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
