Document Summary

Acidic solutions low ph and high h+ concentration. Cells have molecules within them buffers prevent ph from changing so quickly. Four main types: carbohydrates, proteins, nucleic acids, lipids. Functional groups give them certain properties to find if they"re functional. Carbon-hydrogen bonds tend to be non-polar and neutral: don"t dissolve well. Tiny building blocks to make polymer, stick together to make it longer. Function/role: carbohydrates, source of energy, helps cell communicate with another, proteins, help developing muscle, do most of the work, nucleic acids. Inside dna, rna: genetic info, lipids, cholesterol, hormone, testosterone, estrogen, long term energy store, to store more energy fat weighs less. Dehydration synthesis binds two monosaccharides forms disaccharide. Starch: energy: enzymes help break apart starch, easily digests starch but not cellulose. Each nucleotide has four types: acgt dna, acgu rna. Five types: adenine, cytosine, guanine, thymine and uracil. Dehydration and hydrolysis happen the same exact way: sugar phosphate flow.
