ANASTASIA PROTEINS
Proteins are involved in nearly every physiological process in the body. They function in
various capacities, including:
○ Transport Proteins: e.g. hemoglobinbin (transports oxygen), ferritin (transports iron)
○ Structural Proteins: e.g., elastin and collagen (support the body)
○ Contractile Proteins: e.g., actin and myosin (required for movement)
○ Enzymes: Catalyze numerous biochemical reactions
○ Hormones: Regulate various bodily functions
○ Receptors: e.g., proteins involved in nerve cell transmission
○ Transcription Factors: Regulate gene expression
These functions highlight the critical roles of dietary proteins in maintaining human health
and physiological processes.
AMINO ACIDS IN PROTEINS
- Number of amino acids: 20 standard aminos
- Structure: carbon atom linked to a hydrogen atom, amine group, carboxyl group and
an alkyl side chain
We need many enzymes to process these proteins in different ways.
NUTRITIONAL CLASSIFICATION
- Essential amino acids
- Non essential amino acids
- Conditionallly essential amino acids
Digestion:
If we break down these peptide bonds
we get shorter chains, during the
digestion we have a series of proteases
that we call peptidases. These
peptidases will catalyze the hydrolysis
of the peptide bond.
When we think about the digestive
system we start from the mouth…
In the mouth not a real digestion occurs
, we just have a mechanical process in
which with the chewing we are making
the food easier to be attacked later.
We are dropping the pH at about 2 or 3
(important) so we can kill the bacteria in
our food, and proteins will start to
denature and the peptide bond will
become more accessible to the
enzymes.
