Document Summary

Most nonliving things are made of inorganic molecules. Living things are made of organic molecules: carbon is the backbone for organic molecules. Carbohydrates (sugars: cnh2non, monosaccharide is a single unit of glucose, disaccharide 2 sugars. Two monosaccharides linked by a dehydraion synthesis reacion to form a glycosidic bond: polysaccharide 3+ sugars. Macromolecules formed by the polymerizaion of many monosaccharides subunits (monomers) Starch some branches, energy storage in plants. Glycogen highly branched, highly soluble, short term energy storage in animals. Cellulose mad by plants as a structural iber in cell walls: glucose blood sugar. Molecular bonds are broken down by cells to give you energy. 1: complex carbohydrates long, branched chains of monosaccharides, can appear in both a linear form and ring form, dehydraion synthesis (condensaion synthesis) when smaller molecules bond as water is given of (the loss of h2o) Lipids (faty acids: hydrophobic, non-polar molecules, 3 types. Faty acids (triglycerides) long term energy storage, structural support, and insulaion.

When two of these carbohydrate monomers are bonded together what "class" of carbohydrate is formed? What are the types of this "class"? What is the source (food) for each of these?

When three or more of these monomers are bonded together they form which "class" of carbohydrate? Which one of these stores excess carbs in animals (mainly in the liver)? Which one stores excess carbs in plants? And which one is indigestible by the human gut, but is important because it provides "bulk" in the form of fiber and helps keep fecal matter moving in the intestines?

What is the monomer of nucleic acids?

Briefly describe deoxyribonucleic acid including its general function.

Briefly describe ribonucleic acid including its general function.

What are the monomers of proteins? What kind of bond holds the monomers together?

Distinguish between oligopeptides and polypeptides.
