- 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.arrow_forwardThe three-dimensional structure of biomolecules is more conserved evolutionarily than is sequence.

- 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_forwardA mutation leads to a change in amino acid from valine, an amino acid with a nonpolar side chain, to aspartic acid, an amino acid with a polar, negatively-charged side chain. Do you think that the following levels of protein structure change? If so, how and why? If not, why not? Please frame your answer in terms of chemical bonds and interactions. (primary structure, secondary structure, tertiary structure, quartenary structure)arrow_forwardHow can I classified carbohydrates, protein, nucleic acid and lipids according to their structures?

- Hello, I need help with answering number 2 a, b, c, & d using the diagram below. Pls & thank you! 2. a) 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? 2. b) If nitrogenous bases (A, G, C, T or U) could polymerize to chains of nucleotides, could this eventually form the structure shown in the figure above? Would an RNA structure that can act as an enzyme, such as the one shown above, have been the result of chemical evolution with competition between replicating RNA molecules? Or was it likely the first RNA molecule that arose from a chain of nitrogenous bases could immediately act as an enzyme? 2. c) In addition…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_forwardAdd these terms to your concept map should include these concepts and details: - the main title should be macromolecules concept of biochemistry with the following major categories: Water, Carbohydrate, Proteins, Lipids→ include cell membranes, Nucleic Acids Your concept map should include these concepts and details: Structure (functional groups, shape); Monomer; building block molecules Linkage; Properties; Functions; Key terms from the Partial List of Key functional group polarity intermolecular forces of attraction hydrogen bond essential nutrient carbohydrate monosaccharide isomer glycosidic linkage monomer polymer disaccharide oligosaccharide polysaccharide intermolecular force of attraction hydrogen bond macronutrient essential amino acid amino acid side group/R-group peptide bond polypeptide receptor neurotransmitter hormone secondary structure tertiary structure quaternary…arrow_forward
