phenylketonuria (PKU), a genetic disorder, must avoid aspartame due to its phenylalanine content. The substance is generally recognized as safe (GRAS) by regulatory agencies when consumed within established daily intake limits. Its use in food products has been extensively studied, and it continues to be a subject of research regarding its long-term health effects.

Cholecystokinin Octapeptide (1-2) (desulfated)

CAS: 22840-03-5

Cholecystokinin octapeptide (1-2) (desulfated) H-Asp-Tyr-OH is a peptide that has been found to have hypotensive properties. It is an agonist of the CCK receptor and has been shown to be effective in lowering blood pressure. Cholecystokinin octapeptide (1-2) (desulfated) H-Asp-Tyr-OH stabilizes membranes, which may account for its ability to reduce the permeability of erythrocyte membranes. This peptide also interacts with histidine residues in striate muscle, which may account for its ability to relax smooth muscle. Cholecystokinin octapeptide (1-2) (desulfated) H-Asp-Tyr-OH is orally administered or can be hydrolyzed into amino acids in the gastrointestinal tract.
