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.

How would earth be different without photosynthesis?
Sunny_sXe [5.5K]
Without any photosynthesis, there would be no plants which would lead to the many of the civilians of Earth starving to death. In the likely scenario where photosynthesis does not occur the world would most likely go into an apocalyptic way with the human race as well as many other mammals dying. The organisms that would survive might be used as a food source but the population would drastically decrease
