question 24
which of the following is true of sulfur?

the deficiency causes gastrointestinal distress.

the recommended intake is 300 mg per day.

it is a major mineral.

it is incorporated into lipid structures in the body.

Explanation:

• For the option "The deficiency causes gastrointestinal distress": Sulfur deficiency is not typically associated with gastrointestinal distress. Deficiencies of some other nutrients (like certain B vitamins, etc.) can cause GI issues, but not sulfur.
• For "The recommended intake is 300 mg per day": There is no established Recommended Dietary Allowance (RDA) or a set recommended intake of 300 mg per day for sulfur as the body can get sufficient sulfur from protein - containing foods (since sulfur is a component of some amino acids like cysteine and methionine), and the body's needs are usually met through normal protein intake.
• For "It is a major mineral": Major minerals are those required in relatively large amounts (more than 100 mg per day) by the body. Sulfur is considered a major mineral as it is an essential component of many biological molecules (like proteins, some vitamins) and is needed in significant quantities for various physiological processes.
• For "It is incorporated into lipid structures in the body": Sulfur is mainly incorporated into proteins (due to its presence in amino acids) and some vitamins (like biotin), not into lipid structures. Lipids are mainly composed of carbon, hydrogen, and oxygen (with some having phosphorus, like phospholipids), but not sulfur.

Answer:

It is a major mineral.
