Fast Facts: Lipids

  • A lipid is any biological molecule that is soluble in nonpolar solvents.
  • Lipids include fats, waxes, fat-soluble vitamins, sterols, and glycerides.
  • Biological functions of lipids include energy storage, cell membrane structural components, and signaling

There are many different types of lipids. Examples of common lipids include butter, vegetable oil, cholesterol and other steroids, waxes, phospholipids, and fat-soluble vitamins. The common characteristic of all of these compounds is that they are essentially insoluble in water yet soluble in one or more organic solvents.

USF The chromosomes of the species known as Vulcans together contain 24% adenine. Apply Chargaff’s rules to calculate the percen
Gwar [14]

Answer:

Thymine = 26%,

Adenine = 26%

Guanine = 24%

Cytosine = 24%

Explanation:  

Chargaff's stated that the DNA of any cell has the same content of purine (A and G) and pyrimidine (T and C) bases. In the DNA molecule, T pairs with A (T–A), and G pairs with C (G–C). In consequence, according to this base pair-rule, the amount of Thymine (T) should be equal to the Adenine (A), and the amount of Cytocine (C) should be equal to the Guanine (G).

In this example, the content of A is 26%, and thereby the amount of the remaining bases is: 48 % (26 + 26 = 52 >> 100 - 52 = 48), where C= 24% and G=24%.
