Chapter3: The Chemical Basis of
Life II
Carbohydrates
Disaccharides
two monosaccharides joined by condensation and formed glycosidic bonds
Polysaccharides
many monosaccharides linked together to form long polymers.
Monosaccharides
simplest sugars each sugar molecule contains 5(pentoses) to 6(hexose) carbons
Lipids
steroids
Four interconnected rings of carbon atoms
Fats
saturated and unsaturated
phospholipids
are amphipathic molecules
waxes
Isomers
Structural isomers
Stereoisomers
Cis-trans isomers
positioning around double bond
Enantiomers
mirror image molecules
Proteins
Amino acid sequences, each amino acid consists of carbon atom in the centre and carboxyl group and amino group and functional group.
Tertiary structure
Secondry sturcture
Quaternary structure
Primary structure
Nucleic acids
DNA
Stores genetic information encoded in the sequence of nucleotide monomers, and has 2 strands
RNA
Decodes DNA into instructions to form a polypeptide chain, and RNA has one strand
Organic molecules and their formation
The organic molecule contains carbon atoms. Macromolecules formed from monomers by condensation while they break down into monomers by hydrolysis.
