Carbonyl

... than any of the hydroxyl groups inside the ring of an aldose sugar (aldose sugars like glucose do not have a hydroxyl group on Carbon 1 and have a carbonyl group instead. You need a hydroxyl group to create the phosphoester bond during the phosphorylation reaction).

First of all, I was wrong. There is a methyl group on chlorophyll a and a carbonyl group on chlorophyll b. The accessory pigments will affect the absorption of different colors of light. Accessory pigments transfer their energy to chlorophyll a. The plant you ...

Recently, I found that one of my nanoparticles (silver) could not lead to elevated protein carbonyl levels (by DNP method using ELISA) in cultured cells, though in ROS studies, it does give a positive result. Any explanation? Thanks!

... that the answers is written thare. It's all because protein has a amide group and amino acid has a carboxyl roup. Both of these groups contain carbonyl arrangements which is said to be stable to oxidation stress. Meanwhile, lipids (e.g. fatty acids) are less stable to oxidation stress because ...

... antibody pre-attached. I'm trying ELISA method for detecting protein carbonylation (a type of protein oxidation due to cellular oxidative stress). Carbonyl group (the antigen) can be found in almost all proteins, though some proteins may tend to be more carbonylated than others. In this case, one ...
