Protein Flashcards
Composed of C, H, O, and N.
PROTEINS
Basic building block of proteins
AMINO ACIDS
End product of protein digestion
AMINO ACIDS
before being absorbed in the body, proteins must be?
broken down into amino
acids before it is absorbed by the body.
In adult, what is the total percentage of protein in body weight?
20% of total body weight.
how many proteins should be total calories per meal?
10% - 35% of total calories per meal
Major structural and functional components of every living cell.
PROTEINS
Every tissue and fluid in the body contains some protein except?
bile and urine.
Basic building blocks of protein and end product of protein digestion.
AMINO ACIDS
how many Amino Acids do we have?
20 Amino Acids
what amino acid does body cannot make
them so they must be supplied through diet.?
9 essential or indispensable –
what amino acid in which cells make
them as needed through the process of
transamination.
11 nonessential or dispensable
– found in milk; helps an individual sleep at night.
Tryptophan
amino acids for nerve cells
Histidine
amino acids that are adrenaline-like, vasoconstricts; helps in CNS
Phenylalanine
9 Essential or Indispensable
Histidine Isoleucine Leucine Lysine Methionine Phenylalanine Threonine Tryptophan Valine
FUNCTIONS OF PROTEINS
- Body structure and framework
- Enzymes
- Other body secretions and fluids
- Fluid balance
- Acid – base balance
- Transport molecules.
- Other Compounds
- Some amino acids have specific functions within the body.
- Fueling the body.
how many amino acids are found in skeletal muscle?
40%
how many amino acids are found in skin and blood?
15%
Protein that facilitate what?
specific chemical reactions in the
body without changing themselves.
give example of enzymes break down larger molecules into smaller ones.
Eg. Digestive Enzymes
give example of enzymes that combine molecules to form larger compounds.
Enzymes involved in protein synthesis in which
amino acids are combined.
Amino acids also make:
o Neurotransmitters
§ Serotonin – responsible for moods.
§ Acetylcholine –– related to
parasympathetic NS.
• Contracts smooth muscle.
o Antibodies
o Some hormones
§ Insulin
§ Thyroxine
§ Epinephrine – adrenaline
o Breast milk
o Mucus
o Sperm
o Histaminewhat maintain the proper balance of fluid among the
intravascular, intracellular, and interstitial
compartments of the body?
Albumin
