5.4 proteins- polypeptide Flashcards
1
Q
what are polypeptides
A
polymers of proteins
2
Q
what are monomers of proteins
A
amino acids
3
Q
what are proteins made of
A
1+ polypeptides folded into a 3D structure
4
Q
organic molecules possessing both carboxyl and amino groups:
A
amino acids
5
Q
structure of amino acid
A
amino group + alpha carbon (an asymmetric carbon) + carboxyl group + R group (variable )
6
Q
how to join amino acids into polymers
A
when the amino group of one and the carboxyl group of another are adjacent, they can be joined by a dehydration reaction forming a peptide bond
7
Q
bond that joins proteins
A
peptide bond
8
Q
how is a polypeptide formed
A
a polypeptide backbone is made and sticking out of these are the different appendages (R groups)
