Study Notes
Mineral Nutrients
- The human body requires macrominerals, a group of mineral nutrients, in relatively large amounts.
Sulfur and Its Forms
- Elemental sulfur is not directly utilized by the body; instead, it requires sulfur in its oxidized form, sulfate.
- Sulfate is the oxidized form of the mineral sulfur as it exists in foods and water.
Sulfur-Containing Amino Acids
- The amino acids methionine and cysteine, found in dietary proteins, provide the body with sulfate.
- These sulfur-containing amino acids help determine the structure and function of proteins.
Sulfur-Rich Body Parts
- Body parts containing some of the body’s more rigid proteins with a high sulfur content include hair, nails, and connective tissue.
