Micelles and Biological Membrane

Micelles are the type of lipid molecules that organize themselves in spherical shape in aqueous solutions. The production of the micelle is a reply to the amphipathic behavior of fatty acids. It means that they consist of both hydrophobic regions and hydrophilic regions. In micelles, polar head groups (hydrophilic groups) produce an outer layer associated with water whereas nonpolar tails (hydrophobic groups) are organized in the interior.

Stearic Acid (C18H36O2) is a typical fatty acid, a molecule with a long hydrocarbon chain and an organic acid group (COOH) at the end. It is used to make cosmetics, ointments, soaps, and candles and is found in animal tissue as part of many saturated fats. In fact, when you eat meat, chances are that you are ingesting some fats that contain stearic acid. Write a balanced equation for the complete combustion of stearic acid. Calculate its heat of combustion (ΔHf°(stearic acid) = -948 kJ/mol) Calculate the heat (q) in Joules when 1.00g of stearic acid is burned completely Show work please!

How many grams of oxygen do you need to burn 1 lb (454 g) of fat? Enter only a numerical answer, do not enter units. Note: for the molar mass of fat, use the chemical formula of an average triglyceride C55H10406 To calculate the mass of oxygen you MUST USE STOICHIOMETRY (convert mass of fat into moles, then mol of fat into mol of 02, then mol of O₂ into mass of O₂); do not use a simple proportion derived by the approximate data in the video.
