Has an amino group and an carboxly group
A sequence of 3 nucleotide that form a unit of genetic code in DNA or RNa molecules.
The metabolic process by which the body expels excess nitrogen.
haveing four different groups attached to it.
h is the fr group and it is the only achiral amino acids
all amino acids in eurklaryotes like you and I are like you and I are L-amino aids. L for living.
Thus the aminogroup is drawn on the left for a fisher projection
This is the only L-amino acid with an R absolute configuration
non aromatic. can be a ring structure but cannot have alternating double bonds like the typical aromatic ring
kinky amino acid
forms a five-membered ring with the amino group
limited flexibility and which limits where it can appear in a protein
The ph at which half of the the molecules in a species is protonated and the other half is deprotonated
pH and pke relationship
when the ph is lower than the pKa the species tend to to be protanted for the majority
and vice versa
acid ionization constant
this measures the strength of an acid
catalytic triad found in chympotrypsin
having the characteristics of both an acid and a base
like a detergent:
has both hydrophobic and
amino acids in different pH environment
ionizable groups tend to be protonated in acid environment and deprotonated in basic environments.
thus low ph means that the ionizable group is protonated and at high pH it is deprotonated.
