1 Lipids
Copy
There is more than one kind of fat.
Saturated FatSaturated fat is an unhealthy fat that is naturally found in foods from animals such as fatty cuts of meat, poultry with the skin on and higher fat milk, cheese and yogurt. Saturated fat is also found in tropical oils, including coconut and palm kernel oils.
May cause clogging of arteries (atherosclerosis), heart disease, stroke, obesity
2 Fats
Copy
Unsaturated FatsAre healthy fats that include Omega 3 fatty acids & Omega 6 fatty acids.
Omega-3 fats are found in fatty fish such as salmon, mackerel, trout, herring and sardines. They are also found in oils and some soft margarines.
Omega 6 are found in nuts and seeds.
Helps with the development of the nervous system, improves circulation

4 Fats

Hydrogenated Trans Fats
Trans fat is an unhealthy fat. It is made out of liquid oil that is then changed into a solid fat. Trans fat adds texture and flavor to food. It is most often found in commercially baked goods, fried foods and processed foods like packaged salty snacks and convenience foods including frozen foods.
Avoid lead to heart disease
5 Phospholipids
Copy
form the chief component of all cell membranes
6 Cholesterol
Copy
- helps stabilize all animal cell membranes - used by the body to synthesize steriod hormones such as sex hormones (testosterone, estrogen) and hormones of the adrenal cortex, Vit. D synthesis (assists with bone development), and synthesis of bile (produced by liver, breakdown of lipids)

8 How To Test For Fats
Copy
Two Tests
1) Sudan IV if fat is present it turns solution from pink to red
2) Translucence lipid test if light is transmitted through the brown paper, fat is present
