Question

what is the purpose of the r group in an amino acid monomer? shape and function determine type of fatty acid there is no function determines digestion rate

Explanation:

The R - group (side chain) in an amino acid monomer is unique to each amino acid. It can be non - polar (hydrophobic), polar (hydrophilic), acidic, or basic. These properties of the R - group influence the overall shape of proteins (through interactions like hydrophobic interactions, hydrogen bonds, ionic bonds etc. during protein folding) and also determine the function of the protein. For example, in enzymes (which are proteins), the R - groups of amino acids in the active site are crucial for substrate binding and catalysis.

Amino acids are not related to fatty acids (fatty acids are components of lipids). And the R - group definitely has a function. Also, the digestion rate of proteins is more related to factors like the overall structure of the protein, presence of proteases etc. rather than just the R - group of amino acids in a simple monomeric sense.

Answer:

shape and function
