5.4 proteins- polypeptide Flashcards
what are polypeptides
polymers of proteins
what are monomers of proteins
amino acids
what are proteins made of
1+ polypeptides folded into a 3D structure
organic molecules possessing both carboxyl and amino groups:
amino acids
structure of amino acid
amino group + alpha carbon (an asymmetric carbon) + carboxyl group + R group (variable )
how to join amino acids into polymers
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
bond that joins proteins
peptide bond
how is a polypeptide formed
a polypeptide backbone is made and sticking out of these are the different appendages (R groups)
