Carbohydrates Flashcards
Glucose
Primary source of energy of cells, Brain and nervous system use about 150g/day
Fructose
Fruit sugar/levulose, Isomer of glucose
Galactose
Part of lactose, Converted to glucose by liver
Maltose
2 Glucose, Intermediary product during digestion of starch and germination of seeds
Lactose
Glucose and Galactose, 30-50% milk energy
Sucrose
Glucose and Fructose, Saccharose (name)
Glycogen
Poly, Form of stored glucose, Highly branched for hydrolysis
Starch
Poly, Form of stored glucose in plants, richest in grains
Fiber
Poly, Non-digestible, Cellulose, Hemicellulose, Pectins, Gums and Mucilages, Prevents appendicitis, hemorrhoids and diverticulitis, Weight and diabetes control, Lower cholesterol
Glucose Homeostasis
Blood glucose rise = Pancreas release insulin = Glycogen and fat = Decline
Glucagon release = Liver breaks down Glycogen
Diabetes
Inadequate insulin, Polyurea, Polydipsia, Polyphagia, Type I = IDDM, Type 2 = NIDDM
Glycemic Effect
Extent to which food raises blood glucose and elicits insulin
Lactose Intolerance
Deficiency of lactase (Bloating, Diarrhea, Abdominal discomfort, Nausea)
Dental Caries
Erosion in tooth surface by acid or bacteria
Carbohydrate Intake
Sugar (less than 10%), Starch and fiber (55%-60% and 20-35g)
