PASS!!!
Where do we get amino acids - ANSWERS-From food and the breakdown of
cells; contributes to the amino acid pool
Synthesis process of proteins: - ANSWERS--synthesis of non protein
compounds that contain nitrogen, including creatinine and serotonin
-synthesis of body proteins such as enzymes, hormones, antibodies and
various components of cells
-synthesis of fat from amino acid carbon skeletons, this can be stored
through adipose tissue
-synthesis of glucose from amino acid carbon skeleton
What does the synthesis process of protein release? - ANSWERS-Nitrogen in
the form of free ammonia, used to synthesize urea in the liver, this is then
excreted as urine
Four levels of protein structure: - ANSWERS--primary structure: sequential
order of amino acids
-secondary structure: spiral structure due to chemical bonding between
amino acids
-tertiary and quarternary structure: further folding into a unique 3-D shape
that may be globular or fibrous
Proteins lose shape when subjected to: - ANSWERS-Heat, acids and bases,
heavy metals, alcohol
,What does protein denaturation result in? - ANSWERS-Loss in protein
function
Sickle cell anemia - ANSWERS-Red blood cells are crescent rather than disc
shaped; is the denaturation of proteins by changing one amino acid in the
chain
RDA for protein - ANSWERS-.8 g protein/kg of body weight/day
How much of daily intake should be from protein? - ANSWERS-10-35%
What groups of people are at risk for low protein intake? - ANSWERS-
distance runners, figure skaters, female gymnasts, wrestlers
Who are people that need more protein? - ANSWERS-children, adolescents,
pregnant or lactating women, athletes, vegetarians, vegans
Proteins - ANSWERS-large, complex molecules found in the cells of all living
things; critical components of all tissues in the human body
Protein functions - ANSWERS-Metabolism, immunity, fluid balance, nutrient
transport, can provide energy (4kcal/gram)
-Contain a special form of nitrogen that the body can use
Amino acids - ANSWERS-building blocks of proteins, each AA is attached
together by a peptide bond
Essential Amino Acids - ANSWERS-cannot be produced in body, must be
obtained by food, 9 out of 20 AA are essential
, Nonessential Amino Acids - ANSWERS-can be made by our bodies, also get
from diet
Transamination - ANSWERS-When one body converts one amino acid to the
other
2 AA-dipeptide
4-9 AA- oligopeptide
Complete protein - ANSWERS-Contains sufficient amounts of all 9 essential
amino acids; considered "high quality", mostly animal proteins exceptions
are soy, quinoa and chia
Incomplete protein - ANSWERS-does not contain all 9 essential amino acids
in sufficient qualities; growth and health are compromised because some
proteins cannot be synthesized; low quality, plant proteins, limiting amino
acids
Complementary proteins - ANSWERS-2 incomplete protein sources,
together supply all 9 essential amino acids {beans and rice}
Mutual Supplementation - ANSWERS-the act of combining complementary
proteins to make a complete protein
Protein functions: - ANSWERS--cell growth, repair and maintenance
-fluid and electrolyte balance
-pH balance
-energy source: by deamination
-transport and storage of nutrients
-compounds such as fribrin and collagen
