Transcript of Carbs and Lips

Carbohydrates and Lipids Some Examples of Carbs would Be:
Watch this video:
Biochemistry is the study of the chemicals and reactions in living things.
Carbohydrates and Lipids are two examples of biochemical molecules. Carbohydrates are molecules that are composed of carbon, hydrogen, and oxygen atoms in a 1:2:1 ratio, and provide nutrients to the cells of living things. Sugars, Starches, and Cellulose. By: CJ Ogalla First you need to know that: Second let's focus on Carbs: Carbs continued... Carbs are produced in plants during photosynthesis.
Because animals CANNOT make their own carbohydrates, they must get them through food.
Carbs supply nearly all the energy in food from plants!!! Monosaccharides -this is a simple sugar that is the basic subunit of a Carbohydrate
It contains 3-7 Carbon atoms
It usually is a sweet tasting white solid at room temp Examples of Monosaccharides Glucose-the most abundant monosaccharide in nature
Fructose-the sugar in fruit and honey Video on Monosaccharides Let's take it one step further with Disaccharides... -these are sugars that consist of 2 monsaccharides combined together. For Example: Sucrose is a disaccharide that consists of a glucose molecule and a fructose molecule bonded together.
Another disaccharide is lactose-or the sugar found in milk. Did you know that when you ask for sugar you are most likely asking for sucrose (table sugar)? It consists of 12 Carbon atoms, 22 Hydrogen atoms, and 11 Oxygen atoms. AND EVEN FUTHER WITH OUR OLD FRIENDS POLYSACCHARIDES... A Polysaccharide is a carb made up of long chains of simple sugars. Some examples would be cellulose, starch, and glycogen. Humans cannot digest cellulose by themselves; we need fiber to move it through our system. ANd of course a polysaccharide video... Finally let's wrap it up with lipids.. these are a type of biochemical that do not dissolve in water, have a high percentage of C and H atoms, and are soluble in nonpolar solvents. Long chains of fatty acids, phospholipids, steroids, and cholestoral are lipids. Fatty acids are the simplest lipid molecules. -an example would be oleic acid. movie time!!! THE END... And what better way to end than with a depressing song?...
