In a phospholipid, which components constitute the hydrophilic head? select the correct answer below: question 1 options: amino-alcohol modified phosphate, ester groups, and glycerol fatty acid and glycerol phosphate and fatty acid only the amino alcohol that modifies the phosphate group

Option (a) is the correct answer.

Explanation:

A lipid that contains a phosphate group in its molecule is known as a phospholipid.

These are the primary molecules present in a plasma membrane. These tend to contain two hydrophobic fatty acid tails and one hydrophilic head.

Hydrophilic means water loving in nature.

As phosphate group is a polar group due to this the hydrophilic region present in a phospholipid is able to interact with water.

In an amino-alcohol modified phosphate, ester groups, and glycerol, the glycerol is hydrophobic in nature. It also contains two fatty acids and a phosphoric acid which are present as ester. The polar head that mainly consists of phosphate group is hydrophilic and thus, it helps in combining to a water molecules.

Hence, we can conclude that in a phospholipid, amino-alcohol modified phosphate, ester groups, and glycerol are the components which constitute the hydrophilic head.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

it is the most commonly accepted one
