In addition, they may lower the HDL and increase the Triglyceride and lopoproteins level in plasma, therefore we should avoid food both with trans fatty acids as well as saturated fatty acids. 3.Terpene-belongs to a large class of hydrocarbon, with the molecular formula (C5H8)n, that are produced by a large variety of plants like the conifers. They are also produced by some other living organisms such as Swallowtail butterfl;ies, which emit Terpene from their Osmeterium, and a fungus isolated from St.John\'s Wort. terpenes are the primary constitutent of the Essential Oils of many plants and flower, such as Citrus Fruits. Terpenes are the major constitutent of resins as well as Turpentine from the resins. Apart from their roles as end products in many organisms, terpenes are the major biosynthetic building blocks within nearly every living creature.Eg-Steroids are derivative of the Triterpene Squalene. Carotenoids are terpenoids and a number of these can be made to Vitamin A. They are used to attract pollinating insects, and also used to provide defense mechanism by attracting animals such as mites. 4- Steroids are the type of lipid that contain four rings of Carbon atom. They can act as hormone in the body. The natural steroid hormone are synthesised from Cholesterol in the Gonads and the Adrenal Glands. These type of hormones are Lipids, and they can pass the cell membrane as they are fat soluble. The Cholesterol is the precursor of 5 major classes of the Steroid Hormone- Glucocorticoids and Mineralocorticoids (corticisteroid),these are produced by the Adrenal Gland, and the others -Androgens, estrogens and progestogens (produced in the gonads). 5- Simple Metabolite-Ceramide and Sphingisine-1-phosphate-They are important mediators in signalling cascades involved in apoptosis, proliferation, necrosis, imflammation, autophagy, senecence, and differentiation. 6-E 7-a 8-a-Van der waals contact 9-B 10-B 11-D 12-True-Lipids 13-C-Triglycerols 14-e-Glucocorticoids 15-Components of Wool Wax 16-d Physical state at room temperature 17-Glycerophospholipids Solution 1- D-These acannot be synthesised by the human body as we lack the DESATURASEENZYME required for their production. 2-d- The trans fatty acids increase the plasma Low density lipoprotein (LDL) cholesterol levels, when exchanged for cis unsaturated fatty acids.
