Amino Acids

Amino acids are the precursor bulding blocks of proteins.  Each amino acid contains a central carbon, a hydrogen, a carboxyl group, an amino group, and a variable R group.  While there are over 500 amino acids in nature, 22 are by far the most important which are incorporated into proteins.  One of the most useful ways to classify the 22 canonical amino acids is based on the properties of the R group: Group I – Nonpolar Amino Acids (glycine, alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, and tryptophan), Group II – Polar, Uncharged Amino Acids (serine, cysteine, threonine, tyrosine, asparagine, and glutamine), Group III – Acidic Amino Acids (aspartic acid and glutamic acid), and Group IV – Basic Amino Acids (arginine, histidine, and lysine).

Amino acids are also precursors of a variety of complex nitrogen-containing molecules.  Prominent among these are the nitrogenous base components of nucleotides and the nucleic acids (DNA and RNA).  Several amino acids (or their derivatives) act as chemical messengers and neurotransmitters such as gamma-aminobutyric acid (derived from glutamic acid), serotonin and melatonin (derivatives of tryptophan), and histamine (derived from histidine).  Thyroxine (a derivative of tyrosine) and indole acetic acid (a tryptophan derivative found in plants) are two examples of hormones.

CASSIA, LLC has many years of experience in the production of metabolic intermediates. We are beginning new amino acid high efficiency enzymatic synthesis projects, offering milder reaction conditions, simple operation, high reaction specificity, few side reactions, and simple isolation and purification of reaction products. In the process of amino acid production, we can continually optimize our protocols to provide customers with the best production service. We are developing a range of synthetic routes for the production of amino acid analogs, enabling rapid and efficient synthesis of modified amino acids analogs and their derivatives. CASSIA, LLC has built a well-equipped lab and employs skilled researchers and partners that ensure we have the ability to provide high-quality results at an affordable price.

Applications:

  • Amino acids and precursors can be used as feedstock for the production of chiral molecules.
  • Isotope labeled amino acids and precursors can support analytical efforts and data analysis in proteomics and metabolomics.
  • Custom isotope amino acids and precursors can support cell culture media and in vitro protein expression.
