After the peptide chain of collagen has been formed, many of the proline residues are hydroxylated on one of the ring carbon atoms. Why is this process important for the triple helix of collagen?
In principle, there are many different, chemically diverse ways in which small molecules can be linked to form polymers. For example, the small molecule ethene (CH2=CH2) is used commercially to make the plastic polyethylene (...–CH2–CH2– CH2–CH2–CH2–...). The individual subunits of the three major classes of biological macromolecules, however, are all linked by similar reaction mechanisms, i.e., by condensation reactions that eliminate water. Can you think of any benefits that this chemistry offers and why it might have been selected in evolution?
What structure(s) contain(s) ribose?

- Together, these monomers make up what type of polymer (macromolecule)? List at least three (broad) functions that these macromolecules can perform. What is an example protein that we’ve discussed that uses of these functions? Using R as the side chain, draw the basic structure of an amino acid.arrow_forwardGlycerolphospholipid head groups include coline, ethanolamine, glycerol and serine. Which of these groups can use hydrogen bonding or rather participate in in. And why?arrow_forwardHair is made of protein. The protein is a structural protein called α-keratin, which contains many disulfide (S-S) bridges formed from sulfhydryl functional groups found amongst amino acids radical groups. Based on how the protein folds, the radical groups have opportunities to generate multiple disulfide bridges. The greater the number of disulfide bridges, the more tightly the hair is coiled. Using your knowledge of proteins, write a brief paragraph theocratizing how sodium hydroxide is used in hair products to straighten hairarrow_forward
