Overview

Today is a 42 minute review of carbohydrates and lipids.

5 carbon sugars are for storage, as in RNA and DNA.  Ribose and deoxyribose.

6 carbon sugars are used for energy – glucose, fructose and galactose.  Chemical isomers.

Dehydration synthesis reactions lose water and join monomers.

Hydrolysis – water to break apart – produce water and break bonds.

Making bonds releases energy, breaking bonds costs energy, from regular chemistry.

sucrose – glucose + fructose

lactose = glucose + galactose

galactose = glucose + glucose

Polysaccharides are polymers of glucose – CxH2xOx.

Starch/amylase.  Plants store glucose as a polysaccharide called starch – potatoes, rice, corn, bread.  Animals do not have starch.

Cellulose makes up the cell walls of plants.  It’s the site of water insoluble fiber in diet.  We cannot digest cellulose and it passes out of the stool.  It’s less obvious in adults, but you can see this easily in kids.

Lack of fiber weakens and thins the walls of the digestive tract.  This is called diaparticulosis.  The large intestine can protrude and become infected.  The intestinal tract has smooth muscle with peristaltic contractions that move food along.  This makes the muscles work.  The muscle can atrophy.

Animals store glucose as glycogen.  Animal starch.  It’s stored mostly in the liver cells as liver glycogen.  Also in the skeletal muscles as muscle glycogen.

Water and salt are the only two things in our bodies that didn’t come from living things.

Lipids

…are hydrophobic, non polar and insoluble in water.  Contain more stored energy than any organic molecule (9 kcal/gram).  Fatty acids have a carboxylic acid group on the end, COOH.

Saturated fatty acids have the maximum number of hydrogens.  Solid at room temperature.  Synthesized in animals.  Butter, lard, tallow

Unsaturated acids have at least one double bond.  Liquid at room temperature.  Vegetable oils are mostly unsaturated.  Olive oil, canola oil.

The saturated C-H bond has more energy than any C-O, C=O bond.

Plaque is a fat on the inner walls of the arteries made up of saturated fat and cholesterol.  Increases risk of blood clots.  Number one cause of death is heart attack; a stroke is a blood clot in the brain.

Fat        Saturated    Unsaturated

Corn Oil           13     87

Butterfat         66 34

Coconut Oil   92   8

Beef Tallow     52   48

Tropical oils include coconut oil and palm kernal oil.  They taste the best.  Non dairy creamers and non dairy ice creams are made from these.  No cholesterol in plant oils.

We need unsaturated fatty acids in our diets.

Unsaturated fats can be easily converted into saturated fats to increase storability.  This is hydrogenation.  No healthier than butter itself.
