Lectins from legume plants, such as PHA or concanavalin A, have been used widely as model systems to understand the molecular basis of how proteins recognize carbohydrates, because they are relatively easy to obtain and have a wide variety of sugar specificities.
As lectinas de legumes, como as fitohemaglutininas (PHA) ou a concanavalina A foron moi utilizadas como sistemas modelo para comprender as bases moleculares do recoñecemento de carbohidratos polas proteínas, porque son relativamente doadas de obter e teñen unha ampla variedade de especificidades de azucres.
