COMPONENTS of carbs
Carbs (CHO) is a chemical compound made of carbon , hydrogen, oxygen.Basic unit of carb is monosaccride .Carbs are mainly required to obtain energy in a living body. It is stored in form of starch in plants and glycogen in animals . Glucose a monosaccride is most common sugar which is used to Store and release energy.
CLASSIFICATION of carbs
Monosaccrides - Glucose , fructose , galactose.
Disaccharides - Sucrose, lactose, maltose.
Polysaccharides- They are further distributed into two forms
Digestible- starch, dextrin, glycogen.
Indigestible- cellulose, hemicellulose (pectin,agar-agar)
STARCH
It is primary source of energy in diet.starch on partial hydrolysis gives dextrin.
Resistance starch escapes digestion in small intestine.These forms are named RS1,RS2,RS3 . Glycogen is form of animal starch.
Cellulose & hemicellulose
Abundantly found in nature in seedcoats, skin of fruits.They are very rich in nutrition as a large proportion of dietary fibre.They are indigestible by human digestive system.
Helps in
• Increasing bulk matter
• stimulation of peristaltic movements
• aid in evacuation of bowel
• prevent constipation
Pectins main property is to absorb water and form easy gel.
FUNCTIONS
• Source of calories each gram of carbs gives 4 cal
• Spare protein for its functioning .
• Adequate supply of carbs determine fats to be metabolized for energy.In absence of carbs more fat is used and ketones accumulation takes place.
• anti- Ketogenic effect
• lactose encourage growth of favourable intestinal bacteria.
• laxative property
• enhance calcium absorption.
• Glucose source of energy for CNS
• cellulose provide feacal bulk.
DEFICIENCY SYMPTOMS
• Accumulation of large amount of ketones cause ketosis or acidosis ( uncontrolled diabetes).
EXCESS of CHO cause
• Dental caries
• obesity
• irritate gastro intestinal mucosa
• depress appetite
• increase blood triglycerides level leads to heart diseases
