All proteins are sequences
of
Amino Acids
TERM 2
Proteins may contain ___ - ____ amino acids
DEFINITION 2
TERM 3
there are __ different amino acids- all with
different side chains.
DEFINITION 3
TERM 4
there __ essential amino
acids.
DEFINITION 4
TERM 5
What holds amino acids together?
DEFINITION 5
Peptide bonds
Amino acid sequence is determined by:
DNA
TERM 7
What are the functions of protein?
DEFINITION 7
sequence of amino determines shape(what someone looks
like) and shape of proteins determines function
TERM 8
Denaturing proteins means
DEFINITION 8
there is an unfolding of a proteins shape
TERM 9
What are some ways you can denature
proteins?
DEFINITION 9
by heat, alcohol, acids, bases, or salts
TERM 10
Structure/mechanical, Enzymes, Hormones,
Immune, Acid-Bases, Fluid balance,

DEFINITION 10
Are all functions of Protiens
Immune functions
proteins that attack bacteria and viruses
TERM 17
Fluid balance
DEFINITION 17
proteins function to attractfluid
TERM 18
Acid-bas balance
DEFINITION 18
proteins act as buffers
TERM 19
Transport
DEFINITION 19
Lipoproteins and other carrier molecules such as fats
(lipo=fats), Hemoglobin carries oxygen
TERM 20
Energy
DEFINITION 20
protein accounts for ~5-10% of daily calories
The first step of digestion
Acid in stomach denatures proteins
TERM 22
Step2 of digestion of proteins
DEFINITION 22
Enzymes (pepsin) in stomach breaks down peptide bonds to
form polypeptides
TERM 23
Step 3 of digestion of proteins
DEFINITION 23
pancreas and intestine release protein-digesting enzyme into
stomach which results in tripeptides, dipeptides, and amino
acids
TERM 24
Step 4 of digestion of proteins
DEFINITION 24
Enzymes on surface of small intestine split tripeptides/
dipeptides
TERM 25
Step 5 of absorption of
Proteins
DEFINITION 25
body absorbs and transfers amino acids to blood
The pH of the stomach is
1.5; acidic
TERM 32
The pH of small intestine is
DEFINITION 32
7.0; neutral

What enzyme breaks down peptide bonds?
DEFINITION 34
Pepsin
TERM 35
What are peptide bonds?
DEFINITION 35
bonds between amino acids
what are results of the protein-digestion
which occurs in the small intestine?
tripeptides, dipeptides, and amino acids
