Answer:

Within the past 50 years, there has been a significant temperature increase on the Earth. Our world is getting dangerously warmer. Is it because of global warming? Some people, the climate change doubters, say there is no such thing. However, if you look at all the facts, you can clearly see that the temperature is rising. Humans are the reason for global warming and the temperature increase of the world.

Match each lipid with its correct components or description.

Mumz [18]

Answer:

(1) glycerophospholipids ⟶ (C) lipids with phosphate-containing head groups

(2) cerebrosides ⟶ (D) fatty acid linked through an amide bond to the sphingosine C(2)-amine

(3) gangliosides ⟶ (B) anionic sphingolipids containing one or more sialic acid residues

(4) sphingolipids ⟶ (A) built on sphingosine

Explanation:

1) Choline (Fig. 1) is a glycerophospholipid. It is a glycerol-based lipid with a phosphate-containing head group.

(2) Galactosylceramide (Fig. 2) is a cerebroside. It contains a fatty acid linked through an amide bond to the sphingosine C(2)-amine

(3) Gangliosides are glycosphingolipids that contain sialic acid. GQ1b (Fig. 3) is one of the most abundant gangliosides in the human brain. The carboxyl group of the sialic acid is in the ionic form.

(4) Sphingomyelin (Fig. 4) is a sphingolipid. It is based on sphingosine, with a phosphocholine head and a fatty acid chain.
