Flashcards in CH 3 Exam 1 Proteins Deck (29):
Organic compound made up of amino acids?
Primary role of protein in the body?
Amino Acids are building blocks for proteins which contain?
and sometimes Sulfur
T/F a protein is large and made up of more than 100 amino acids
T/F Amino Acids are ESSENTIAL(Indispensable) Cant Synthesize, Must be get these from FOOD.
What is an essential amount of AA's needed?
T/F Amino Acids are NONESSENTIAL(dispensable) Synthesize in liver, or from diet.
What is a nonessential amount of AA's needed?
Good protein quality is needed for our bodies to make its complex parts. which are?
Foods that consist of all 9 essential amino acids in sufficient amounts and animal sources (e.g) fish, meat, eggs, cheese, milk and soy protein
Complete Protein (high-quality)
Lack one or more essential amino acids (e.g) plant proteins
Incomplete Protein (Low-quality)
Combining two foods (protein) in the same meal to compensate for deficiences in amino acid content. Use of whole grain is important.
T/F Functional Proteins regulates pH of the mouth
T/F Physiology of proteins is that digestion begins in the stomach
Recommended Dietary Intake RDI of protein depends on body size and physical activity. Estimated at?
What happens to the body when it is lacking protein?
lowered resistance to infecton
brittle & slow growing hair/nails
scaly skin w/ sores that wont heal
Two most worldwide Protein-energy Malnutrition (PEM) deficiencies are?
My plate recommends no more than how many oz of a protein rich food source or less per day?
If the body does contain more than 6oz needed the body has 2 choices which is? (Excess Protein)
use for energy
store it for fat
1) Acute Form
2) Severe protein deficiency
3) begins at 18mths to 2 years of age
4) Edema in legs, abdomen, face
5) child fails to grow and gain weight
6) delayed eruption & hypoplasia of teeth
"evil spirit infects the first child when second child is born"
1) Chronic form
2) Body's adaption to starvation
3)inadequate food intake(protein/calorie deficiency) over a long period time
4) skin and bones
5) Muscles and heart waste away and weakens
6) Common in children 6-18 months in impoverished nations
"to waste away"
What are building blocks for proteins?
T/F protein is vital for life and second only to water as the most important nutrient.
When two amino acids link together the resulting structure is called?
When three amino acids are linked its called?
When there are several hundred amino acids linked together, they form a?
In order for amino acids to join together, two hydrogen and one oxygen are dropped (water molecule) forming a bond?
A small amount of high quality protein added to a meal that is otherwise marginal in terms of protein quantity?
