4. Lectin
   Lectin: A complex molecule that contains both protein and sugar. Lectins are made by both animals and plants and are able to bind to the outside of a cell and cause biochemical changes in it.

5. lectin
   Proteins obtained particularly from the seeds of leguminous plants, but also from many other plant and animal sources, that have binding sites for specific mono- or oligosaccharides. Named originally for the ability of some to selectively agglutinate human red blood cells of particular blood groups. Lectins such as concanavalin A and wheat germ agglutinin are widely used as analytical and preparative agents in the study of glycoproteins. See Table L1.

6. lectin
   <plant biology> Proteins obtained particularly from the seeds of leguminous plants, but also from many other plant and animal sources, that have binding sites for specific mono or oligosaccharides in cell walls or membranes. They thereby change the physiology of the membrane to cause agglutina...

12. Lectin
    `Lectins` are sugar-binding proteins (not to be confused with glycoproteins, which are proteins containing sugar chains or residues) that are highly specific for their sugar moieties. They play a role in biological recognition phenomena involving cells and proteins. For example, some viruses use lec...
