Part Descriptions

LP15699-9   Leucine
Leucine, an essential amino acid isomeric with isoleucine, is the most common amino acid found in proteins. It is required for optimal growth in infancy and childhood and for nitrogen equilibrium in adults. It is also involved in maintaining muscles mass by equalizing synthesis and breakdown of proteins. The major food sources of leucine are whole grains, milk and milk products, eggs, meat, soy beans, and leafy vegetables. Leucine toxicity, as seen in decompensated Maple Syrup Urine Disease (MSUD), causes delirium and neurologic compromise, and can be life-threatening.

LP15699-9   Leucine
Leucine is an essential nonpolar hydrophobic amino acid with a nonpolar branched-chain R group. It is increased with Maple Syrup Urine Disease (MSUD). (Information from ARUP Laboratories 9/14/06) 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.
