Plastoglubuli contain both structural proteins and enzymes involved in lipid synthesis and metabolism. The resulting carbanions are key intermediates in many reactions in organic synthesis and biosynthesis. Morphological changes require pigment synthesis and degradation. Several mechanisms of organic molecule synthesis have been investigated. It also maintains protein metabolism in its synthesis and degradation. Porphyrias are caused by mutations in genes that encode enzymes in heme synthesis. This results in the inhibition of prostaglandin synthesis. It works by preventing bacteria from reproducing through the inhibition of protein synthesis. Organisms use glucose as a precursor for the synthesis of several important substances. They also produce peptides involved in ovarian hormone synthesis regulation. These two sugars act as a precursor for sucrose synthesis. It is also responsible for a large part of amino acid synthesis. Aminopterin blocks the pathway that allows for nucleotide synthesis. Codons are key to translation of genetic information for the synthesis of proteins. SMRT sequencing is based on the sequencing by synthesis approach.
