Concept explainers
Interpretation:
The structure of folic acid and its role as a carrier for one carbon group are to be represented.
Concept introduction:
Folic acid is an organic compound commonly known as a form of vitamin. Folate is a vitamin B. It occurs naturally in foods, such as citrus fruits, green vegetables, beans, whereas folic acid is synthetic folate, usually incorporated to fortified foods. Certain biochemical reactions are known as one-carbon
The enzymes and coenzymes are involved in amino acid/

Comment on the validity of this remark.arrow_forwardREFLECT AND APPLY Outline the methods you would use to pro- duce human growth hormone (a substance used in the treatment of dwarfism) in bacteria.arrow_forward
- REFLECT AND APPLY In 1828, Wohler was the first person to synthesize an organic compound (urea, from ammonium cyanate). How did this contribute, ultimately, to biochemistry?arrow_forwardREFLECT AND APPLY Suggest a reason why the same protein system moves both sodium and potassium ions into and out of the cell.arrow_forwardREFLECT AND APPLY You are purifying a protein for the first time. You have solubilized it with homogenization in a blender followed by differential centrifugation. You wish to try ammonium sulfate precipitation as the next step. Knowing nothing beforehand about the amount of ammonium sulfate to add, design an experiment to find the proper concentration (% saturation) of ammonium sulfate to use.arrow_forward
