Answer:

A) The hydroxide ion concentration in the solution would be greater than that in pure water.

Explanation:

Spermine has four amino groups. In water, these amino groups will be protonate -In NH₂⁺ or NH₃⁺- decreasing the H⁺ concentration and, by water equilibrium, increasing OH⁻ concentration.

Thus, in an aqueous solution of spermine <em>the hydroxide ion concentration in the solution would be greater than that in pure water.</em>

I hope it helps!

Answer:

The correct answer is option A)  The hydroxide ion concentration in the solution would be greater than that in pure water.

Explanation:

Spermine is basic in nature as it contains di-amine group (NH2), which is basic in nature that is, it easily gives off electrons.

Thus being basic spermine solution will have more concentration of Hydroxide ion [OH-].

What is the reaction used to join the fatty acid to the glycerol molecule?
m_a_m_a [10]

Answer:

The reaction that is used to join fatty acid and glycerol is known as Lipogenesis.

Explanation:

Lipogenesis is an important anabolic pathway that helps in the biosynthesis of triacylglycerol by joining glycerol with fatty acid by ester linkage.Lipogenesis occur in liver and adipose tissue .

             Lipogenesis takes place in our body to store excess fatty acid in form of triacylglycerol which is a complex lipid molecule.
