Protein 2 Flashcards
What is protein essential for
growth and repair of cells,
the framework inside cells and body structures,
maintenance: enzymes, hormones and antibodies
What happens to protein the the body
Breaks down into amino acids
High biological value examples
Animal sources, meat, poultry, fish , eggs , dairy , soy
Low biological value examples
Vegetable sources, seeds, nuts, beans, grains, bread.
What is protein made from
Amino acids. 20 types. Contains 50- 10,000 amino acids
Essential amino acids
Cannot be made by the body must be supplied by eating, HBV foods contain all.
Non-essential amino acids
Can be made by the body, LBV foods have one or more amino acid missing.
The 9 essential amino acids
Histidine, Isoleucine, Leucine
Lysine,Methionine,Phenylalanine,Threonine,Tryptophan,Valine
7 nonessential amino acids
Arginine,Cysteine,Glutamine,Glycine,Proline,Serine,Tyrosine,
Protein amount from 1-3, 4-6, 7-10, 11-14, 15-18
1-3=15, 4-6=20, 7-10=28, 11-14=42, 15-18=55
Protein amount for 19-50 and 50+
19-50 = 55g
50+ =53g
Factors effect protein intake
Weight, age, health, job,
Too little protein symptoms
Shrinking of muscle tissue, oedema ( swell of stomach) slow growth, kwashiorkor(only in developing places)
Too much protein
Used as energy , cannot store protein
High protein diets health issues
Stain on liver and kidneys, heart function issues, bowel disorders
Complementary protein
Combining LBV foods to make up all nine Essential amino acids
