Identify and explain how certain water-soluble vitamins regulate proteins through post-translational modifications (altering the function of an existing protein by forming a covalent bond without changing its abundance). Explain how vitamin C interacts with fat metabolism. For carbohydrates (glycolysis/TCA), identify and discuss how vitamins are involved in procuring energy. For lipids (lipolysis/β-oxidation), identify and discuss how vitamins are involved in procuring energy.

What are post-translational protein modifications? How do they affect protein structures and functions? How can they be measured (name at least two ways)? Why should we care about them (hint: there are likely a few reasons; tell me about all of them)?

Briefly discuss two mechanisms of post-translation modification of protein synthesis.

Describe the different levels at which metabolism can be regulated (transcriptional, translational, post translational).
