Answer questions 7-8 please ! Draw a picture of two amino acids coming together to make...
On paper draw a dipeptide, clearly showing the peptide bond joining the two amino acids together. If the two amino acids are valine and threonine, predict the overall charge of the dipeptide at pH 7. Do not forget to consider the amino (N-terminal) and carboxy (C-terminal) of the dipeptide, as well as the R groups. Select one: a. +2 b. -2 c. 0 d. -1 e. +1
7.Draw the basic structure of an amino acid dimer (two amino acids bound together); label an amine, carboxyl, side chainand peptide bond. 8.Define primary and tertiary protein structure. How does the tertiary structure depend on the primary structure?
HW Question: Draw the amino acids, lysine and valine joined by a peptide bond. Next, place a square around the peptide bond within the dipeptide molecule. Finally circle all the atoms which could interact with a water molecule.
Proteins are made from chains of amino acids. The amino acids are joined together by structures called peptide bonds. Draw the dipeptide that results when a peptide bond is formed between the two glycine molecules shown here. (Figure 1) Draw it as it would occur at the pHpH of most body fluids. Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. Include all...
Glutamine, tyrosine, leuonine, phenyalanine, histine, methalonine Draw a peptide bond between two of the amino acids above and name the dipeptide bond you have drawn
Draw a peptide of two or more different amino acids. Circle the R group of each amino acid. Put a box around each peptide bond. Identify each amino acid with the one-letter code.
