Question
A higher intake of this nutrient is required if the diet has a high amount of the antinutrient phytate, found in many seeds, as phytate strongly binds to this nutrient, preventing its absorption. For 10 points each:
[10e] Name this dietary mineral, the human body’s second most abundant trace metal after iron. This metal is used in a huge number of metalloproteins across all enzyme classes, including several featuring its namesake “fingers.”
ANSWER: zinc [or Zn]
[10m] Spinach and rhubarb have high levels of this antinutrient that inhibits calcium absorption, which can be reduced by cooking. This compound also increases the risk of kidney stones, which are made of its calcium salt.
ANSWER: oxalic acid [or oxalate]
[10h] Soybeans and many other legumes contain high concentrations of inhibitors that primarily block this enzyme, including Kunitz and Bowman–Birk types.
