Document Summary

We consume fats, proteins, and lipids to obtain energy. They are used as the building blocks for cellular growth and repair. Although all have the same formula, they are different due to the placement of the hydroxyl groups. Can contain an aldehyde group, or ketone group. Formation involves the loss of a h20 molec. Types of glyosidic bonds are specifically named by the carbons they are joining together. Dna & rna contain a sugar, nitrogenous base (a, g, c, t, u), and on or more phosphate groups. * way to remember: pyrimidine small molecule, long name vs. purine large molec, short name (opposites) Adjacent pairs of nucleotides are joined by phosphodiester bonds. Also involves the loss of a h20 molec. 2 strands of rna attached together, running anti parralel. Attached with base pairs (a&t, g&c - g&c are stronger bc there are.
