Resistant starch I
Type 1 resistant starch (RS 1) includes starch present in
cells of plants with undamaged cell walls, occurring e.g. in
not completely ground cereal grain. It is unavailable to amylolytic
enzymes, since the gastrointestinal tract lacks
enzymes capable of degrading cellulose, hemicelluloses,
lignins, and other constituents of plant cell walls. Therefore,
such starch together with fragments of plant tissue passes
the small intestine in the intact form.
