Is the phosphate group attracted to water (hydrophilic) or is it repelled by water (hydrophobic)

Biology
1 answer:
Finger [1]3 years ago
6 0

Answer: The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic. Since the heads are hydrophilic, they face outward and are attracted to the intracellular and extracellular fluid.

LenKa [72]

Answer:

Hydrolysis

Explanation:

Hydrolysis is a reaction that needs water to breakdown macromolecules into simpler units.

Macromolecules are giant polymers made up of several repeating monomeric units.

  • These units are too complex for the body to digest and derive nutritional benefits from them.
  • During hydrolysis, the complex is broken down into monomers.
  • The monomeric units are absorbable and useful for the body.

Fat consist of a molecule called glycerol that is attached to one, two, or three fatty acids. Glycerol is the basis of all fats and consists of a three-carbon chain that is attached to the fatty acids.

2. Fatty acids

Fats is made up of three fatty acids and a glycerol, it can also be called triacylglycerols or triglycerides.

3. Monoglyceride

It is a glycerol molecule with a singular fatty acid. It is formed through the combination of OH of glycerol to the OH of the fatty acid.

4. Triglycerides

It has three fatty acid molecules. It is a tri-esters made up of a glycerol attached to three fatty acid molecules.

5. Hydrocarbon

Fatty acids is made up of long, unbranched hydrocarbons with a carboxylic acid group found at one end.

6. Hydrophobic

The hydrophobic nature of fat arises from the carbon-hydrogen bonds that are nonpolar.
