readily attained in commercial quantities from available raw materials. Organic oils are triglycerides or esters of fatty acids. They are chemical combinations of one molecule of glycerol with three molecules of fatty acids. When processed with caustic alkalis‚ they form soaps that are salts of fatty acids and glycerol‚ which is tryhydric alcohol. Yellow bell is a shrub with small‚ elongated branches and narrow alternate leaves. The plant requires direct sunlight. Quisumbing (1978) mentioned‚ that

Menthol Menthol is a synthetically-made organic compound extracted from natural plants like corn mint‚ peppermint‚ and other mint oils. It is a waxy and crystalline substance that is either clear or white in color. Due to its local anesthetic and counter-irritant qualities‚ it is widely used for a variety of purposes like soothing minor throat irritations‚ such as

researchers attempted to discover which bioplastic would be more viable for both industrial and personal use‚ in terms of its tensile strength‚ flexibility‚ water resistance and mouldability. In the procedure‚ for the first set-up‚ vinegar‚ glycerol and water were mixed in a bowl together with potato starch. The second set-up had a similar mixture‚ although instead of adding potato starch‚ agar-agar was used. Both mixtures were heated until they reached about 95 ͦC. Thereafter‚ half of the solutions

solutions of about pH10. When the pH drops below pH 8.3 phenolphthalein will go colourless. Here‚ an alkaline solution of milk‚ lipase and phenolphthalein will change from pink to colourless as the fat in milk is broken down to form fatty acids (and glycerol) thus reducing the pH to below 8.3. The time taken for this reaction to occur is affected by temperature. AIM To investigate the effects of increasing temperature on the activity of enzyme Lipase.

Osmosis The purpose of this lab is to study how membranes of plant and animal cells react when exposed to different solutions. The first experiment involves purple onion skin and the second involves rat blood in various solutions. I needed to understand certain terms before preforming this lab to be able to efficiently explain what is happening to the cells. Diffusion is the tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.

are nonpolar‚ insoluble molecules gained within the body trough digestion of food. Triglycerides‚ a type of lipid that serve as storage units for energy have 3 fatty acid chain tails made up of carboxylic acid and a fatty carbon chain attached to a glycerol backbone. These molecules can be saturated or unsaturated contingent on the bond types and hydrogen number in the molecule. Anytime a fatty acid is removed from a glyceride molecule‚ dehydration synthesis occurs and a water molecule is taken away

• Organic chemistry- special study of chemistry dealing with molecules containing carbon and hydrogen • Hydrocarbon- an organic molecule consisting only of carbon and hydrogen. • Functional groups- a specific configuration of atoms commonly attached to the carbon skeletons of organic molecules and involved in chemical reactions. • Hydroxyl group: a chemical group consisting of an oxygen atom joined to a hydrogen atom. Molecules possessing this group are soluble in water and are called alcohols
