- Our body needs nitrogen because it is a crucial part of amino acids, which are the building blocks of proteins. Proteins are necessary for many bodily functions, including building and repairing tissues, making enzymes, and supporting immune function. Nitrogen is also a component of nucleic acids, which make up our DNA and RNA.

Oct 27, 2020 · While their name indicates that all amino acids have acidic properties, some have basic (alkaline) side chains that contain nitrogen. These basic R chains bind to available protons (hydrogen molecules) and so gain a positive charge.
Apr 10, 2018 · Nitrogen is essential for all living things because it is a major part of amino acids, which are the building blocks of proteins and of nucleic acids such as DNA, which transfers genetic information to subsequent generations of organisms.

As implied by the root of the word (amine), the key atom in amino acid composition is nitrogen. The ultimate source of nitrogen for the biosynthesis of amino acids is atmospheric nitrogen (N...
Mar 21, 2024 · All amino acids have the same basic structure, which is shown in Figure 2.1. At the “center” of each amino acid is a carbon called the α carbon and attached to it are four groups - a hydrogen, an α- carboxyl group, an α-amine group, and an R-group, sometimes referred to as a side chain.
More specifically, the oxygen atom in the carboxyl group from one amino acid can form a hydrogen bond with a hydrogen atom bound to the nitrogen in the amino group of another amino acid. In the alpha helix, this partnering amino acid is always four amino acids farther along the chain.
May 13, 2024 · Nitrogen-containing substances include both inorganic (ammonium, nitrate, nitrite) and organic (amino acids, nucleotides, etc) molecules. The reactions shown are oxidative and reductive (note: the oxidation number of the nitrogen atoms in the molecules is shown in red).
Different transaminases recognize different amino acids, but they all use α-ketoglutarate and glutamate as one α-keto acid/α-amino acid pair. α-ketoglutarate and glutamate, therefore play a pivotal role in amino acid nitrogen metabolism.
