Saturated and Unsaturated Fats
This is a paper on saturated and unsaturated fats. There are three references used for this paper.
There are a number of components in foods consumed by humans. It is important to understand what saturated and unsaturated fats are, as well as their functions.
Saturated Fats
Saturated fats are "any solid fat that is an ester of glycerol and a saturated fatty acid. The molecules of a saturated fat have only single bonds between carbon atoms (unknown)." These fats are characterized by maintaining a solid or almost sold form when stored at room temperature.
Saturated fats are considered to be extremely unhealthy. They are responsible for making the "body produce more cholesterol, which may raise blood cholesterol levels. Excess saturated fat is related to an increased risk of cardiovascular disease (www.dietsite.com/Diets/HeartHealthy/FatDictionary/Saturated%20Fat)."
Unsaturated Fats
Unsaturated fats are characterized by "double bonds in the fatty acid portion of the molecule. Unsaturated fats can be converted to saturated fats by a process called hydrogenation; since this usually raises the melting point of the fat and makes it a solid, the process is also called hardening (unknown)."
Unsaturated fats are considered to be good fats, and can be divided into two groups known as polyunsaturated and monounsaturated fats. Unsaturated fats can "lower LDL, the bad cholesterol, and raise HDL, the good cholesterol. Polyunsaturated fats contain omega-3 fatty acids, which can help prevent abnormal heart rhythms, improve the functioning of the heart and reduce risk of blood clotting. Monounsaturated fats contain vitamin E, thiamine, zinc, folate, niacin and antioxidants that help to fight illnesses such as heart disease and cancer (www.freep.com/news/health/diet9_20011009.htm)."
Conclusion
There are a variety of fats in the foods consumed today. It is important to understand the difference between these fats in order to maintain a healthy diet and prevent certain illnesses.

1992, the U.S. Department of Agriculture proposed the food pyramid as a tool of assessing the healthiness of a diet and as a proposal towards healthy living. While many of the issues that were relevant in the 1992 USDA food pyramid, such as "eating a variety of foods," balancing foods with physical activity" or moderate consumption of alcohol -- general indications for a healthy lifestyle -- the actual reference

There is a wide variety of such products and that includes salmon which grow twice as fast as the regular salmon, but nobody is thinking of the consequences when these fish will escape from the farms where they are being cultivated. Some types of plants like poplar, eucalyptus and pine are being modified so that their rate of growth increases and are able to stop reacting
These cells have an enzyme on their surface that attracts fat. The number and distribution of adipose cells has a genetic component, and is usually determined in early childhood. Describe the major metabolic diseases associated with lipid metabolism, transport and storage for humans? Diseases associated with lipid metabolism, transport and storage included: high cholesterol, combined hyperlipidemia, familial hypercholesterolemia, high density lipoprotein, and hypertriglyceridemia, How do unsaturated and saturated fatty acids differ from
