macromolecules and change
build and break down/manipulate the form to get something-proteins, carbs, nucleic acids...
working of body's physiology
chemical reactions break down and rebuild matter, creating and using energy
bone scan-radioactive tracer absorbed by bone
x-ray, x-ray darker(hot spot--over activity), x-ray lighter(cold spot--under activity), advantages
positively or negatively charge particle
+=feel good because it gave the electron; -=mean because it took the electron
polar covalent compounds
molecules joined together-unequal sharing of the electrons- hang out more towards one side of the atom
complex down to simpler pieces
heat is often a byproduct-energy released
high boiling pt. ability to absorb heat, high specific heat capacity
sweat-KE highest escape cooling the body
building blocks of more complex carbohydrates-repeating unit - simple sugars
stored form of glucose in simple sugar unis
liver and muscles
always 0.01% in blood
diabetes urine dip test-test glucose in urine- too much in blood - pick other energy source
uses of lipids in body
store energy for cellular activities,insulation, steroid hormones, support and structure = cholestrol
contains glycerol portion + 2 fatty acid chains
found hydrophobic and hydrophilic cellular structures found in membranes
non polar tails
fatty acid portion is insoluble in water
nonpolar = hydrophobic - is scared of water
all body cells:synthesize other steroids, estrogen, progesterone, testosterone =adrenal glands
saturated fats and cholesterol deposits in lining of blood vessels
lumin-->closing --> blood clot --> heart attack
