Example sentences for: aldehyde

How can you use “aldehyde” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Both MAP kinase and STAT pathways are involved in AR-dependent regulation and in ligand-independent activation of the AR [ 18 ] . Differential expression of aldehyde dehydrogenase 1A1 and alcohol dehydrogenase 1B, enzymes that affect retinoic acid biosynthesis, suggest that other signaling pathways may participate in the AR-initiated programs of external genital differentiation [ 19 20 ] .

  • Several of the differentially expressed genes, including aldo-keto reductase 1C1 ( AKR1C1 ), aldehyde dehydrogenase 1A1 ( ALDH1A1 ), and alcohol dehydrogenase 1B ( ADH1B ), function in sex steroid and retinoic acid metabolism (Figure 2).

  • Biosynthetic modifications to the periphery of the tetrapyrrole ring progressively cause withdrawal of electrons from the pyrrole nitrogens, thereby decreasing their basicity [ 20 21 ] . For example, oxidation of the 7-methyl group in Chl a to the electronegative aldehyde of Chl b reduces the pK of the pyrrole nitrogens by 2 pH units.

  • Retinoids are found in a variety of chemical oxidation states, including alcohol, aldehyde, ester, and carboxylic acid functionalities.

  • The lack of an aldehyde group on the periphery of the macrocycle of Chl c, which replaces Chl b in homologous complexes in chromophytic algae, indicates that the primary interaction between Chls and the proteins does not involve such substituents.
