Inhibitory effect of 1. on some enzymes: The endogenous ATPase inhibitory protein isolated from the mitochondria of potato tuber needs Mg2+-ATP to inhibit F1-ATPase. The IC50 of the isolated yeast strain F 1 is 140μg (inhibitor) /mg(F 1). This inhibitor also has a strong ATPase inhibitory effect on isolated yeast F 1.

2. The average gastric emptying time of potato and rice is 7 1 min and 86 minutes respectively. Because the glycemic index is negatively correlated with gastric emptying time, rice is more suitable for diabetic patients than potatoes. Experiments in rats showed that solanine injection into potato could increase blood sugar, and blocking α -or β -adrenergic receptor could inhibit this effect. Potato can be used as a specific marker of thyroid tumor in rats in plant lectin test.

Extended data

toxicity

The stems and leaves of potato plants are poisonous, and even the potato itself is poisonous. If you look at potatoes carefully, you may find that some potatoes are slightly green, which is caused by the toxicity of glycoside alkaloids.

In the past, there were also cases of death due to potato poisoning. Although few, most of them are due to drinking potato leaves or eating green potatoes. The fatal incident is not sudden, and the parties are often weak at first and fall into a coma after eating.
