D Provide "quick energy' for cells.
C)
Proteins are made from chains of amino acids. The
amino acids are joined together by structures called
peptide bonds.
For this problem, draw all hydrogen atoms explicitly.
Part A
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 pH 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 hydrogen
atoms and charges.
can you help me with this question? the list at the bottom is for part a.

- You have been so enamored with lab during your time in Biol201 that you decide to do some biology research yourself over summer break. You discover that the single macromolecule shown below is found in Piggy's skin. 1. What type of macromolecule is shown? a. Name the level of organization of the overall structure. b. Name the secondary structure(s) visible. c. Name the bond holding together the monomers of this structure. d. What effect would a silent mutation have on the shape of this structure?arrow_forwardCan you help me to explain to me?arrow_forwardMacromolecules are very large molecules created by the polymerization of small units called monomers. Most of the macromolecules are present in everyday life, for instance in food. In the Introduction to Food Macromolecules simulation, you will help your friend determine a healthy diet and investigate the types of macromolecules found in food. By performing a series of biochemistry tests, you will know the content of various food items. * * What are the different forms (i.e., monomers, polymers) of carbohydrates, lipids, and proteins? * What macromolecules do each of the biochemical tests check for? * What would an abundance or deficiency of one of the macromolecules cause to the human body?arrow_forward

- You have discovered a new molecule in outer space. You have never seen this type of molecule before on Earth. You analyze the composition and discover that it is made of 28% carbon atoms, 24% oxygen atoms, and 48% hydrogen atoms. You immediately decide that it is not an alien protein or an alien nucleotide. Explain why you know that the molecule cannot be a protein or a nucleotide. Do you think that the molecule is an alien fatty acid or an alien carbohydrate? Explain your decision Will your molecule be hydrophilic or hydrophobic? Explain your answer considering polarity and electronegativityarrow_forwardYou put albumin, the protein responsible for lipid transport through the blood, in methane, a hydrophobic solution. Would you expect albumin to still be functional? Yes the protein would still be functional because its primary structure remains intact Yes the protein would still be functional because it is used to carry lipids No the protein would not be functional because the peptide bonds would be dehydrated No the protein would not be functional because covalent bonds weaken and disrupt secondary structure No the protein would not be functional because the tertiary structure would change to maximize hydrophobic interactionsarrow_forwardHow is a macromolecule formed? By the removal of water to form a hydrogen bond? Or is it the addition of water to form a glycosidic bond? However, it could also be the formation of water to form either a covalent OR ionic bond. Thanks ????arrow_forward
- A famous experiment used the chemicals found in the early atmosphere of the earth and added energy from electrical sparks to show that the beaker accumulated the building blocks of life (the monomers, such as amino acids). Is it also important to show that the early earth was able to polymerize these building blocks of life into chains of monomers (polymerization with chemical bonds between monomers)? Why?arrow_forwardThank you for your assistancearrow_forwardChemistry A homotetramer (lacking intermolecular covalent interactions) has a native molecular size of 60 kDa.
