Hello could you please answer this and also explain how you

Hello could you please answer this and also explain how you know which letter goes with each description?? It looks like this was 10 points and so I assume there should be a total of 10 letters in the blanks. Thank you!!

38. [10 pts.l Refer to the diagrams of 5 biomolecules (A-E) shown below. Match each biomolecule (by writing A, B, C, D biomolecule may be selected as an answer more than once.

Solution

Nucleotide contains sugar, phosphate and a nitrogen base either purine or pyrimidine. Molecules D and E are components of nucleotides.

Lipid is the common name given to the fats or oils. The lipids are a diverse family containing triglycerides, phospholipids and sterols. A triglyceride is a molecule containing three fatty acids bound to a glycerol molecule that serves as the back bone of the fatty acids. The best example of sterols is cholesterol. In cholesterol, each corner of the multi ring is positioned with a carbon atom. Molecules B and C are lipids.

Within the cells of the body the amino acids in the proteins are linked by a chemical bond called peptide bond. The peptide bond is formed between amino group of one amino acid and the carboxyl group of other amino acids. Through the formation of peptide bond the cells can synthesize poly peptides (peptide bond linking 10 or more amino acids). Biopolymer of protein is called polypeptide. Biopolymer of nucleotides is called nucleic acid (DNA or RNA) . Biopolymer of fatty acids is known as long chain fatty acids that may contain upto 20 or more carbons. Molecules A, C, D and E are components of biopolymers.

Hydrophobic core contains nonpolar molecules that repel with water surface. Fatty acids have nonpolar heads that are hydrophobic embedded in the core and the tails are hydrophilic located towards surface of membrane. Phospholipids have hydrophobic tails and hydrophilic phosphate head groups. Cholesterol is an amphipathic molecule that contain OH group towards membrane surface while remaining part embedded into hydrophobic core. Molecules B and C are part of hydrophobic core.
