Proteins and polysaccharides are polymers. these polymers are formed by dehydration synthesis. which statement correctly identifies a difference in the structure of proteins and polysaccharides? . select one: . a. only polysaccharides are composed of repeating units of a, t, c, g. b. only proteins are formed from amino acids joined together by peptide bonds. c. only polysaccharides can be folded and twisted into specific shapes. d. only proteins can grow into large molecules with thousands of subunits

The statement “only proteins are formed from amino acids joined together by peptide bonds” correctly identifies a difference in the structure of proteins and polysaccharides.

Polysaccharide is a carbohydrate (e.g., starch, cellulose, or glycogen) whose molecules consist of a number of sugar molecules bonded together.

Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.

The correct answer between all the choices given is the second choice or letter B. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
