Question

Amino acids are
A) joined together by peptide bonds.
B) the building blocks of protein.
C) characterized as essential and nonessential.
D) all of the above.

Accepted Answer

Amino acids are joined together by peptide bonds to form proteins, and they are considered the building blocks of protein. They are also characterized as essential (those that cannot be synthesized by the body and must be obtained through the diet) and nonessential (those that the body can synthesize on its own). Therefore, all of the above statements are true, making D the correct answer.
