| Leucine Crystals Leucine crystals indicate a problem with the metabolism of the amino acid leucine. These crystals are round to oval with radiating bands going from a center point out to the periphery, often referred to as a "wagon wheel." These crystals are soluble in hot alcohol and alkali. | View Page |
| Tyrosine Crystals Tyrosine crystals appear as fine silky needles arranged in sheaves or bundles in acid urine. They are rarely present and may appear together with leucine crystals in liver disease. Do not confuse tyrosine with crystals caused by x-ray dye. X-ray dyes will cause the urine specific gravity to be greatly increased (1.040), Tyrosine crystals are soluble in alkali or dilute mineral acid. | View Page |
