Phospholipids can spontaneously form a bilayer in our
bodies and creates our…
Cell membranes
Lipids, 300
What are the two polymers of nucleic acids?
RNA & DNA
Nuc. Acids, 300
Sugars and complex carbs are stored as what
polysaccharide in animals?
Glycogen
Carbs, 400
Explain each step in protein folding including
quaternary.
Primary: peptide bonds make an
amino acid chain
Secondary: hydrogen bonds create
alpha helix & beta pleated sheets
Tertiary: hydrophobic/hydrophilic
create 3D protein
Quaternary: multiple subunits
Proteins, 400
What is the main function of steroids in the body?
Hormones – cell
maintenence
Lipids, 400
What are the three parts to a nucleotide?
5 carbon sugar
Phosphorous group
Nitrogenous base
Nuc. Acids, 400
Which monosaccharide is repeated over and over in a
starch molecule?
Glucose
Carbs, 500
What is denaturation?
The conformational
change of an enzyme
due to change in temp
or pH
Proteins, 500
What is the chemical and physical difference between
saturated and unsaturated fats?
Saturated: single bonds, comes
From animals, solid at room temp
Unsaturated: at least one double
Bond, usually from plants, soft or
Liquid at room temp
Lipids, 500
What is the difference between RNA and DNA?
RNA: Ribose sugar
DNA: Deoxyribose sugar
