legumin (plural legumins)

  1. (biochemistry, organic chemistry) Any of a group of globulins, resembling casein, found mostly in legumes and grains.

      By evaporation, a substance of a gummy appearance, susceptible of redissolving in water, is obtained, and which possesses the composition of legumin, as is shown by the following numbers:—

      The legumin group includes edestin, glycinin, legumin from Vicia faba, arachin, and cocosin.

      The 11S proteins of pea and soybean, the legumins and glycinins, have been extensively studied.

      Contrary to the behaviour of legumin, complex formation with chitosan either decreases or does not affect both the enthalpy and entropy of legumin-T denaturation (Table 3).

Usage notes[edit]

Early investigators, including Justus von Liebig, considered it identical to mammalian casein and referred to it as vegetable casein.
