Biochemical Substance & Biomolecules Flashcards
no life but biochemical interactions sustain life
Biochemical Substance
chemical substance in living organisms
Biochemical Substance
2 groups of biochemical substance
bioorganic and bioinorganic substances
substances that do not contain carbon
BIOINORGANIC
it includes water and inorganic salts
BIOINORGANIC
How many water constitutes the bioinorganic?
2/3 of human body mass
How many inorganic salts contains bioinorg subs?
4-5% of body mass
Substances that contain carbon
BIOORGANIC
maintain the balance of osmotic
pressures
Inorganic salts
includes carbohydrates, lipids,
proteins, and nucleic acids
BIOORGANIC
How many water constitutes the bioorganic?
1/4 of body mass
BIOINORGANIC SUBSTANCES
water (70%)
inorganic salts (5%)
BIOORGANIC SUBSTANCES
proteins (15%)
lipids (8%)
carbohydrates (2%)
nucleic acids (2%)
present in plant and animal cells
BIOMOLECULES
composition of the cell
50-95 % water
1% ions
organic molecules
carbon based molecules that are covalently bonded to itself or to H,O,N,S,P
ORGANIC MOLECULES
important organic molecule
HYDROCARBON
biomolecules derived form HC
HYDROCARBONS
2 broad types of biomolecules
SMALL BIOMOLECULES
MACROMOLECULES
Importance of Macromolecules:
a) Essential structures for the basis of life
b) Control and regulate this processes
c) Responsible for energy exchanges, irritability, metabolism, mobility and reproduction
4 MAJOR CLASSES OF SMALL BIOMO
Amino acids
Sugars
Fatty Acids
Nucleotides
Functions of small biomolecules
a. They are used to synthesize larger molecules like polymers (proteins, nucleic
acids)
b. Some have special biological functions (ATP – a nucleotide)
c. Involve in complex reaction pathways
hydrophobic; non polar and insoluble in H2O
HYDROCARBONS
biomolecules that is termed as primary molecules
SMALL BIOMOLECULES
