What is the general structure of carbohydrates?
(CH2O)n
What do mono saccharides usually contain?
aldehyde group/ ketone group
True or false, glucose and ATP are mono saccharides
True
The general form of mono saccharides is?
Cyclic
Carbohydrates are attached to proteins are called ?
Glycoproteins
What are long chains of hydrocarbons with a polar carboxyl group at one end?
Fatty acids
What are fatty acids in which the fatty acid chains are joined to glycerol via ester linkages?
Triacylglcerols
What lipids have a polar head group and a hydrophobic tail?
Phospholipids
What are polycyclic hydrocarbons that form signaling molecules, components of membranes (cholesterol).
Steroids
Richer source of fuel, fatty acids or carbs?
fatty acids
Difference between saturated and unsaturated fatty acids?
double bonds
Glycolipids have blank head and blank tail
polar/hydrophobic
Steroids have a tetracyclic structure
true
what forces hold lipid bilayers together?
hydrophobic effects
What is Km
concentration for half maximal binding of substrate
What stops lipids from flipping to different sides of the lipid bi layer?
polar head
protein>sugar
glycoproteins
sugar>protein
proteoglycans
most common structure to cross lipid bi layer
alpha helix
proteins that pass through lipid bi layer
integral membrane
proteins binding to integral membrane proteins
peripheral membrane
proteins are anchored to the plasma membrane by virtue of their attachment to a fatty acid lipid that is embedded in the plasma membrane
membrane anchored proteins
Peripheral membrane proteins can be washed off of membranes with conditions like high salt
true
Integral membrane proteins can be removed with high salts
false
