|Section2= |Section7= }} Biliverdin is a green tetrapyrrolic bile pigment, and is a product of heme catabolism.〔Boron W, Boulpaep E. Medical Physiology: a cellular and molecular approach, 2005. 984-986. Elsevier Saunders, United States. ISBN 1-4160-2328-3〕〔Mosqueda L, Burnight K, Liao S (2005). "The Life Cycle of Bruises in Older Adults". Journal of the American Geriatrics Society. 53(8):1339-1343. 〕 It is the pigment responsible for a greenish color sometimes seen in bruises.〔 == Metabolism == Biliverdin results from the breakdown of the heme moiety of hemoglobin in erythrocytes. Macrophages break down senescent erythrocytes and break the heme down into biliverdin, which normally rapidly reduces to free bilirubin.〔 Biliverdin is seen briefly in some bruises as a green color. In bruises, its breakdown into bilirubin leads to a yellowish color.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Biliverdin」の詳細全文を読む スポンサード リンク
