Question

Calculate the RER for metabolizing the following molecules. Identify what they are likely to be (just at the level of carbohydrate, fat, and protein) and explain how you know that. ( you can ignore nitrogens, sulphurs, and sodiums and just balance carbons, hydrogens, and oxygens to their closest approximations in proteins). please show calculatoin.

C6H12O6 (glucose)

C18H30O2 (linoleic acid)

C16H32O2 (palmitic acid)

C29H50O21 (esamyl)

C12H22O11 (maltose)

C47H48N3O7S2Na (casein)

C123H193N35O37 (serum albumin)

C774H1224N210O222S5 (myoglobin)

C2H4O2 (acetic acid)

C14H26O11 (1,4---Glucan)

CH4N2O (urea)

Explanation / Answer

Glucose: Carbohydrate: C6H12O6 + 6O2 ------> 6CO2 + 6H2O
RER = 6/6 = 1

Linoleic acid: Lipid: C18H30O2 +24.5O2 -------> 18CO2 + 15H2O
RER = 15/24.5 = 0.612

Palmitic acid: Lipid: C16H32O2 + 23O2 -----> 16CO2 + 16H2O
RER = 16/23 = 0.696

Esamyl: Carbohydrate (Starch acetate): C29H50O21 + 31O2 -----> 29CO2 + 25H2O
RER = 29/31 = 0.935

Maltose: Carbohydrate: C12H22O11 + 12O2 ----------> 12CO2 + 11H2O
RER = 12/12 = 1
