Fats/Lipids

Fats/Lipids

-It is composed of carbon, hydrogen, oxygen

-it is more concentrated source of energy

34%

What percent of the human body needs in fats/lipids?

Triglycerides/Fats/ Oils

-it is the fatty acids esters of glycerol

Lipids

It is the class of fats and fat related compounds

Structural Fat

-it is the fats that are not used and deposited

-it protects organ to prevent from shock/injury

Simple Lipids

Compound Lipids

Derived Lipids

Classification of Fats

Simple lipids

-aka neutral fats/ true fats

-Its chemical name is triglycerides

Triglycerids

-it is glycerol base with 3 fatty acids attached to it

Glycerol

It is derived from water soluble form of carbs

Compound Lipids

-it is the combination of fats with other compounds

Phospholipids

Glycolipids

Lipoprotein

There are 3 types under compound Lipids

Phospholipids

yolk and liver

Glycolipids

Lipoproteins

Both of them act as insulator around the nerve fibers

Phospholipids

It is compounds of fatty acids, phosphoric acid, and nitrogenous bases

Lecithins

Cephalins

Sphingomyelins

There are 3 types under phospholipids

Lecithins

-It is widely distributed phospholipids

-added to cheese, margarine to aid emulsification

(Type of phospholipids)

Cephalins

-it is needed to form thromboplastin

(Type of phospholipids)

Thrombloplastin

It is for the blood-clotting process

Sphingomyelins

It is found in the brain

(Type of phospholipids)

Glycolipids

-it is a fatty acid combined with carbs and nitrogenous bases

(Types of compound lipids)

Cerebrosides

Gangliosides

Types of glycolipids

Cerebrosides

It is the component of nerve and cell membrane (it plays a vital role in fat transport)

(Tyle of glycolipids)

Gangliosides

-it is made up of galactose, glucose and amino sugar

(Type of glycolipids)

Lipoproteins

-its lipids combine with proteins

-it is insoluble in water and combined in protein complex for transport and activity

(Classification of compound lipids)

Derived Lipids

It is simple derivatives from digestions

Fatty acids

Glycerol

Steroids

3 types under derived lipids

Fatty acids

-cell burns energy

-basic strutural unit of fat and it is saturated/ unsaturated

Saturated fats

Monosaturated fatty acid

Polyunsaturated fatty acid

There are 3 types of fatty acids

Saturated fats

-no hydrogen can be added

-abundant in animal fats

Oleic Acid

-most abundant MFA

-found in olive and peanut, oils

(type of monosaturated fatty acid)

Linoleic acid

It is most common Polyunsaturated fatty acid

Saturated - animal fat

Unsaturated - plant oil

Sources of Fatty Acid

Suet

It is a hard white fat on kidneys and loins of cattle, sheep and other animals

Mutton

It is a flesh of mature sheep

Tallow Yolk

-white nearly tasteless solid rendered fat of cattle and sheep

Glycerol

-it is water soluble component

-in digestion it becomes glucose

Steroids

-complex fat like compound found practically in all body tissue

Egg yolk

Organ meats

Shellfish

Dairy fats

Foods rich in cholesterol

95%

What percent does the fat is digestion and absorbed?

Adipose tissue

It is the continuing supply of energy

Fat protein sparing

Fat to maintain constant body temperature

Fat cushions vital organs

Fat absorption vitamins A, D, E and K

Fat delays hunger

Functions of Fats

Visible fats

Invisible fats

Two types of Foods sources of fats

Visible fats

It is lard, butter, margarine

Invisible fats

Milk, cheese, eggs

Cream, ice cream, bacon, butter, chocolates

High insaturated fatty acids

Lard

Fat from pig

Hydrogenated shortening

It turns liquid vegetables oil to solid

Pudding

Gelatin, cornstarch to create a sweet creamy dessert

Vegetable oils, sesame, mayonnaise, liquid oil, salmon

High in polyunsaturated fatty acids

Safflower

It is for diabetes, heart disease

Linoleic acid

-it is primary member of omega 6 family

-found in vegetables oils (corn, safflower)

-it can be made into arachidonic acid

Arichidonic acid

It is abundant in meat

Eicosapentaenoic acid (EPA)

Docosahexaenoic Acid (DHA)

Linoleic acid can be changed by the body into EPA and DHA, it helps prevent/ manage diseases like heart problems, what does those two means?

Omega 3 polyunsaturated fats

It lowers blood cholesterol

Cholesterol

It must not consumed more than 200 milligrams per day

Trans fat

-it is artificial fat

-it is in meat and dairy products

-it helps block arteries, raise the total and bad cholesterol levels

-it is made by chemical process called hydrogenation

Crackers, doughnuts, French fries, cookies,.pastries

Trans fat sources

Cancer

Diabetes

Liver toxicity

Obesity

Disease associated with eating trans fat foods

Eliminating trans fats

Fighting fats with fats

Cleanse, rejuvenate, and supplements

Steps in making changes
