Document Summary
Most common trace elements: mn, fe, co, cu, zn. Less common trace elements: v, cr, mo, ni, ga, b, al, si, f, as, se, sn, i. Only about 30 of the 90+ naturally occurring chemical elements are essential to the human body. Iron imbalance: too much = hemochromatosis (cancer of liver); too little = anemia (low lvl of healthy red blood cell or hemoglobin) Hydrocarbon: organic compounds composed of only c and h. varies in length, branch vs. unbranched, types of bonds, can be arranged in rings. Ex: gasoline is mixture of large hydrocarbons; ethane; propane. Large hydrocarbons constitute skeletons of fatty acids in food (french fries) Aromatic compound: hydrocarbons or hydrocarbon derivatives containing benzene rings (unsaturated) Functional groups: a group of specifically linked atoms with characteristic physical and chemical properties. Aromatic compounds: number starts with first side group. Alkyl group: alkane with one h atom removed (ex: methyl-)
