Which is a component of a phospholipid? carbon ring hydrophilic head long-chain alcohol amino acid

Ans.

Phospholipids can be defined as lipid derivatives, having two hydrophobic tails of fatty acids and a hydrophilic or polar head of phosphate group. As they have both polar and non-polar groups, they are amphiphilic in nature

Phospholipids form lipid bilayers, in which polar head groups point outward and non-polar or hydrophobic tails are present at the interior of bilayer.

Thus, the correct answer is option). 'hydrophilic head.'

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
