B1.1.3 Amino Acids and Proteins Flashcards
proteins are polymers of
amino acids
how many types of amino acid are there?
20
what are the differences between the amino acids
the R chain varies
identify this level of protein structure
primary
identify this level of protein structure
seconday
identify this level of protein structure
teritiay
identify this level of protein structure
quaternary
the order of amino acids in a polypeptide is the
primary structure
Alpha Helices and Beta pleated sheets are present in the
secondary structure
further folding and bonding occurs in the
tertiary structure
additional polypeptide chains may be added in the
quaternary structure
bonding within a protein affects it
3D structure and therefore its function
what function do fibrous proteins have
structural
what functions do globular proteins have
metabolic
give an example of a fibrous protein
keratin
what type of bond is represented by A
ionic bond
what type of bond is represented by B
Hydrophobic interaction
what type of bond is represented by C
disulphide bond
what type of bond is represented by D
hydrogen bond
this type of protein diagram is a
ribon diagram
