Related to lectin: lecithin


Any of various proteins or glycoproteins that bind to the sugar molecules of glycoproteins and glucolipids on the surfaces of cells and are found in most organisms, especially plants. They are used to stimulate lymphocyte proliferation and to agglutinate red blood cells.

[Latin lēctus, past participle of legere, to select; see select + -in.]


(Biochemistry) a type of protein possessing high affinity for a specific sugar; lectins are often highly toxic
[C20: from Latin lectus, past participle of legere to select + -in]


(ˈlɛk tɪn)

any of a group of proteins that bind to specific carbohydrates and act as an agglutinin.
[1954; < Latin lēct(us), past participle of legere to gather, select, read + -in1]

Noun1.lectin - any of several plant glycoproteins that act like specific antibodies but are not antibodies in that they are not evoked by an antigenic stimulus
glycoprotein - a conjugated protein having a carbohydrate component
