lipids

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:

Design either a multimedia presentation (e.g., PowerPoint, Keynote, Google Presentation) (suggested length 5–10 slides) or a brief report (e.g., Microsoft Word) (suggested length 2–3 pages) on the role of fat and why it is important in the diet, in which you do the following:

Note: Please save submission documents as *.ppt, *.pptx (PowerPoint), *.key (Keynote) *.doc, *.docx (Word) or *.pdf (Portable Document Format) files. If you are using Google Presentations or Documents, you must save the file in *.pdf format and upload the *.pdf file.

A. Explain how energy is stored as fat, including identification of the storage molecule and tissue.
1. Describe how the storage molecule is broken down and used to produce ATP.

B. Compare three features of saturated and unsaturated fatty acids.
1. Create two original 3-D models to demonstrate the chemical structure of a saturated and an unsaturated fatty acid.

Note: Take a picture of your completed 3-D models as evidence that you created them. You can include the picture as part of your presentation or report, or you can upload it in Taskstream as a separate attachment.

2. Explain three roles of fatty acids in the body.

C. Provide a diagram to demonstrate the fluid mosaic structure of cell membranes.
1. Label the following components in your diagram:
• phospholipid
• hydrophilic portion
• hydrophobic portion
• membrane protein(s)

D. Explain two specific examples of how no-fat diets can affect the body (i.e., nutrient absorption, essential fatty acids, etc.) at the biochemical level.
