the second compartment of the stomach of a ruminant any fine network (especially one in the body composed of cells or blood vessels) a small constellation in the southern hemisphere near Dorado and Hydrus
(Biyoloji) (A part of) endoplasmic reticulum that is tubular in form (rather than sheet-like) and lacks ribosomes. Its functions include lipid synthesis, carbohydrate metabolism, calcium concentration, drug detoxification, and attachment of receptors on cell membrane proteins
A membrane network within the cytoplasm of cells involved in the synthesis, modification, and transport of cellular materials. Membrane system within the cytoplasm of a eukaryotic cell (see eukaryote), important in the synthesis of proteins and lipids. The ER usually makes up more than half the membrane of the cell and is continuous with the outer membrane of the nuclear envelope (see nucleus). There are two distinct regions of ER: the rough ER, or RER (so called because of the protein-synthesizing ribosomes attached to it), and the smooth ER (SER), which is not associated with ribosomes and is involved in the synthesis of lipids and the detoxification of some toxic chemicals
