Question

The Specific gravity of lipids is
A. 1.5
B. 1.0
C. 0.8
D. 0.2

Answer 1

Hint:
Before we proceed to the solution it is essential to know about the definitions of lipids
A large class of naturally occurring compounds known as lipids comprises fats, waxes, sterols, monoglycerides, diglycerides, phospholipids, and fat-soluble vitamins (such as vitamins A, D, E, and K). Carbon, hydrogen, and oxygen are the same elements found in lipids as they are in carbohydrates (C, H, and O). However, lipids have fewer polar hydroxyl groups and are mostly composed of hydrocarbon chains (or rings) (-OH). Due to this, most lipid molecules are nonpolar hydrophobic compounds (they do not dissolve well in water).

Complete step by step answer:
The lipid's refractive index and specific gravity were discovered to be 0.93 at 30 °C and 1.467 at 31.5 °C, respectively.
The lipid's respective saponification value, equivalent saponification value, iodine value, peroxide value, and acetyl value were discovered to be 220.325, 254.624, 96.05, 1.993, and 11.32.
Small molecules that are hydrophobic or amphiphilic can be widely referred to as lipids. Due to their amphiphilic nature, some lipids can form vesicles, multilamellar or uniflagellar liposomes, or membranes in an aqueous environment.
Therefore, the specific gravity of lipids is 0.8

Option ‘C’ is correct

Note:
Lipids have a variety of roles in the body, including energy storage, signalling, and serving as structural elements of cell membranes.
Nanotechnology, the cosmetic and food sectors, and the food industry use lipids.
Ketoacyl and isoprene groups, two different biochemical "building blocks," are the sources of all or a portion of biological lipids. This method allows for the division of lipids into eight groups: sphingolipids, saccharolipids, glycerophospholipids, and fatty acyls.
