The chemical reactions involving UDP-N-acetylglucosamine, a substance composed of N-acetylglucosamine, a common structural unit of oligosaccharides, in glycosidic linkage with uridine diphosphate.

The process whose specific outcome is the progression of the brain over time, from its formation to the mature structure. The brain is one of the two components of the central nervous system and is the center of thought and emotion. It is responsible for the coordination and control of bodily activities and the interpretation of information from the senses (sight, hearing, smell, etc.).

The formation from simpler components of UDP-N-acetylglucosamine, a substance composed of N-acetylglucosamine, a common structural unit of oligosaccharides, in glycosidic linkage with uridine diphosphate.

Catalysis of the reaction: (3S)-3-hydroxyacyl-CoA = trans-2(or 3)-enoyl-CoA + H2O.

Catalysis of the reaction: an epoxide + H2O = a glycol.

Catalysis of the reaction: RNA + H2O = 5'-phosphomononucleotides. Cleaves RNA in the 3' to 5' direction.

The process whose specific outcome is the progression of the peripheral nervous system over time, from its formation to the mature structure. The peripheral nervous system is one of the two major divisions of the nervous system. Nerves in the PNS connect the central nervous system (CNS) with sensory organs, other organs, muscles, blood vessels and glands.

The process whose specific outcome is the progression of sensory organs over time, from its formation to the mature structure.

Catalysis of the reaction: estradiol-17-beta + NADP+ = estrone + NADPH + H+.

Catalysis of the reaction: 3'-phosphoadenosine 5'-phosphosulfate (PAPS) + estrone = adenosine 3',5'-bisphosphate + estrone 3-sulfate.

Catalysis of the reaction: ATP + ethanolamine = ADP + O-phosphoethanolamine.

Catalysis of the reaction: CTP + ethanolamine phosphate = diphosphate + CDP-ethanolamine.

Catalysis of the reaction: CDP-ethanolamine + 1,2-diacylglycerol = CMP + a phosphatidylethanolamine.

The chemical reactions involving chitin, a linear polysaccharide consisting of P-1,4-linked N-acetyl-D-glucosamine residues.
