Final answer:
The mineral provided by some proteins that is not found in either carbohydrates or lipids is sulfur. Sulfur is essential for the synthesis of proteins and is present in amino acids like cysteine and methionine.
Step-by-step explanation:
The mineral that some proteins provide that is not found in either carbohydrates or lipids is sulfur. Unlike carbohydrates and lipids, certain amino acids like cysteine and methionine contain sulfur, which is an essential element for the synthesis of proteins. Proteins play a critical role in various biological functions, including acting as enzymes, structural components, and signaling molecules, and sulfur is a vital part of their structure.
