Explanation / Answer

Composed of fatty acids and phosphoric acid and a nitrogenous base; an important constituent of membranes

Sphingolipids are Similar to phospholipids in a polar head group and two non polar tails.

Fatty acid 24:0 is a saturated fatty acid with 24 carbon chain. Found in natural fats. It is a byproduct of lignin.

Fatty acid 20:0 is a saturated fatty acid with 20 carbon chain butter, peanut oil and corn oil.

Phospholipids are a class of lipids containing a phosphate group in its molecule.

Fatty Acid is saturated or unsaturated carboxylic acid with aliphatic chain.

Cholesterol is a sterol occurs in animal cells an important constituent of cell membrane precursor.

Estrogen is a steroid hormone an important female sexual hormone produced by ovaries.

Sodium Dodecyl Sulfate is an important anionic surfactant known to denature proteins. It is used in denaturing Polyacrylamide gel Electrophorosis for the determination of protein molecular weight.

Triton x-100 an anionic surfactant for most immune precipitation experiments.

Gel filtration Chromatography also called as size-exclusion chromatography to separate soluble macromolecules and smaller molecules. Such as proteins, peptides, and oligonucleotides based on their size.

Affinity chromatography is a biochemical technique for purification of a specific molecule from complex of mixture based on the specific binding interaction between an immobilized ligand and its binding partner.

Enthalpy is the amount of energy in a system capable of doing mechanical work

Entropy is a thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work

EQ is a measure of emotional intelligence, or your ability to use both your emotional and cognitive skills in your life.

Micelles are lipid molecules arranged in a spherical form in aqueous solutions. They occur in a bilayer in cell membrane.

Peripheral membrane proteins have weaker and temporary connections to the membrane.

Integral proteins are permanently connected to the cell membrane and embedded in the hydrophobic layer of the membrane.

The transport epithelial cells in the ascending loop of henle are
