Final answer:
Multiple glutamic acid molecules must be hydrolyzed to absorb folate; both folate and vitamin C are water-soluble vitamins, with phosphorous being a stored element in the body. The correct option is C.
Step-by-step explanation:
Multiple glutamic acid molecules must be hydrolyzed off to absorb folate (vitamin B9). Folic acid, a form of folate used in dietary supplements and fortified foods, is associated with multiple glutamic acid residues. Once ingested, these extra glutamate residues are removed to convert it into the biologically active form of the vitamin.
In terms of vitamins stored in the body, phosphorous, which is an element rather than a vitamin, is stored in the body along with folic acid. However, it is worth mentioning that vitamin C and vitamin B9, such as folic acid, are both water-soluble vitamins and generally not stored in large amounts.
