- The alpha-keratin of hair is rich in the amino acid cysteine. The location of these cysteines in the protein chain is genetically determined. As a result of the location of the cysteines in the protein, a person may have curly, wavy, or straight hair. How can the location of cysteines in a-keratin result in these different styles of hair?

In lab, you recorded a UV-Vis spectrum of a mixture of proteins. What best explains why two major peaks were observed in your spectrum between 240 and 480 nm? i. Amino acids absorb light at two wavelengths depending on their identity. The sample was impure. All proteins absorb light at 280 due to the presence of aromatic amino acids and red proteins absorb light near 400 nm. The buffer absorbs light in the visible region and the proteins absorb light in the UV region of the spectrum. None of the above. ii. iii. iv. V. d. In lab, you ran an SDS-PAGE gel. What best explains the importance of adding SDS and heating your samples? i. SDS is a dye used for visualization and heat is used to dissolve the SDS in solution. iii. iv. SDS coats the protein with negative charge and heat aids in the unfolding of the proteins. SDS and heat both help stabilize the proteins during gel electrophoresis.

SDS‑PAGE is a protein used as a loading control to confirm the same amount of sample was added to each well. SDS‑PAGE is a technique that separates proteins in a mixture based on their size (molecular weight). PAGE is a blocking solution that prevents non‑specific antibody binding, giving all proteins a similar charge‑to‑mass ratio. SDS is a detergent in the polyacrylamide gel that gives all proteins a similar charge‑to‑mass ratio.arrow_forward
