Brief introduction
Proteins are complex
molecules made up of
C,H,Obut they also
contain N,S.
it is long chain
molecules made up of
smaller molecules
called amino acids .
proteins
Proteins
Proteins have 4 levels
Primary order of AA
Secondary folding chain of AA
Tertiary 3-D shape of protein
Quaternary multiple proteins combined
together

acid molecules

enzymes
Q3:Do you
Q1:What
know the
enzymes are? three type
Q2:How
that enzymes
enzymes
can be divided
by their's
work?
function?
gift!
Q4：Do you
know the 5
important
properties?
Soluble comment
proteins
There are more enzymes in our bodies
and more integrated ,our body will be
more healthy .
Human bodies and mammals contain
about 5000 kinds of enzymes .
Soluble comment proteins
—Only exist in the
blood of vertebrate .
—Exterminate the
pathogen .
—important part to
—metabolism ,growth
and reproduction
—transport oxygen
—make blood look
red
Insoluble proteins
make fibres
fibrous protein
found in skin and hair
Summary
 Proteins are vital
for growth and
repair of cells and
tissues as they
formimportant
components of cell
membranes.

Which one is not the main
physiological function of
proteins in human bodies?
A)transportation
B)immune(means use antibodies to
prevent something bad for us)
C)genetic
D)regulation
Genetic effect comes from the nucleic acid
rather than proteins.
Expand
Which one is the function
that proteins have but
sugar doesn't have?
A)control the matabolism
B)make up cell membrane
C)make up genetic material
D)the main energy for organism
Hormones is a kind of protein,and it can
control the matabolism but suger can't.

The relation of Protein
primary structure and its
function,which one is right?
A)the function must be different if protein
make up by different amino acid.
Use
Def.
of
protein
to
solve
B)the function of the protein will be more
this ifproblem.
similar
the protein primary structure
are more similar.
C)the same protein comes form different
organism,the primary structure is the
same.
D)all of them are wrong.
