\nwhere the three alkyl groups R1<\/sub>, R2<\/sub> and R3<\/sub>\u00a0may be the same or different.<\/li>\n<\/ul>\nWhy does our body need oils and fats?<\/strong><\/h2>\n
\n
\nFats and oils serve as the most efficient means for living things to store energy. They are thus an important source of energy. Like carbohydrate, fat releases energy when it is oxidised to carbon dioxide and water. They supply us with more energy per gram than carbohydrates.<\/li>\n
\nWe need to include vitamins as part of a balanced diet to maintain good health. Vitamins A, D, E and K are insoluble in water but soluble in fats. We can meet our vitamin requirements by consuming foods that contain these fat-soluble vitamins.<\/li>\n
\nFat plays important structural roles in the body. The protective membrane of each body cell is made from fat molecules. Even the nucleus of the cell is protected by layers of fat molecules.<\/li>\n
\nThe layer of fat under our skin is to protect us from the cold and to protect our internal organs from freezing. The layer of fat under the skin acts as a thermal insulator.<\/li>\n
\nFat surrounds and protects vital internal organs in our body. For example, kidney is protected by a layer of fat.<\/li>\n<\/ol>\n\n

\n<\/li>\nHow do saturated and unsaturated fats affect the body?<\/strong><\/h2>\n
\n
\n(a) Fatty foods are very high in energy.<\/strong> One gram of fat releases about 9 kilocalories of energy. Hence, high consumption of food high in fats and oils is likely to result in obesity.
\n(b) An obese person is prone to suffer from heart disease and other diseases such as diabetes.<\/li>\n
\n(a) Consuming food high in saturated fats will raise the level of cholesterol<\/strong> in the bloodstream. It is the cholesterol which causes fatty deposits or plaque<\/strong> on the walls of veins or arteries. As the plaque builds up on the walls of the blood vessels, blood circulation is restricted and this will raise blood pressure.<\/strong>
\n(b) Hardening of the arteries occurs if the deposits take place in the heart arteries. A condition called arteriosclerosis occurs, preventing adequate supply of blood from reaching the heart and can cause heart attack.
\n(c) High-density lipoproteins<\/strong> (HDL) is called the \u2018good\u2019 cholesterol because it can reduce the risk of heart disease. High levels of low-density lipoproteins<\/strong> (LDL), the \u2018bad\u2019 cholesterol, increase the risk of heart disease.<\/li>\n
