1
Are organic compounds(saccharides, starches and sugars) composes of carbon, hydrogen and oxygen • They provide the major source of energy for the body or as much as 80 to 100% • ( “GO” Food ) • The main source of energy for man provides heat to maintain body temperature • Broken down into sugars during ingestion • The cheapest among all food stuffs fiber • part of plant food which when eaten is the indigestible part of food • Acts as a broom in our digestive tract to prevent constipation
CARBOHYDRATES
2
simple sugars is the simplest form of carbohydrates
MONOSSACHARIDE
3
•Abundant in fruits, sweet corn, corn syrup. Moderately sweet sugar •It Stores in the Liver 1/3 of body’s total glycogen •Muscle cells stores glucose as glycogen.
Glucose(Dextrose)
4
, also known as “ketone bodies,” are by products of the body breaking down fat for energy that occurs when carbohydrate intake is low
Ketones
5
is a metabolic state in which some of the body's energy supply comes from ketone bodies in the blood, in contrast to a state of glycolysis in which blood glucose provides energy.
Ketosis
6
•The sweetest of all simple sugars and can be converted in glucose in the body
Fructose (levulose)
7
•Not found free in foods it is produced from lactose (milk sugar)
Galactose
8
Inability to metabolize galactose
Galactosemia
9
They must changed to simple sugars by hydrolysis before the can be absorb
DISACCHARIDES OR DOUBLE SUGARS •
10
processed from cane and beet sugar, fruits, vegetables syrups, sweet food production and is converted to glucose and galactose upon digestion. Compose of glucose in digestion.
Sucrose
11
milk and milk products. It is converted to glucose and galactose in digestion. It remains in the intestine longer than other sugars
Lactose
12
It is produced by hydrolysis of starch and converted to glucose. It occurs in the malt products. It is less sweet compare to glucose and sucrose.
Maltose
13
Are composed of many molecules of simple sugars
POLYSACCHARIDES (Complex Sugars)
14
•the most significant polysaccharide •It is converted entirely to glucose upon digestion and are more complex than sugars
Starch
15
•Are found free in foods. They are formed as intermediate products in the breakdown of starch.
Dextrin
16
•Forms the framework of plants found in unrefined grains and vegetables and fruits •A non-digestible enzyme and provides important bulk in the diet which helps move digestive food mass along and stimulates peristalsis •Lowers blood glucose levels of people with diabetes mellitus.
Cellulose
17
- found in fruits and legumes, barley and oats which delay gastrointestinal transit, delay glucose absorption.
Soluble
18
– found in wheat bran, corn bran, whole grain bread, cereals and vegetables which accelerates gastrointestinal transit. Increase fecal weight, slow down starch hydrolysis and delay glucose absorption.
Insoluble
19
•are non-digestible, colloidal polysaccharides having a gel quality •It sources includes mostly fruits and are often used as a base for jellies. •Pectins are also used in the treatment of diarrhea.
Pectin
20
(animal starch) are formed from glucose and stored in the liver and muscle tissue. Its food sources are mainly meat and sea foods. It is converted to glucose upon digestion. •The hormone glucagon help the liver convert glycogen to glucos
Glycogen
21
1. Enzyme- amylase(an enzyme of the saliva secreted by the parotid glands, acts on starch to begin its breakdown to its breakdown to dextrin and maltose 2. Action – conveyed into the stomach mostly in starch form.
Mouth
22
1. Enzyme – none for the carbohydrates 2. Action – none; above action by ptyalin may continue to a minor degree.
Stomach
23
1. Enzyme- Pancreatin Enzyme- amylopsin –converts-starch to dextrins and maltose 2. Intestinal Juice – which contains three disaccharides sucrose, lactose, maltose
Small Intestine
24
the amount of CHO is ? gm.
365
25
SOURCES OF CARBOHYDRATES
1. Whole grains 2. Sweet potatoes and white potatoes, bananas 3. Sugar and sweets 4. Milk
26
Health Effects
1. Weight Control 2. Heart Disease 3. Cancer- protects in many type of cancer 4. Diabetes 5. Gastrointestinal health
