Chapter 3: Chemical Basis of Life
proteins
the buildings blocks are amino acids
amino acids are held together by peptide bonds
four types of structures
lipids
consist of steroids, triglycerides and phospholipids
carbon
It is the base of all organic molecules
Its structure
the atomic mass is 6
the atomic number in the periodic table is 12
Four valence electrons
Covalent bond (four single bond result in tetrahedral shape)
Carbohydrate
polysaccharide
several monosaccharides bound together
example:
monosaccharide
simplest type of sugars like glucose and fructose
disaccharides
consist of two monosaccharides bound together
example: sucrose and lactose
Nucleic acid
DNA
double helix strand
ACGT
RNA
ACGU
single helix strand
organic molecules
functional group:
hydroxyl
carbonyl
methyl
amine
phosphate
carboxyl
IMPORTANCE
Environmental results (carbon footprint)
Biological results (photosynthesis and cellular respiration)
