Disaccharides

Double sugars. Hydrolysis to monosaccharides. Examples are sucrose maltose and lactose

Lactose intolerance

Inability to digest lactose because if you lack of the enzyme lactase; causes abdominal cramps and diarrhea

Polysaccharides

Complex carbohydrates containing combinations of monosaccharides. Examples include starch dextrin cellulose and glycogen

Glycogen

Fiber

Indigestible parts of plants; absorbs water in large intestine, helping to create soft stool.

Cellulose

Primary sources of dietary fiber

Endosperm

Lipids and fat

Formed from glycerol Provides energy. 9 calories

hypercholesterolemia

Unusually high levels of cholesterol and blood; also known as high serum cholesterol. Common in clients with atherosclerosis.

plaque

Fatty deposit on interior of artery walls. When plaque blocks the heart a heart attack occurs. When it blocks the brain a stroke occurs.

function of stomach

temporary storage of food. mixing of food with gastric juices. regulation of a slow, controlled emptying of food into the intestine. sexretion of the factor for B12. destruction of most bacteria.

sphincter malfunction

causes acid reflux disease.

chyme

food mass as it has been mixed with gastric juices

gastric juices

digestive secretions in stomach. contain HCl, pepsin, mucus. HCl activates pepsin to digest protein. children have two additinal enzymes rennin-milk protein, and gastric lipase-butterfat

salivary amylase

component of saliva that starts the digestion of starch in the mouth

duodenum

Chyme moves through the pyloric sphincter into the duodenum the first section of the small intestine.

secretin

hormone that is released when food reaches the small intestine that causes the pancreas to release sodium bicarbonate to neutralize chyme

cholecytokinin (cck)

triggers gallbladder to release bile for the digestion of fat

pancreatic proteases

the enzyme secreted by the pancreas that digests proteins

pancreatic amylase

converts starches to simple sugars

pancreatic lipase

reduces fats to fatty acids and glycerol

small intestine in digestion

most nutrients absorbed. breaks down lactose maltose and sucrose.

peptidases

break proteins down into amino acids

colon

large intestine. funtion: absorb water and salts from undigested food. makes volatile acids.

volatile fatty acids

acetate, propionate, butyrate. absorbed from large intestine and used as energy.

organic compounds that enable the body to use energy provided by fats carbs and proteins. can not cure.

fat soluble vitamin deficency

occur in those with chronic malabsorbtion disease such as cystic fibrosis, celiac, and chrons disease.
