Part Descriptions

LP15818-5   Proline
L-Proline is one of the twenty proteinogenic units used in the building blocks of proteins. The other nineteen units are all primary amino acids, but due to the cyclic binding of the three-carbon side chain to the nitrogen of the backbone, proline lacks a primary amine group (ˆ'NH2). The nitrogen in proline is referred to as a secondary amine. Proline is sometimes called an amino acid, although the IUPAC definition of an amine requires a carbon-nitrogen double bond.

LP15818-5   Proline
Proline is an amino acid that is the cyclized form of glutamic acid. The hydroxylation of proline increases the stability of collagen and is critical for maintaining connective tissue. Increased with iminoglycinuria,Type I and II hyperprolinemia, and lysinuric protein intolerance. Source: Regenstrief Institute

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.
