Question

question 19 1 pts proteins are polymers of glucose. fats. nucleotides. amino acids. question 20 1 pts a saturated fatty acid is one in which all available bonds of its polypeptide chain are filled. all available bonds of its hydrocarbon chain are filled. one or more double bonds in its hydrocarbon chain are saturated with hydrogen atoms one or more double bonds in its polypeptide chain are saturated with hydrogen atoms.

Explanation:

Proteins are polymers made up of amino - acid monomers linked by peptide bonds. A saturated fatty acid has a hydrocarbon chain in which all available bonds are filled with hydrogen atoms (no double bonds), making it 'saturated' with hydrogen.

Answer:

Question 19: amino acids
Question 20: all available bonds of its hydrocarbon chain are filled
