Video transcript

Hi everyone here, we have a question telling us in an amino acid identify the bond formed by the side chain with the alpha carbon. A ionic bond. An ionic bond is formed between a metal and a nonmetal, so that is incorrect. Be a covalin bond. The side chain forms a covalin bond with the alpha carbon, so B is correct. See hydrogen bonds, hydrogen bonds take place between hydrogen and hydrogen atoms, so C. Is incorrect and D metallic bonds, metallic bonds happen between metallic substances, so D. Is incorrect. So our correct answer here is be Covalin bond. Thank you for watching. Bye.

Make a concept map (see BioSkills 12) that relates the four levels of protein structure and shows how they can contribute to the formation of hemoglobin. Your map should include the following boxed terms: Primary structure, Secondary structure, Tertiary structure, Quaternary structure, Amino acid sequence, R-groups, αα-helices, and ββ-pleated sheets.
