Examples of omega-6 in the following topics:

  • Lipids: Sources, Uses in the Body, and Dietary Requirements

    • Humans and other mammals require fatty acids such as linoleic acid (an omega-6 fatty acid) and alpha-linolenic acid (an omega-3 fatty acid), because they cannot be synthesized from simple precursors in the diet.
    • Both omega-6 and omega-3 are 18-carbon polyunsaturated fatty acids that differ in the number and position of their double bonds.
    • Fish oils are especially rich in the longer-chain omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) .
    • Numerous studies have shown that the consumption of omega-3 fatty acids has positive benefits in terms of infant development, cancer, cardiovascular disease, and mental illnesses such as depression, attention-deficit hyperactivity disorder, and dementia.
    • Docosahexaenoic acid (DHA) is an omega-3 fatty acid.
  • Eicosanoids

    • Eicosanoids are derived from either omega-3 (ω-3) or omega-6 (ω-6) EFAs.
    • The ω-6 eicosanoids are generally pro-inflammatory; ω-3s are much less so.
    • An excess of ω-6 to ω-3 fatty acids is common in western diets and is thought to encourage certain inflammatory disorders such as arthritis, cardiovascular disease, and cancers of the digestive system.
    • For each, there are two or three separate series, derived either from an ω-3 or ω-6 EFA.
    • These series' different activities largely explain the health effects of ω-3 and ω-6 fats.
  • Physical Characteristics of Urine

    • The pH of normal urine is generally in the range 4.6 - 8, with a typical average being around 6.0.
    • For example, high protein diets result in more acidic urine, but vegetarian diets generally result in more alkaline urine (both within the typical range of 4.6 - 8).
  • Internal Respiration

    • $Glucose + 6 Oxygen -> 6 Carbon Dioxide + 6 Water + 38 ATP$
  • Anatomy of the Small Intestine

    • The average length of the small intestine in an adult human male is 6.9 m (22 feet, 6 inches), and in the adult female 7.1 m (23 feet, 4 inches).
    • It can vary greatly, from as short as 4.6 m (15 feet) to as long as 9.8 m (32 feet).
  • RBC Anatomy

    • A typical human RBC has a disk diameter of 6–8 micrometers and a thickness of 2 micrometers, much smaller than most other human cells.
  • Mechanisms of Chemical Digestion

    • Glycogen is a multi-branched starch with linkages at the 1:4 and 1:6 position.
    • Both the parotid and pancreatic amylases hydrolyse the 1:4 link, but not the terminal 1:4 links or the 1:6 links.
    • This breaks amylose down into mainly disaccharides, and glycogen with its 1:6 linkages into polysaccharides .
    • Both the parotid and pancreatic amylases hydrolyse the 1:4 link, but not the terminal 1:4 links or the 1:6 links.
  • Pericarditis

    • The following is the clinical classification of acute versus chronic: clinically: acute (<6 weeks), subacute (6 weeks to 6 months), and chronic (>6 months)
  • Skin Cancer

    • D= "diameter" (larger than 6 mm—the size of a pencil eraser)
    • In comparison, the mortality rate of melanoma is 15-20% and it causes 6,5 thousand deaths per year.
  • Cytokine Therapy

    • Virtually all nucleated cells, but especially endo/epithelial cells and resident macrophages (many near the interface with the external environment) are potent producers of IL-1, IL-6, and TNF-α.
    • This results mainly in IL-1, IL-6 and IL-8 production.
