Document Summary

Organic molecules can be natural or synthetic. Because carbon has 4 valence electrons so it can be combined with any element and can be arranged into chains and rings. Carbon is unparalleled in its ability to form large, complex, and diverse molecules. Proteins, dna, carbohydrates, and other molecules that distinguish living matter are all composed of carbon compounds. Dehydration reactions: joining monomers to make polymer by taking out a water combination (-oh and h combine together to make h2o) Hydrolysis reactions: splitting polymer into monomers by breaking down water and adding (h+ and oh-) to individual monomer. Enzymes might be used to speed up hydrolysis. The monomers that are broken down can be assembles into new, different polymers that can perform specific functions required by the cell. Polymer: long molecule consisting of many similar or identical building blocks (monomers) linked by covalent bonds. Macromolecules carbohydrates, proteins, nucleic acids and lipids (not polymers). Each cell in our body has different macromolecules.
