In a phospholipid, which components constitute the hydrophilic head? Select the correct answer below: Question 1 options: amino-
KIM [24]

Answer: 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.

What is the molar mass of barium hydroxide
maksim [4K]

Answer:

171.34 g/mol

Explanation:

Ba molar mass = 137.328 g/mol

O molar mass = 15.999 g/mol * 2 = 31.9980 g/mol

H molar mass = 1.008 g/mol * 2 = 2.0160 g/mol

137.328 + 31.9980 + 2.0160 = 171.3420 = 171.34 g/mol
