Part Descriptions

LP15504-1 Citrulline
Citrulline is an alpha amino acid, produced from ornithine and carbamoyl phosphate during the urea cycle. Its name is derived from citrullus, the Latin word for watermelon, from which it was first isolated. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

LP70160-4 Phenylalanine
Phenylalanine is an essential alpha-amino acid. It exists in two forms, a D and an L form, which are enantiomers (mirror-image molecules) of each other. It has a benzyl side chain and its name comes from its chemical structures that consists of a phenyl group substituted for one of the hydrogens in the side chain of alanine. Because of its phenyl group, phenylalanine is an aromatic compound that at room temperature exists as a white, powdery solid. L -phenylalanine (LPA) is an electrically-neutral amino acid and its enantiomer, D -phenylalanine (DPA), can be synthesized artificially. L -phenylalanine can also be converted into L -tyrosine, another one of the twenty protein-forming amino acids. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
