Answer:
Glycine is required for purines, aspartate for pyrimidines, glycine and aspartate for both purines and pyrimidines. The remaining amino acids are not required for the synthesis.
Explanation:
Nucleotides are the monomer for the synthesis of DNA and RNA. The two main class of nitrogenous bases are purines and pyrimidines. These nitrogenous bases require the amino acids as a precursor for their synthesis.
Glycine is the simplest amino acid and required for the synthesis of purines. Aspartate is required for the synthesis of pyrimidines. Glutamine and aspartate are required for the synthesis of both purines and pyrimidines. Lysine, leucine, alanine, histidine, methionine, tryptophan and alanine are not used as a precursor for the nucleotides.
Jaundice is a condition that causes the skin of a newborn baby to turn yellow. This happens so because babies are born with extra red blood cells. After birth, the extra red blood cells break down and release a substance called bilirubin in the baby's blood. When there is too much bilirubin in the blood, the baby becomes jaundiced. <span>This condition may last for </span>3-12 weeks<span> after birth, but as long as bilirubin levels are monitored and the baby is feeding well, it rarely leads to any serious complications.</span>
Since the liver is the primary organ for metabolism, then in the setting of liver injury there will be reduced metabolism of compounds such as hormones. If these hormones are not metabolized and degraded in the liver, then these hormone levels will increase.
<em>A particular example is that the hormone estrogen is increased in the setting of liver damage, causing males with liver failure to have feminine characteristics.</em>
