Transcript of proteins

fundamental for living organisms






large biological molecules/ macromolecules






3-dimensional
structure

where do we find proteins?









red meet
(Beef)
white meet
(poultry)
eggs
fish
Legumes/seeds
proteins
20 different types








100 to 1000
determines its
activity.
nucleotide sequence
proteins in our cells






how eating proteins helps our body










a




FUNCTIONS
different kinds of proteins:
-catalyzing metabolic
reactions.
-replicating DNA.
-responding to stimuli.
-transporting molecules from one location to another
-lowers -cholesterol
-chills
-hot flashes
-prevents breast and prostate cancer
-aids weight loss
-wards off osteoporosis

30 % to 50 % lower risk of :
-myocardial infarction
-sudden cardiac death
-cardiovascular disease
-heart attacks
EATING NUTS SEVERAL TIMES A WEEK:

how eating proteins damage our body





bodybuilders
high-protein diet (200 to 400 g/d)
very high protein and fat intake +
very low carbohydrate intake=
DAMAGE TO THE BODY
to increase muscle mass
EATING SOY-BASED FOODS:
what would happen without proteins






(Better Health Channel; www.betterhealth.vic.gov.au)
NO ENZYMES
=molecules do not get in and out the cells
=no/lower reactions (ES: digestion)
MEMBRANE and TRANSMEMBRANE
transport molecules
PROTEINS
form much of our cellular structure.
ACTIN and MYOSIN
build muscles and allow movement.
TUBLIN
is part of the cytoskeleton.
NO ANTIBODIES
=no/weaker immune response

composed of one or more chains of amino acids

interesting facts





1) Fish is a very important part of a healthy diet:
-eating fish or taking fish oil is good for the
heart and blood vessels.
-eating one to two servings of fatty fish a week—reduces the risk of dying from heart disease by 36%
2) -COMPLETE PROTEINS: (animals)
contain all the amino acids needed
to build new proteins.
-INCOMPLETE PROTEINS: (fruits, vegetables, grains, nuts) contain only the "essential" amino acids (=amino acids that the body can’t make from scratch or create by modifying another amino acid)
