AP Bio Ch 4-5
chapter 4 and 5
When there are no double bonds between the carbon in the chains, allowing as many hydrogen atoms as possible
unsaturated fatty acid
When three fatty acid molecules each join to glycerol by an ester linkage
Macromolecules, serve as storage material
Macromolecules that exist as polymers
A polymer of glucose that is like amylopectin but more excessively branched
polymers of amino acids
A large molecule consisting of thousands of covalently connected atoms
A six-membered ring of carbon and nitrogen atoms
A bond between a hydroxyl group and a carboxyl group
→ a delicate coil held together by hydrogen bonding between every fourth amino acid.
three-dimensional biological polymer constructed from a set of 20 different monomers called amino acids
This is an organic sulfur compound that contains a sulfur-hydrogen bond ( S-H).
a polymer consisting of many nucleotide monomers; serves as a blueprint for proteins and, through the actions of proteins, for all cellular activities. Two types are DNA & RNA
a type of weak chemical bond formed when molecules that don't mix with water come together to exclude the water
organic compounds and functional groups that contain a basic nitrogen atom with a lone pair.
long carbon chain carboxylic acid; vary in length & in the # and location of double bonds;
A protein may undergo reversible structural changes in performing its biological function. The alternative structures of the same protein are referred to as conformation.
→ strong covalent bond formed when the sulfur of one cysteine monomer bonds to the sulfur of another cysteine monomer.
a polymer of amino acids
compounds containing a carboxyl group; aka organic acids because they tend to dissociate to release H+
the unique, genetically coded sequence of amino acids within a protein
macromolecules consisting of one or more polypeptide chains folded into a unique 3D shape/conformation
→compound with an amino group that can act as a base; the nitrogen, with its pair of unshared electrons, can attract a hydrogen ion, becoming --NH3+.
