- Give the Essential amino acids with the carboxyl group, amino group, and the Radical/Side Chain in the proper positions. Show in RED ink the amide bonds in the polypeptide formed in the essential amino acids. Give the name of the polypeptide. Copy and complete the table below.arrow_forwardBriefly explain what a trans fat bonding arrangement isarrow_forwardWhich of these statements about hemoglobin is NOT true? A) it is a tetrameric globular protein b) it has a prosthetic group called heme c) it’s dominant motif is beta barrel d) its dominant motif is helix-turn-helix The reagent used to break disulfide bonds is: a) urea b) beta-mercaptoethanol c) guanidine hydrochloride d) phosphorus pentachloridearrow_forward
- Hemoglobin is a tetramer consisting of two a and two b chains. What level of protein structure is described in the above statement?arrow_forwardIdentify the TRANS BOND.arrow_forwardWrite a reaction for formation of the following nucleoside: Beta- D-ribofuranose with cytosine. a. What kind of bond is that? Which is the specific atom from cytosine involved?arrow_forward
- Consult Table 18.3 and draw alanine. Label the functional groups and give the three-letter abbreviation and the one-letter abbreviation. What group does the side chain fall into?arrow_forwardIf you heat a protein to break the intramolecular hydrogen bonds, will you maintain the a-helical or b-sheet structure?arrow_forwardat room temperature, amino acids are solids with relatively high decomposition points. explain whyarrow_forward
- Match the given statement to the corresponding type of ribonucleic acid.arrow_forwardMost protein dissolve in neutral salt solution, is that true? Provide reasoningarrow_forwardif i have protein with 110kda and its cysteine joining with disulfide bond . and one cysteine acids per 100 amino when i heated at 85c it lost activity but if i cool it the activity will restore the questions are : how many disulfide bonds in this protein with explanation? and what is molecular basis to restore activity?arrow_forward
