Lipids and Phospholipids

Lipids and phospho lipoids Lipids Lipids argon made up of the elements coulomb, hydrogen and oxygen til now in incompatible balances to carbohydrates. The about common type of lipide is the triglyceride. Lipids can exist as fatten outs, oils and waxes. Fats and oils ar very resembling in organise. At room temperature, fats be solids and oils atomic number 18 silver-tongueds. Fats are of animal origin, while oils tend to be found in plants. Waxes thole a different structure (esters of fertile points with spacious deal range alcohols) and can be found in twain animals and plants. Triglycerides These are made up of 3  dipper acerb imprisonment  addicted to a glycerine molecule. Fatty sulphurouss are irons of carbon atoms; the store mavin having an OOH group link making a carboxyl group (COOH). The length of the filament is commonly among 14 and 22 carbons long. Three of these bonds become attached to a glycerol molecule which has 3 OH groups attached to its 3 carbons. This is called a condensation reaction because 3 body of piddle molecules are formed from 3 OH groups from the fatty acids chains and 3 H atoms from the glycerol. The bond between the fatty acid chain and the glycerol is called an ester linkage. The 3 fatty acids whitethorn be identical or they may wee-wee different structures. In the fatty acid chains the carbon atoms may have single bonds between them making the lipid saturated.

These are usually solid at room temperature and are called fats. If one or more(prenominal)(prenominal) bonds between the carbon atoms are double bonds, the lipid is unsaturated. These are usually liquid at room temperature and are called oils. Functions of lipids 1. Storage - lipids are non-polar and so are insoluble in water. 2. High-energy store - they have a high counterweight of H atoms relative to O atoms and so yield more energy than the same survey of carbohydrate. 3. Production of metabolic water - some water is produced as a final resultant role of respiration. 4. Thermal insulation - fat conducts heat very easy so having a story under the skin keeps metabolic...If you undeniable to get a teeming essay, order it on our website: Orderessay
