APPLICATIONS
Peptides are the members of the compounds composed of two or more amino acids joined by the linking between one amino acid residue and the carboxyl group of the next amino acid by hydrolysis into linear, branched or cyclical structures. The link is an amide bond, and is sometimes referred to as a peptide bond. Peptides are playing a promising role in the molecular biology and in the creating medicines. Peptides are used in the study of protein structure and function, antibodies for the inhibition of cancer, for the study of protein structure and function research. Peptides are also used as instrumental in mass spectrometry. Biological activities of peptide are applicable in the fields of nutrition, medicine, and cosmetics.
  • Dipeptide: a molecule consisting of two amino acids
  • Tripeptide a molecule consisting of three amino acids
  • Octapeptide: a molecule consisting of eight amino acids
  • Oligopeptide: a polypeptide composed of approximately 2-12 amino acids length (or 3 to 40 component amino acids)
  • Polypeptide: a single molecule composed of approximately 13 or more amino acids.
  • Protein: a linear polypeptides that are normally synthesized on ribosomes.

Aspartame (or Aspartylphenylalanine) is the methyl ester of the dipeptide aspartyl phenylalanine. Chemically, it is Succinamic acid, 3-amino-N-(alpha- carboxyphenethyl)-, N-methyl ester, stereoisomer.  Aspartame is prepared by components of amino acids, aspartic acid and phenylalanine, with a small amount of methanol. It's marketed names are NutraSweet, Equal, Egal, or Canderal. Aspartame is a low-calorie sweetener used to sweeten a variety of foods and beverages, and as a tabletop sweetener. Aspartame is about 150-200 times as sweet as sucrose, tastes good, enhances flavors, saves calories and does not contribute to tooth decay. it is now the most popular sweetening ingredient in diet soft drinks. Aspartame trends to separate components when heated or over long periods, resulting in a loss of sweetness.
