Which best describes the structure of the molecules that make up proteins?

Proteins are made up of monomer units connected together. These units are called amino acids. Each amino acid has a carbonyl group and an amine group. These two groups will link when the amino acids are added. Also, an amino acid has a specific R group that characterizes which type of amino acid it is.

Hope this helps.

structure is maintained and sustained by:

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape

hope this .
