What is Which of these fatty acids is found exclusively in breast milk: and explain in detail?
D i.e. Docosahexanoic Acid Most of the naturally occurring unsaturated fatty acids are cis-isomers. Trans-FA do not occur naturally in plants and occurs only in small amounts in animals as ruminant fat (eg butter fat) arising from the action of micro organisms in rumen. Cis isomers are less stable than trans FA.- Trans fatty acids formed during paial hydrogenation or hardening (saturation /deep frying)Q of vegetable oils - a procedure to improve stability or shelf life. Trans - FA increase incidence of coronary hea disease by increasing LDL and decreasing HDLQ.- Linoelic acid is the most impoant essential fatty acid because it serves as the basis for production of other EFAs like arachidonic acid & docosahexanoic acid. Arachidonic acid, a w-6 PUFA is essential as it is a precursor of prostaglandins & leukotrienes.Linoleic acid is the most impoant essential fatty acid, maximally found in Safflower oilQ>Corn oilQ> Sunflower oilQ- Docosahexanoic Acid (DHA; tai, 22:6) which is synthesized from a-linolenic acid or obtained directly from fish oils, is present in high concentrations in retina, cerebral coex, testis & sperm. DHA is paicularly needed for development of brain & retina and is supplied the placenta and milk. Milk is the constant and continuous source of DHA as placenta is not present at all time. Patients with Retinitis pigmentosa are repoed to have low levels of DHA.Plasma membrane contains both saturated & mono or poly unsaturated FA.
