A condensation reaction occurs when two monosaccharide units are joined together to form a disaccharide. In the process, a water molecule is produced and lost.
The OH group of each monosaccharide are the ones that get joined to each other, with the removal of H2O. A disaccharide containing an -O- bridge between the two monosaccharides is formed.
Between glucose units, these bonds are usually between carbon 1 of one glucose molecule and carbon 4 or 6 on the other. Depending on the direction of the OH group at carbon 1, the link may be called an alpha or a beta linkage.
Answer: 4.32g
Explanation:
MM of H2 = 1 x 2 = 2g/mol
2g of H2 contains 6.02x10^23 atoms.
Therefore Xg of H2 will contain 1.3 x 1024 atoms i.e
Xg of H2 = (2 x 1.3 x 1024) / 6.02x10^23 = 4.32g
The PH scale ranges from 0-14, 7 is neutral. The acids would be 0-6, and bases 8-14
Answer:
We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the <u>phosphate</u> group attached to the 5' carbon atom of the sugar portion of a nucleotide and the <u>hydroxyl</u> group attached to the <u>3'</u> carbon atom
Explanation:
Nucleic acids are polymers formed by a phosphate group, a sugar (ribose in RNA and deoxyribose in DNA) and a nitrogenous base. In the chain, the phosphate groups are linked to the 5'-carbon and 3'-carbon of the ribose (or deoxyribose) and the nitrogenous base is linked to the 2-carbon. Based on this structure, the nucleic acid chain orientation is identified as the 5'-end (the free phosphate group linked to 5'-carbon of the sugar) and the 3'-end (the free hydroxyl group in the sugar in 3' position).
