A hepatocyte is a cell of the main parenchymal tissue of the liver. Hepatocytes make up 70-85% of the liver's mass. These cells are involved in: * Protein synthesis * Protein storage * Transformation of carbohydrates * Synthesis of cholesterol, bile salts and phospholipids * Detoxification, modification, and excretion of exogenous and endogenous substances * Initiation of formation and secretion of bile ==Structure== The typical hepatocyte is cubical with sides of 20-30 µm, (in comparison, a human hair has a diameter of 17 to 180 µm).〔Ley, Brian (1999). "Diameter of a Human Hair". Archived from the original on 2010-06-28. Retrieved 2010-06-28.〕 The typical volume of a hepatocyte is 3.4 x 10−9 cm3.〔Lodish, H., Berk, A., Zipursky, S. L., Matsudaira, P., Baltimore, D., Darnell, J. E. Molecular Cell Biology (Fifth Edition). W. H. Freeman and Company. New York, 2000, pp 10.〕 Smooth endoplasmic reticulum is abundant in hepatocytes, whereas most cells in the body have only small amounts. 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「Hepatocyte」の詳細全文を読む スポンサード リンク
