Term
Starch
Definition
Plant polysaccharide composed of glucose
Term
Glycogen
Definition
Highly branched polysaccharide, Made & stored by liver and muscle tissue, Not complex carb
Term
Soluble Fibers
Definition
Food components that readily dissolve in water, Indigestible by enzymes but broken down by bacteria to be absorbed
Term
Insoluble Fibers
Definition
Tough, fibrous structures of fruits, veggies & grains, Indigestible food components, Don't dissolve in water
Term
Constipation
Definition
Difficult, incomplete or infrequent bowel movements, Dry, hardened feces
Term
Diverticulitis
Definition
Painful inflammation of the diverticula (sacs that balloon out of intestinal wall)
Term
Lactose Intolerance
Definition
Impaired ability to digest lactose due to reduced amounts of enzyme lactase
Term
Lactase
Definition
Intestinal enzyme that splits disaccharide lactose to monosaccharides during digestion
Term
Amylase
Definition
Enzyme that breaks down starch of sugar, In human saliva
Term
Protein-sparing Action
Definition
Carb & fat providing energy that allows protein to be used for purposes alone can serve
Term
Ketone Bodies
Definition
Acidic fat compounds come from incomplete fat breakdown when carb isn't available
Term
Insulin
Definition
Secreted by pancreas when high blood glucose, Takes glucose from blood
Term
Diabetes Warning Signs
Definition
Excessive urination & thirst, Glucose in urine, Weight loss, Craving for sweets, Frequent infections, Blurred vision
Term
Ketosis
Definition
Undesirable high concentration of ketone bodies in blood or urine
Term
Glucagon
Definition
Secreted by pancreas stimulates liver to release glucose in blood when glucose is low
Term
Diabetes
Definition
Disease with elevated blood glucose & inadequate insulin impairs person's ability to regulate blood glucose
Term
Type I Diabetes
Definition
Pancreas produces no/very little insulin, Often diagnosed in children
Term
Type II Diabetes
Definition
Pancreas makes plenty of insulin but cells resist action, Often diagnosed in adults
Term
Insulin Resistance
Definition
Condition where high insulin level produces not normal response in muscle, liver & adipose tissues
Term
Hypoglycemia
Definition
Blood glucose concentration below normal
Term
Postprandial Hypoglycemia
Definition
Unusual drop in blood glucose that follows meal, Symptoms include anxiety, rapid heartbeat & sweating
Term
Lipid
Definition
Family of organic compounds soluble in organic solvents but not water, Include triglycerides, phospholipids & sterols

Soft, waxy substance made in body & found in animal derived foods
Term
Fats
Definition
Lipids that are solid at room temp
Term
Oils
Definition
Lipids that are liquid at room temp
Term
Cardiovascular Disease
Definition
Disease of heart & blood vessels
Term
Triglycerides
Definition
Chief form of fat in foods and body, Made of 3 units of fatty acids & 1 unit of glycerol
Term
Phospholipids
Definition
Similar to triglycerides but has phosphorus containing acid in place of fatty acid, Present in cell membrane
Term
Sterols
Definition
Similar structure to cholesterol
Term
Essential Fatty Acids
Definition
Body needs but can't make in sufficient amounts to meet physiological needs
Term
Fatty Acids
Definition
Composed of carbon chains of various lengths, Each had acid end & hydrogen attached to all carbon atoms
Term
Glycerol
Definition
3 carbons long, Triglyceride backbone
Term
Saturated Fatty Acids
Definition
Carrying max possible hydrogen atoms
Term
Point of Unsaturation
Definition
Site in molecule where hydrogen atoms can easily be bonded
Term
Unsaturated Fatty Acids
Definition
lacks some hydrogen atoms and has points of unsaturation
Term
Monounsaturated fatty acids
Definition
Containing one point of unsaturation
Term
Polyunsaturated fatty acids
Definition
Containing two or more points of unsaturation
Term
Saturated Fats
Definition
Triglyceride where most fatty acids are saturated
Term
Trans fat
Definition
Fats that contain any number of unusual fatty acids (formed during processing)
Term
Monounsaturated fats
Definition
Triglycerides where most fatty acids have one point of unsaturation
Term
Polyunsaturated fats
Definition
Triglycerides where most fatty acids have 2+ points of unsaturation
Term
Emulsifier
Definition
Substance mixes with fats & water
Term
Bile
Definition
Emulsifier that splits fatty acids from their glycerol for absorption
Term
Monoglycerides
Definition
Products of lipid digestion, Consist of glycerol molecules & one fatty acid
Term
Lipoproteins
Definition
Clusters of lipids assoc with protein, Serve as transporters for lipids in blood & lymph
Term
