Document Summary

Macromolecules: macromolecules, proteins: chains of amino acids. Each protein is composed of a unique sequence of different amino acids and a different size and structure from the rest: the arrangement of the amino acids in the chain determines. Form complex structures capable of many functions including: structural components of cells, catalysis of reactions, communication processes. Myglobin: example of a protein that stores o2 in muscle tissue: molecular mass of 16 500 g/mol. Protein molecules have molar masses between 10 000 and 100. 000 g/mol: because macros are so large, we use kda (kilodaltons, 1 dalton= 1 g/mol. Largest single protein molecule is titin with 10,000 kda. Amide bonds link amino acids: nucleic acids: made as chains of nucleotides. Different bases are attacged giving nucleic acids unique and characteristic sequences. Nucleotide: repeating unit, base + sugar + phosphate. Ester bonds link sugars to phosphate: polysaccharides: chains of simple sugars. Simple repetitive structures of one or two sugars, with no definite size.
