Title: Amino Acid Polypeptide Q Post by: barry on Aug 19, 2010 I need help on the review question:
How many molecules of water are used up in the breakdown of a polypeptide 15 amino acids in length? B Title: Re: Amino Acid Polypeptide Q Post by: bio_man on Aug 19, 2010 (http://learn.ppdictionary.com/resources/bio_problem_3_diagram.gif) A polypeptide that has fifteen amino acids is held together by fourteen peptide bonds (count the lines in diagram). One molecule of water is consumed in the breaking of a peptide bond, therefore: 1 molecule of water x number of peptide bonds or: 1 x 14 = 14 water molecules are consumed to breakdown the polypeptide. |
