ALT is an enzyme that transfers an amino group from the amino acid alanine to a ketoacid acceptor (oxaloacetate). The enzyme was formerly called serum glutamic pyruvic transaminase (SGPT) after the products formed by this reaction. Although ALT is present in other tissues besides liver, its concentration in liver is far greater than any other tissue, and blood levels in nonhepatic conditions rarely produce levels of a magnitude seen in liver disease. The enzyme is very sensitive to necrotic or inflammatory liver injury.elevated ALTis seen in Jaundice,Diabetes and other liver diseases
