Question

Amino acid side groupsa) help determine the structure of the protein and its function.b) can be found throughout an individual's DNAc) are the parts that are linked together to form long chainsd) will be removed when amino acids are linked togethere) are the same for every amino acid, to allow efficient packing.

Answer 1

Amino acids have a basic structure of an a- carbon with four groups attached: hydrogen, an a-carboxyl group, an a-amine group, and an R-group, also known as a side chain (C and D are false).

The side chain or R group is what makes every amino acid different and gives them unique properties (E is false). Given their R groups, amino acids can be classified as non-polar and neutral, polar and neutral, acidic and polar, or basic and polar.

The properties of each amino acid and their interaction is what determines the structure of the protein and its function (A is correct)
