amino acids and proteins
proteins incipit
large, complex molecules
100 amino residues
proteins
depending chemical composition
simple proteins
conjugated proteins
many critical roles in body
polymers = 20 amino acids
range size small
5733 daltons
51 amino acids
structure of amino acids
incipit
alpha crabon
optical isomers
D/L-amino acid
asymetrical
bonded to 4 groups of atoms
isoeletric point
pH-->amino acids=net charge of 0
every amino acids different isoeletric point
R group
determining three-dimensional structure/function protein
classification side chain
amino acid with polar side chains
amino acid with non-polar side chain
amino acid with charged side chain
special cases
amphometric behaviour
can act both acids and bases
dipolar ions
carbozyl+amino groups = izoned
amino acids
carboxyl functional group
amino functional group
R group attached to alpha carbon
glycine
non-optical/essential amino acids
proteins contains small quantities glycine
1 hydrogen atom
proline
ring structure = limits flexibility
found = protein bends or loops
modified amino group
lacks hydrogen
instaed forms a covalent bond + hydrocarbon side chain
cysteine
-SH group = disulfide bond
determine how polypeptide chain folds
synthesized by human body
important source = sulfide human metabolism
pepite linkages
carboxyl group (1 amino acids) react another amino group
