title: Ghrelin gets its GOAT.
abstract: Ghrelin, a powerful appetite-stimulating hormone secreted by the stomach, is modified by an octanyl side chain on its third amino acid, a serine, which is essential for its activity. A recent study (Yang et al., 2008) reports identification of the enzyme catalyzing the addition of this octanyl, GOAT.
