Aldosterone is synthesized from cholesterol. <br> a. True<br> b. False
patriot [66]

Answer:

The correct answer is A. Effectively, aldosterone is synthesized from cholesterol.

Explanation:

Aldosterone is a steroid hormone from the mineralocorticoid family, synthesized in the glomerular area of the adrenal cortex of the adrenal gland. It acts in the conservation of sodium, in the secretion of potassium and in the increase of blood pressure. Its secretion is decreased in Addison's disease and increased in Conn's syndrome. Aldosterone, as well as all steroid hormones, is synthesized from cholesterol.

kotykmax [81]

Answer:

Explanation:

A protease is an enzyme that catalyzes the hydrolysis of the peptide bonds that tie polypeptide chains together, releasing individual amino acid subunits. The L and D nomenclature for amino acids defines the structure of the glyceraldehyde isomer through which the amino acid can be produced.

SEE BELOW FOR THE APPROPRIATE STRUCTURES.

We need to figure out why swine proteases hydrolyze L-amino acids but not D-amino acids in any way. we know that enzymatic catalysts act as polypeptides if you can recall. They must retain a very precise three-dimensional structure for a catalytic activity to occur. Substrates that do not quite match the required configuration at the active site will not be reacted to — this is a "lock and key" style.

The present exercise may be explained by the fact that the configuration and structure of D-amino acids prevent them from binding properly to the active site of the protease enzyme. Perhaps they're pointed in the wrong direction, or perhaps there happens to be missing electrical interaction that's needed to keep the substrate in position.

Nonetheless, L-amino acids, on the other hand, seem to have the right configurational aspects in the active site and are hydrolyzed.
