Both glycerophospholipids and sphingolipid structures are asymmetrically distributed in the two layers of the phospholipid bilayer. Sphingolipids are membrane lipids that have a ceramide backbone while glycerophospholipid has glycerol present in its membrane lipids. Sphingolipids may or may not be present.

In cells there are two classes of phospholipids, glycerophospholipids and sphingophospholipids.

Glycerophospholipids have two fatty acids attached to a glycerol molecule, since the third hydroxyl group of this alcohol is esterified with a phosphate, in turn attached to a second alcohol. The combination of glycerol with two fatty acids and phosphate results in a molecule called phosphatidic acid, which forms the basic structure of glycerophospholipids.

Sphingophospholipids contain ceramide, which is a molecule formed by the union of two fatty acids with a serine (which replaces the glycerol present in glycerophospholipids). The union of a serine with one of the fatty acids forms the amino alcohol called sphingosine or sphingol. Serine is formed by the aggregation of a fatty acid with sphingosine. The sphingophospholipid in the cells is sphingomyelin, originated from the union of ceramide with phosphorylcholine.

Despite the differences. both exhibit two large non-polar hydrophobic tails (two fatty acids) and a polar hydrophilic head comprising glycerol, phosphate and the second alcohol. For such characteristics phospholipids are amphipathic molecules.

Rudik [331]

Answer: Rheumatoid arthritis

Explanation:

Rheumatoid arthritis is a disease which is a autoimmune disease which is usually associated with the pain and inflammation in the joints. This is the condition in which the person is not able to walk or sit for a longer period of time as it is painful.

The lysosomes is an enzyme that is found in the saliva and tears of human beings which helps in the degradation of the cell wall.

In case of autoimmune diseases the antibody present in the body destroys the cells of the body considering it as self antigen. Its concentration is found high in the people suffering from this autoimmune disorder.

This is because mutations not only help a species survive in certain conditions, but also allows diversity within a population. For instance, a bug species can develop a mutation to bug spray, allowing it to survive through its prey or killers. Therefore, ultimately benefiting and helping the species.
