1. Nitrogen / ATP + cAMP Flashcards
Nitrogen
1s2 2s2 2p3 Oxidation nr. -3/-5 Colorless gas No odour All organisms contain N in one form or another 78% in atmosphere Principle Bioelement Many heterocyclic compounds --> Nucleic acids!
Compounds of Nitrogen
Ammonia
- Colourless
- Sharp odour
- Polar
- H bonds dissolve in water
- Ammonium ion –> Toxic properties for animals
- can act as a weak base
Oxides of Nitrogen
N2O
NO
NO2
N2O5
Functions of NO
- Vasodilation
- Neurotransmitter
- Penile erection
- Toxic in bacteria
N2O
Laughing gas / Anesthetic
NO
Colourless, Signaling molecule, Endothelium derived relaxing factor (Smooth muscle relaxation)
NO2
Redish brown gas, Toxic in Environment
N2O5
strongly oxidizing, white chrystalline
Oxiacids of nitrogen
HNO2
HNO3
HNO2
Weak not stable acid
Organic Nitrites –> Esters of nitrous acid
Salt: NaNo2 –> Toxic : Food additive alters colour of preserved meat
HNO3
Strong acid, instable
oxidizing agent
Phosphor and Sulphur boiled in HNO3 –> Acids
Acts on all metals –> Nitrates & Oxides
NO2-
Toxic
Blue baby syndrome (Treatment of methylene blue )
Methemoglobinemia
Nitrites with secondary amines ?
Nitrosamines –> Carcinogens
ATP
most abundant free nucleotide in mammal cells
Intracellular concentration: 1mmol
Drives many Energy consuming reaction for ACTIVE transport
Metabolite
Highest ATP production in Mitochondria
Formation of ATP
Formed from ADP when full molecules are oxidized
