BLG 10A/B Lecture Notes - Lecture 2: Galactose, Thymine, Uracil
Document Summary
Part 2: biochemistry, study of chemical composition and reactions of living matter all chemicals are either organic or inorganic. Major elements of the body: carbon (c), hydrogen (h), oxygen (o), nitrogen (n) = about 96% of body mass. 2. 6: inorganic compounds: (most) do not contain carbon: water, salts, and many acids and bases. Acids and bases, electrolytes; ionize and dissociate in water. Acids, proton donors release h+ (hydrogen ions = naked proton) e. g. hcl (cid:314) h+ + cl- important acids: hcl (hydrochloric acid), hc2h3o2 (acetic acid, or. Hac - acidic part of vinegar) and h2co3 (carbonic acid) Bases, proton acceptors accept h+ e. g. naoh (cid:314) na+ + oh- and then oh- + h+ (cid:314) h2o important bases: bicarbonate ion (hco3. Common waste product of protein breakdown in body. 2. 5: chemical equations, occur when chemical bonds are formed, rearranged, or broken reaction written in form of chemical equation (cid:314) reactant(s) (cid:314) product(s) (cid:314) ratio (coefficient(s))
