Part of the molecules remaining is the R' group. does the dark the follow List the "R' group in Serine: Alanine: 10. In order for the following two amino acids to join and form a dipeptide, circle the -H of the amino group and -OH of the carboxyl group that are removed during dehydration reaction. OH CH2 H-N-C-C-OH CHy H-N-C-C-OH HHO Alanine H HO Serine 11. Redraw the two amino acids below to show the chemical bond that joins them together. bond. 12. The bond formed between these amino acids is called 60

Explanation / Answer

    8. a) The C which is attached to N on one side and C=O on the other side is the central carbon.

b)The N-H2 attached to the central carbon atom is the amino group.

c)The C=0-OH attached to the central carbon atom is the carboxyl group.

d)The H attached to the central carbon as shown below the central carbon is the hydrogen atom.

e)the R group of serine is -CH2OH and alanine R group is -CH3

10.) The OH group is removed from serine that is the carboxyl -OH gp and H is removed from alanine that is the H from the amino group(-NH2).

11.The bond that joins these two amino acids together is the -CONH bond formed between carboxyl gp of serine and amino gp of alanine.

12. The bond formed between amino acids is called peptide bond.

I m sorry,I couldnt upload an image due to server error but tried to explain in words.if you face problem,i will explain it again.
