Apiaceae Apiaceae Apiaceae or Umbelliferae is a family of mostly aromatic flowering plants named after the type genus "Apium" and commonly known as the celery, carrot or parsley family, or simply as umbellifers. It is the 16th-largest family of flowering plants, with more than 3,700 species in 434 genera including such well-known and economically important plants such as ajwain, angelica, anise, asafoetida, caraway, carrot, celery, chervil, coriander, cumin, dill, fennel, hemlock, lovage, cow parsley, parsley, parsnip, sea holly, and silphium (a plant whose identity is unclear and which may be extinct). The Apiaceae family includes a significant number of phototoxic species
Cytochrome p450 family 19 subfamily a member 1 Cytochrome p450 family 19 subfamily a member 1 Cytochrome P450 family 19 subfamily A member 1 is a protein that in humans is encoded by the CYP19A1 gene. This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum and catalyzes the last steps of estrogen biosynthesis. Mutations in this gene can result in either increased or decreased aromatase activity; the associated phenotypes suggest that estrogen functions both as a
