What are three ways that biochemists study biological organisms? - ANSWER-
among-the relationship between structure and function of biomolecules
-chemical reactions of organisms (metabolism)
-communication with and among organisms
What is biochemistry? - ANSWER-the chemistry of life
Molecular arrangements - ANSWER-linear= 180 degrees
trigonal planar= 120 degrees
trigonal pyramidal= 107.5 degrees
tetrahedral= 109.5 degrees
bent= 104.5 degrees
,How many of the 90 naturally occurring elements are found in living
organisms? - ANSWER-less than 30 (small nonmetal in upper right of the
table)
smaller vs larger element bonds - ANSWER-smaller elements are favored
because they can form stable covalent bonds (strong), the larger elements do
not form stable covalent bonds
What elements is critical to all living things and is found in large amounts? -
ANSWER-Carbon
Organic vs inorganic chemistry - ANSWER-organic-study of carbon based
compounds, inorganic- study of compounds typically not containing carbon
Carbon - ANSWER--has 4 valence electron permitting it to form 4 bonds
-forms long chains
-forms double and triple bonds
-forms ring compounds (cyclic compounds)
,forms bonds w many other atoms including H, N, and O
Alkanes - ANSWER-Straight chain compounds with only carbon and hydrogen
chemical and compounds formulas of the - ANSWER-methane= CH4, CH4
ethane= C2H6, CH3CH3
propane= C3H8, CH3CH2CH3
butane= C4H10, CH3CH2CH2CH3
pentane=C5H12, CH3CH2CH2CH2CH3
hexane=C6H14, CH3CH2CH2CH2CH2CH3
heptane=C7H16, CH3CH2CH2CH2CH2CH2CH3
*starting from CH4 add one carbon and two hydrogens in the chemical
formula and add one CH2 in each with CH3 on both ends
Four ways to draw organic molecules - ANSWER-chemical formula, condensed
formula, Kekule formula, and line bond formula
, Functional group - ANSWER-Specific arrangement of atoms in a compound
that define the chemistry of the molecule and control the properties of the
compound
Alkene - ANSWER-carbon-carbon double bond
Alkyne - ANSWER-carbon-carbon triple bond
Alcohol - ANSWER-R-OH
Aldehyde - ANSWER-CHO (double bond btwn C and O)
Amide - ANSWER-CNO (double bond btwn C and O)
Amine - ANSWER-R-NH2
Aromatic (benzene) - ANSWER-carbon ring with alternating double bonds
