Q

Triacyglycerols

A

the most abundant lipid category. They are the main components of animal (including human) fat, most of which is concentrated in adipose tissue; they are also the main components of vegetable oils. Because of this abundance, they constitute 90% to 95% of dietary fat

Q

valine

A

essential, non-polar
amino acid synthesized in plants. It is noteworthy in hemoglobin, for when it replaces
glutamic acid at position number six, it
causes hemoglobin to aggregate abnormally
under low oxygen
conditions, resulting
in sickle cell disease.

Q

Asparagine (Asn/N

A

is a non-essential
amino acid coded by AAU and AAC. Its carboxyamide in the R-group gives it polarity.

A

if the solute concentration is greater outside the cell than inside of it
then water will exit the cell and the cell will shrink
