Nutrition: Lipids Fats: are the most concentrated of the
energy-producing nutrients Animal fats:
from eggs, dairy products, and meats high in saturated fats and cholesterol
Vegetable fats: from avocados, olives, some nuts, and certain
vegetable oil rich in monounsaturated and polyunsaturated
fat.
Lipids Excess food is stored as fat in animals.
It is found in tissues and as butterfat in milk and other dairy products.
Recall Carbohydrates, to answer the following:
To break down the fat molecule to use it for energy or building blocks, we would add ….., in the process called...
Water…….Hydrolysis.
Lipid Functions
stored in the body cushions vital organs
protects us from extreme cold builds cell membranes helps the body absorb some
vitamins
Macromolecules: Lipids
Lipids are macromolecules made of carbon, hydrogen, and oxygen (C,H,O). The ratio of hydrogen to oxygen is
much greater than 2:1. (Waaaay more H’s)
Lipids are made of fatty acids attached to alcohol.
Lipids: Triglycerides Useful for long-term storage of energy;
warmth; organ protection (cushion) What reaction took place?
Lipids: Saturated versus Unsaturated Fats
Too much fat = bad (heart disease) Unsaturated better than saturated
Also called trans fat
Lipids: Cholesterol Cholesterol is a large
lipid molecule located in the cell membranes of animals (helps to make it not so fluid).
In excess, it can form deposits and clog up the inner walls of blood vessels
