Three components of amino acids - 🧠 ANSWER ✔✔anime group, acid
group, and side chain
How many essential amino acids exist? - 🧠 ANSWER ✔✔9
Why are adequate amounts of all essential amino acids required for protein
synthesis? - 🧠 ANSWER ✔✔- each amino acid codes fro something
different and your body needs to have all of them to make the proteins do
its work
- if any of these 9 essential amino acids are not present in sufficient
amounts in out died, protein synthesis will be stopped (limited amino acid)
Illustrate which factors differentiate proteins and the 7 roles of protein in the
body - 🧠 ANSWER ✔✔Sequence and shape differentiates the proteins.

,Seven roles of protein:
1. Supporting growth and maintenance
2. Building enzymes, hormones, and other compounds
3. Transport and reddit
recognition proteins
4. Building antibodies
5. Maintaining acid base balance
6. Maintaining fluid and electrolyte balance
7. Energy (and energy storage)
Factors that differentiate proteins: differences in amino acid sequences,
shape, some work `alone while others work together.
State the different paths an amino acid can take once it is in a cell - 🧠
ANSWER ✔✔- The amino acid can be used as is to build part of a growing
protein
- Make another needed compound, such as the vitamin niacin
- Make another type of amino acid

,- Convert to glucose and burned as energy or store as glycogen
- Convert to fat and burned for energy or stored in adipose tissue
Describe protein digestion and absorption from the mouth to the colon
(Figure 6-8). - 🧠 ANSWER ✔✔Stomach: acid denatures the protein strands
and an enzyme cleaves amino acids strands into polypeptides and a few
amino acids
Small intestine: enzymes from the pancreas and the intestine split peptide
strands into tripeptides, dipeptides and amino acids. The intestinal cells
absorb and transfer amino acids to the bloodstream
Bloodstream: transports amino acids to all the body's cells
Describe the purpose and how to conduct a nitrogen balance study - 🧠
ANSWER ✔✔Purpose: Compare nitrogen lost by excretion with nitrogen
eaten in food
How to conduct: measure daily nitrogen loss in urine, feces, sweat, and
skin under controlled conditions and then estimate the amount of protein
needed to replace those losses.
Define mutual supplementation and be able to recognize vegetarian meal
plans that contain complementary proteins - 🧠 ANSWER ✔✔Mutual

, supplementation: strategy of combining two incomplete protein sources so
that the amino acids in one food make up for those lacking in the other
food.
Example: legumes and grains
Marasmus - 🧠 ANSWER ✔✔chronic: severe deprivation of impaired
absorption of protein energy, vitamin deficiency in calorie intake
i. Develops slowly
ii. Severe weight loss/muscle wasting/fat loss
iii. Less than 2 years old
iv. Growth <60% weight for age
v. No edema
vi. No fatty liver
vii. Anxiety, apathy
viii. Hair sparse and thin
ix. Skin is dry, thin, and wrinkled
x. looks emaciated
Kwashiorkor - 🧠 ANSWER ✔✔acute: inadequate protein intake or infections
