What are the four macromolecules of life? Give examples and uses.
Carbohydrates – monosaccharides (glucose) --Storing short-term energy --Structural support – plants - cellulose Proteins – amino acids --structural materials (tendons, ligaments etc.) --help body's immune system to function effectively --specific carriers, including membrane transport proteins that move substances across cell membranes and through body --aid in muscle movement --are catalysts – speed up reactions (enzymes) *Protein function is determined by its shape *Denaturation of proteins results in loss of function? Lipids (“fats”) – glycerol and fatty acids --membranes --storing concentrated energy --insulate against cold Nucleic Acids – nucleotides (building blocks of DNA & RNA) --are polymers with ability to encode info (specifically to encode proteins) --sequence of nucleotides determines the sequence of amino acids along a polypeptide chain
