Answer:
2 aluminum reacts with sulfuric acid
Biologically, GSH reduces the disulfide bonds formed within cytoplasmic proteins to cysteines and reacts to other oxidized GSH to an oxidized form of glutathione disulfide (GSSG), also called L(-)-glutathione. It is oxidized by glutathione reductase by using NADPH as an electron donor
Answer:
<u></u>
Explanation:
<u>1. Calculate the number of moles of NiCl₂</u>
a) Identify the known variables
- V =0.800 liters
- M = 0.531M
- n = ?
b) Formula
c) Clear n
<u>g) Substitute and compute</u>
<u>2. Convert moles to grams</u>
a) molar mass of NiCl₂
- 129g/mol (shown in the problem)
b) Unit canceling method
Use the factors in order to cancel the units to obtain grams
Note that the mol unit appears on the numerator and denominator, so it cancels leaving just g (grams).
c) Round to 3 signficant figures
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).
