Biochemistry fill in the blanks question
CH H2 H Alan e NH OH Fill in the blanks with the appropriate number that would correctly complete each statement c 1n this peptide molecule there are a total of amino acids. In this peptide there are amino acids would be classified as polar, charged amino acids andamino Tr acids which would be classified as polar, uncharged. This peptide would have_ pK values associated with it. The version of this molecule shown above would most likely exist ata-Tyo pH between and . At a pH of 1 this molecule would have an overall charge of On this molecule there are bonding interactions and bonding interactions. There appear to be Nitrogen atoms which are likely to be making Hydrogen Hydrogen atoms which are likely to be making Hydrogen amino acid side chains which appear to have groups on them that were added post-translational (or what is the number of post-translationally modified amino acid side chains).Explanation / Answer
I am doing it sequentially.
--- 5 (If there are N peptide bonds in peptide chain then there are N+1 amino acids residue in that peptide chain. In this peptide there are 4 peptide bond so there are 5 amino acids).
--- 1 Here there is only right most amino acid which is polar and have charged carboxylic group (This is Histidine).
--- 1 Left most amino acid (Tyrosine) is polar but does not have any charge.
--- 4 One for R-group of Tyrosine (left most), one for added -OH group of Proline, One for R-group of Histidine (right most) and one for right most carboxylic acid
--- 10 to 14 As there are not any protonated group so the pH must be greater than all the pKa value
--- 3 As pH=1 is less than all the available pKa so all will be protonated but protonated form of carboxylic group have 0 charge that's why it have only 3 not 4.
--- 0 As there is no adjacent Oxygen which contain Hydrogen atom.
--- 4 All the Hydrogen atom of Nitrogen of peptide bonds will form H-bond with the Oxygen of the same peptide bond.
--- 2 One is the Phospate group which is added to the Threonine and other one is the Hydroxy group attached to ring of proline.
