Phaseolus vulgaris : Pinto bean
Pinto III

Molecular structure of
Pinto bean:Pinto III

Phaseolus vulgaris

Lecster ID:513 Edit Entry
Source Organism:Pinto bean
Species:Phaseolus vulgaris
Common Nomenclature:Pinto III
Index Nomenclature:LECa.Pha.Vul.xx.Xxxx
Characterization Notes:For characterization of Pinto III, see: Lect. Biol. Biochem. Clin. Biochem. 1982 (2) 743
Biological Activity:agglutinates group A erythrocytes at a titer of 1:256; group B erythrocytes at a titer of 1:256; group B erythrocytes at a titer of 1:256; by crude lectin preparation (16mg/ml). See: Int J Cancer 1970;6:283 Antinutritional factors of anasazi bean were compared to traditional pinto bean (Phaseolus vulgaris L. ). Anasazi beans contained less (p<0.001) soluble and bound condensed tannins compared to pinto beans. No differences (p>0.05) in stachyose and raffinose content were found between the two bean types; verbascose was not detected at all. Significant (p<0.05) differences in lectin content were observed between anasazi and pinto bean. The lectins of anasazi beans were classified as non toxic and those of the pinto beans as toxic types. No differences (p>0.05) in inhibitor activity against human and bovine trypsin and chymotrypsin were found between the two bean types. See: Plant Foods Hum Nutr 1997;51(2):85-98
