Proteins are composed of monosaccharides linked by glycosidic bonds.
B
Proteins are composed of amino acids linked by peptide bonds.

검증된 단계별 안내1
Understand that proteins are one of the four major types of macromolecules in biology, alongside carbohydrates, nucleic acids, and lipids.
Recall that proteins are polymers made up of monomers called amino acids.
Recognize that amino acids are linked together by peptide bonds, which are formed through a dehydration synthesis reaction between the amino group of one amino acid and the carboxyl group of another.
Eliminate the incorrect options: Monosaccharides linked by glycosidic bonds form carbohydrates, nucleotides linked by phosphodiester bonds form nucleic acids, and fatty acids linked by ester bonds form lipids.
Conclude that the correct statement is: Proteins are composed of amino acids linked by peptide bonds.
