Introduction:

Despite the negative attention they often receive, fats (and other lipid molecules) play an extremely important role in the biochemical processes in our bodies. For this task, you will consider some of the biochemical roles of lipids (especially fatty acids) and demonstrate how a complete lack of fat in the diet would affect these biochemical roles and human health in general.

You should compile your work for this task in a single document that includes diagrams, text explanations, and references. If a requirement asks for an explanation, you should provide a written response in a narrative style (i.e., complete sentences rather than bullet points).

Scenario:

You have been asked to help dietitians in a local community health center to better understand the importance of fat in the diet and particularly how no-fat diets affect the biochemical processes of the body.

Requirements:

A. Explain how lipids, in the form of triglycerides, are broken down to produce ATP, including each of the following:
● the pathways involved in the breakdown
● the substrate(s) and end product(s) of the pathways

B. Explain two differences between saturated and unsaturated fatty acids (not fats).
1. Create one original 3-D model to demonstrate the chemical structure of a saturated fatty acid.
2. Create one original 3-D model to demonstrate the chemical structure of an unsaturated fatty acid.

C. Create an original diagram, with clear labels, to demonstrate the fluid mosaic structure of cell membranes.

Note: The inclusion of the following components aids in demonstrating the fluid mosaic structure: phospholipids, hydrophilic portion, hydrophobic portion, and membrane protein(s).

D. Explain how no-fat diets can affect the body (e.g., nutrient absorption, essential fatty acids), including each of the following:
● the molecule, or class of molecules affected
● how the absence of fat influences the availability of the molecule, or class of molecules
● the consequence(s), at the biochemical level (i.e., not simply physiological changes), of the change in availability

E. When you use sources, include all in-text citations and references in APA format.
