SAS3-PART 2 Flashcards
The lipids in food and in the human body include
TRIGLYCERIDES (FATS AND OILS)
PHOSPHOLIPIDS
STEROLS
Functions of fat in the body
ENERGY STORES
MUSCLE FUEL
PADDING
INSULATION
CELL MEMBRANES
RAW MATERIALS
Are the body’s chief form of stored energy
FATS
Fats are converted to other compounds such as
HORMONES
BILE
VITAMIN D
When people talk about fat, they are usually referring to
TRIGLYCERIDES
Predominate both in the diet and in the body
TRIGLYCERIDES
The name triglyceride almost explains itself:
three(tri) fatty acids attached to a glycerol
When energy for any energy yielding nutrient is to be stored as fat, the nutrient is first broken into small fragments. Then the fragments are linked together into chains known as
FATTY ACIDS
Solid at room Temperature and can be found in meat butter and dairy products
SATURATED FATS
Too much consumption of thesefats (saturated) can increase the levels of
LOW DENSITY LIPOPROTEINS (LDL)
Low density lipoproteins also known as the
BAD CHOLESTEROL
Liquid at room temperature and can be found in vegetable oil
UNSATURATED FATS
These fats increase the levels of good cholesterol or the ________
UNSATURATED FATS
HIGH-DENSITY LIPOPROTEIN
HDL grabs LDL to escorts it on the _____ ‘Where’ LDL is broken down and eventually removed from the body
LIVER
An unhealthy substance that is made through the chemical process of hydrogenation of oils
TRANS FATTY ACIDS
Trans fatty acids both raise the bad ldl cholesterol and lower the good cholesterol levels in blood, markedly increasing the
RISK OF HEART DISEASE
Using carbohydrate fat or protein the human body can synthesize all the fatty acid it needs except for two
LINOLEIC ACID AND LINOLENIC ACID
Both linolec acid and linolenic acid are
POLYUNSATURATED FATTY ACIDS
Because they cannot be made from other substances in the body, they must be obtained from food and are therefore called
ESSENTIAL FATTY ACIDS
Are found in small amounts in plant oils, and the body released or stem making deficiencies unlikely
LINOLEIC ACID AN OMEGA 6 FATTY
LINOLENIC ACID AN OMEGA 3 FATTY ACIDS
These two essential nutrients are also serve as structural components of cell membranes
LINOLEIC ACID AN OMEGA 6 FATTY ACID
LINOLENIC ACID AN OMEGA 3 FATTY ACID
One of the three main classes of lipids; that are similar to triglycerides but have choline and a phosphorus-containing acid in place of one of the fatty acids
PHOSPHOLIPIDS
The richest food sources of lecithin are
EGGS LIVER SOYBEANS WET GERM AND PEANUTS
In addition to the phospholipids used by the food industry as,______. Phospholipids are also found naturally in foods
EMULSIFIERS
