What's the difference between casein and legumin?

Casein


Definition:

  • (n.) A proteid substance present in both the animal and the vegetable kingdom. In the animal kingdom it is chiefly found in milk, and constitutes the main part of the curd separated by rennet; in the vegetable kingdom it is found more or less abundantly in the seeds of leguminous plants. Its reactions resemble those of alkali albumin.

Example Sentences:

  • (20) The results of our study show that the substitution of soy protein for casein can be of benefit in those patients who need a long-term hypocaloric diet.

Legumin


Definition:

  • (n.) An albuminous substance resembling casein, found as a characteristic ingredient of the seeds of leguminous and grain-bearing plants.

Example Sentences:

  • (1) Legumin was detected only in the seed of tobacco where the primary translation products were processed in a manner analogous to that which occurs in pea.
