A total of _____ amino acids compose the majority of protein in living things and nine are _____ to human
Evgen [1.6K]

A total of <u>20</u> amino acids compose the majority of protein in living things and nine are <u>essential</u> to human.

  • All living organisms, from bacteria to people, depend on amino acids for survival.
  • The same 20 types of amino acids are present in all living things.
  • Only 21 amino acids are required by the human body to create all the proteins required for growth and function.
  • Your body can create thousands of different types of proteins with only the same 21 amino acids because they can be ordered in a wide variety of ways.
  • The body is unable to produce essential amino acids. They must therefore originate from food.
  • Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids.

olga55 [171]
Upon researching, I believe the choices are:

<span>A. Chest radiograph and pulmonary function tests
B. Complete blood count with differential
C. Ophthalmologic examination
D. Renal function tests
E. Thyroid function tests
</span>
Among these, the baseline tests necessary for the patient before taking the medication are: A. Chest radiograph and pulmonary function tests, C. Ophthalmologic examination, and E. Thyroid function tests. This is because Amiodarone has several possible toxic side effects. Some of these are thyroid toxicity, opthalmic effects, and pulmonary toxicity. Thus, it is necessary to first know the baseline of the patient for these systems and then checking if the results have deviated much after he/she takes the medication.
