Enzymes
are proteins that act biological catalysts
Substrates
are the molecules on which an enzyme acts
Active Sites
are the place on the enzymes that the substrates bond
pleated sheet protein
arranged side by side
negatively charged
aspartate, glutamate
Aromatic
benzene ring
Proteins can form different shapes
chain, helix, pleated sheets, and irregular
Proline
forms a cyclic ring it can cause kinks to occur in the protein structure
Cysteine
has a reactive sulfur-containing thiol group that can form disulfide bonds disulfide bonds are broken by chemical treatments
polar amino acid
have a hydrophilic side chain
non-polar amino acid
have a hydrophobic side chain
electrically charged amino acids
help stabilize the protein's structure and mediate protein-chain interactions
positively charged
histidine, arginine, lysine
Enzymes ____ the rates of chemical reactions in living things
increases
non-polar is located on the _____ of the protein structure
interior
Peptide
is any combination of amino acids in which the amino group of one amino acid is bonded to the carboxyl group of another amino acid
helix protein
may coil into a regular spiral
basic
means high ph
acidic
means low ph
Coenzymes
need nonprotein to assist transformation
