adhesion molecules definition
4 an attraction or repulsion between the molecules of unlike substances in contact: distinguished from cohesion. 5 (Pathol) abnormal union of structures or parts. (C17: from Latin adhaesion-a sticking. See adhere). Adhesion is the preferred term when talking about sticking or holding fast in a physical sense. Adherence is preferred when talking about attachment to a political party, cause, etc. English Collins Dictionary-English Definition & Thesaurus &nbsp. See also: adhesive, adhesiveness, Acheson, adhesively. Adhesion may refer to the joining of two different substances due to attractive forces that hold them. For instance, cohesion causes water to form drops and adhesion keeps the water drops on the surfaces of leaves and flowers in place. to the surface. Note 3: In surgery, adhesion is used when two tissues fuse unexpectedly. Adhesion is the tendency of dissimilar particles or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several types. Process of attachment of a substance to the surface of another substance. Note 1: Adhesion requires energy that can come from chemical and/or physical. linkages, the latter being reversible when enough energy is applied. They help cells stick to each other and to their surroundings. Their intracellular domain interacts with the cytoskeleton, while an extracellular domain interacts with the same or different types of cell adhesion molecules. Adhesion. Definition. noun. (physics, chemistry) The force of attraction between unlike molecules, or the attraction between the surfaces of contacting bodies. (cell biology) The binding of a cell to another cell, or a cell to a surface, via specific cell adhesion molecules. The extracellular domain has major repeats called extracellular cadherin domains (ECD). Sequences involved in Ca2+ binding between the ECDs are necessary for cell adhesion. The cytoplasmic domain has specific regions where catenin proteins bind. Chemical adhesion occurs when the surface atoms of two separate surfaces form ionic, covalent, or hydrogen bonds. The engineering principle behind chemical adhesion in this sense is fairly straightforward: if surface molecules can bond, then the surfaces will be bonded together by a network of these bonds. (Redirected from Adhesion molecules). Cell adhesion molecules (CAM s) are proteins located on the cell surface involved in binding with other cells or with the extracellular matrix (ECM) in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell Adhesion Molecules. Surface ligands, usually glycoproteins, that mediate cell-to-cell adhesion. Their functions include the assembly and interconnection of various vertebrate systems, as well as maintenance of tissue integration, wound healing, morphogenic movements, cellular migrations, and metastasis.
