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

LP70161-2   Alanine
Alanine is a non-essential amino acid that exists as two distinct enantiomers: L-alanine and D-alanine. Alanine is one of the primary amino acids (secondary to leucine) used for protein construction. It is produced from pyruvate, exists in high levels in plasma, and is involved in the metabolism of sugar and organic acids.[PubChem:Alanine] Alanine acts as a substrate for alanine aminotransferase (ALT), an enzyme commonly measured to determine liver health. Increased alanine levels are seen in patients with lactic acidosis, carbamoyl phosphate synthetase deficiency, histidinemia, hyperprolinemia, and ornithine transcarbamylase deficiency. In patients with a mitochondrial disease, elevated alanine levels are primarily seen during times of physiologic stress or regression.[PMID:18243024] Source: Regenstrief LOINC
