a tiny granule in the cytoplasm of a cell; it consists of ribosomes bound to fragments of the endoplasmic reticulum and mitochondria.
any of the vesicular fragments of endoplasmic reticulum formed after disruption of and centrifugation of cells.6
Irregular membranous structures in the cytoplasm containing various enzymes. In these structures some noncarcinogenic compounds are converted to carcinogens with the help of specific enzymes. These structures are also involved in the detoxification of drugs and other unwanted materials.
a tiny granule in the cytoplasm that is where protein synthesis takes place under the direction of mRNA
Refers to one of several membrane-containing structures within a cell; there isn't one structure which is the "microsome", as the term refers to a fraction found after centrifuging a cell sample.
A small closed vesicle created by mechanical disruption of the rough endoplasmic reticulum.
Artefactual spherical particle, not present in the living cell, derived from pieces of the endoplasmic reticulum present in homogenates of tissues or cells: microsomes sediment from such homogenates when centrifuged at 100 000 g and higher: the microsomal fraction obtained in this way is often used as a source of mono-oxygenase enzymes RT cytochrome P-420, cytochrome P-448, cytochrome P-450, endoplasmic reticulum, mono-oxygenase, phase 1 reactions
In cell biology, a microsome is a small vesicle that is derived from fragmented endoplasmic reticulum (ER) produced when tissues such as liver are mechanically broken (homogenized). Microsomes contain the cell's cytochrome P450 (CYP) enzymes, involved in oxidative metabolism.
