δ-aminolevulinic acid

δ-aminolevulinic acid
An acid formed by δ-aminolevulinate synthase from glycine and succinyl-coenzyme A; a precursor of porphobilinogen, hence an important intermediate in the biosynthesis of heme. ALA levels are elevated in cases of lead poisoning.
- δ-aminolevulinic acid synthase an enzyme that catalyzes the reaction of succinyl-CoA with glycine to form δ-aminolevulinic acid, coenzyme A, and CO2. The committed step in porphyrin biosynthesis.
