saturated fat term applied to a lipid compound with the maximum number of hydrogen atoms, where there are no double or triple bonds between the carbon atoms.

|
 |
|
 |
Saturated Fatty Acid A saturated fatty acid is an acid which, by definition, has no available bonds in its hydrocarbon chain; all bonds are filled or saturated with hydrogen atoms. Thus the chain of a saturated fatty acid contains no double bond. The saturated fatty acids are more slowly metabolised by the body than are the unsaturated fatty acids.
Saturated fatty acids include acetic acid, myristic acid, palmitic acid, and steric acid. These acids come primarily from animal sources, with the exception of coconut oil, and are usually solid at room temperature. In the case of vegetable shortening and margarine, oil products have undergone a process called "hydrogenation", in which the unsaturated oils are converted to a more solid form. Other principal sources of saturated fats are milk products and eggs. |

Sickle cell anemia a hereditary disease in which a mutation in the gene for one of the proteins that comprises hemoglobin results in the formation of defective hemoglobin molecules known as hemoglobin S.

These sickle-shaped cells are easily trapped in capillaries and damaged, resulting in severe anemia. Individuals who are heterozygous for the mutation (possess one gene for hemoglobin S and one normal hemoglobin gene) have increased resistance to malaria. |

Silicon containing substances are found in all cartilage and in the material binding cells together. Silicon may be needed for proper bone structure and growth. |

Simple Carbohydrates Simple carbohydrates are monosaccharides and disaccharides occurring naturally in fruits, vegetables, and dairy products. Some examples of simple carbohydrates are glucose, galactose, and fructose, all of which are monosaccharides and, sucrose, lactose, and maltose, all of which are disaccharides.
Most simple carbohydrates elevate blood sugar levels rapidly, providing "instant energy" which is quickly utilised and dissipated. Fructose is an exception. Additionally, refined sources of simple carbohydrates, such as candy, contribute only calories to the diet. These "empty calories" are often consumed in place of foods which would provide important nutrients in addition to the energy. |

Speed-Strength A type of strength typically referred to as power. Power, however, is an inadequate term as it does not differentiate between the two important types of speed-strength.
1.Starting strength involves turning on a maximum number of muscle fibres instantly in any given movement. Ballistic athletes, such as a sprinter, need this strength the most to make his muscles fire simultaneously with each stride. A boxer does the same with each punch, a baseball pitcher each time he hurls.
2.Explosive strength describes the firing of muscles fibres over a longer period of time after initial activation, for the purpose of pushing, pulling or moving a weighted object. Examples: weightlifting, shot-put and football.
