Saturated/Unsaturated Fatty Acid Structures
Understanding the chemical structure for saturated and unsaturated (cis and trans) fatty acids. A “fat molecule” is also called a “triglyceride” or “triacylglyceride.” Fatty acids have a polar carboxylic acid “head” and a non-polar hydrocarbon “tail.” Overall, a molecule with a large hydrocarbon chain is more soluble in fats/oils/hydrocarbons (ie. nonpolar solvents). In general, we use the phrase “like dissolves like” to predict the solubility of a compound in a polar or non-polar solvent. A molecule with a very short hydrocarbon chain (vinegar/acetic acid) is more soluble in water; the polar carboxylic acid functional group “wins”. The hypothetical fat molecule that I showed is called a “triglyceride” because the glycerol is esterified with 3 fatty acids.
Fish Oil and Omega 3 Fatty Acids
Dear All, This is my response to Dr. Barry Sear’s Fish Oil, omega-3 fatty acid video. Thanks for watching! For more information on fish oil and what fish to eat, please check out my blog: bostonmedicalstudent.wordpress.com Here is more info: 1) For a general overview of omega 3 fatty acids, this is a good summary: lpi.oregonstate.edu This Newsweek article is also a good summary (it’s a shorter article): www.msnbc.msn.com 2) For my video, I relied primarily on: Lee et al., Current Clinical Applications of Omega 6 and Omega 3 Fatty Acids. Nutrition in Clinical Practice 21:323-341. This is the review article written by the faculty and doctors at Harvard Medical School. Other random, but interesting facts: “There have been a number of clinical trials assessing the benefits of dietary supplementation with fish oils in several inflammatory and autoimmune diseases in humans, including rheumatoid arthritis, Crohn’s disease, ulcerative colitis, psoriasis, lupus erythematosus, multiple sclerosis and migraine headaches. Many of the placebo-controlled trials of fish oil in chronic inflammatory diseases reveal significant benefit, including decreased disease activity and a lowered use of anti-inflammatory drugs.” From: www.jacn.org “As such, at the moment, there is some expectations of benefits and a reasonable certainty of no harm (from omega-3′s). Dose requirements for the prevention of sudden death (in the order of 0.85 g/day EPA plus DHA in the GISSI-Prevenzione trial [98]) are …
Coronary Heart Disease Video
Coronary heart disease is the leading cause of both men and women in the US. Coronary heart disease kills almost 700000 people each year. Coronary heart disease occurs when arteries that supply the heart become narrowed and may cause a heart attack. Dr. Dahlman’s video describes how coronary heart disease can be reversed or prevented by a healthier diet.
