Question

Quizplus · Accepted Answer

While most proteins contain a range of amino acids, the relative amounts of each can vary widely depending on the specific protein's function and properties. Some proteins, for example, may contain high proportions of certain amino acids that are needed for specific molecular interactions or enzymatic activity, while others may have low levels of certain amino acids that are difficult to synthesize or that can cause structural issues if over-represented. Overall, the amino acid composition of a protein can play a key role in determining its properties and function.
