(34 cards)
Which organic macromolecule is NOT composed of monomers & insoluble in water?
Lipids
What are the 4 organic macromolecules?
Lipids, carbohydrates, proteins & nucleic acids
Define Hydrophilic.
Likes water
Define hydrophobic
Hates water
What are the 4 groups of lipids?
Fats, phospholipids, waxes & steroids
Fats are composed of what?
3 fatty acids & a glycerol; dehydration synthesis
Fats are also known as
Triglycerides
Saturated fats are composed of
A single bond between carbon atoms
Unsaturated fats are composed of
A double bond between adjacent carbon atoms
Polyunsaturated fats are composed of
Several double bond between carbon atoms
What are the 3 types of fats?
Saturated, unsaturated, polyunsaturated
Phospholipids contains what & describe the structures
2 acid tails; head-hydrophilic & tail-hydrophobic
When the head & tail of the phospholipid come together they create
Membranes
Waxes are composed of
A long chain fatty acid link covalently to a long chain alcohol by an Ester bond
Waxes are used to
Store energy & are insoluble in water
Steroids are composed of
4 carbon rings fused together & attaches to various side chains/groups
What are the steroids roles in metabolism
Acts as hormones
What functional group are sterols & the purpose of sterols
Hydroxyl group; keep cell membranes fluid and functional
Carbohydrates are composed of
Carbon, oxygen and hydrogen
What are three types of carbs?
Monosaccharides, disaccharides, polysaccharides
What is a monosaccharide?
Simplest carbohydrate and simplest sugar
What is a disaccharide?
Linkage of 2 monosaccharides via dehydration synthesis
What is a polysaccharide?
Linkages of multiple monosaccharides
What is the purpose of nucleic acids?
Information storage devices for DNA and RNA
