Hyaluronidase

Hyaluronidase
Structure:  Six Hyal sequences occur in the human genome, constituting a newly recognized family of enzymes.

 
Reactions: “By catalyzing the hydrolysis of hyaluronan, a constituent of the extracellular matrix (ECM), hyaluronidase lowers the viscosity of hyaluronan, thereby increasing tissue permeability. It is, therefore, used in medicine in conjunction with other drugs to speed their dispersion and delivery. Common applications are opthalmic surgery, in combination with local anesthetics.” They have similar catalytic mechanisms that contrast markedly with the bacterial Hyals.” So the enzyme helps your body absorb medicines that are injected to your skin.


Rates: “It also increases the absorption rate of parenteral fluids given by hypodermoclysis, and is an adjunct in subcutaneous urography for improving resorption of radiopaque agents. Hyaluronidase is also used for extravasation of hyperosmolar solutions.”


Formula: C2455H3775N617O704S21


Molecular weight: 53870.9 g/mol

Picric acid - Kelsey Feltner

PICRIC ACID

IUPAC name: 2,4,6-Trinitrophenol

Structure:



 



Chemical formula & molecular weight g/mol: C6H3N3O7     229.1 g/mol                

Physical properties: Melting point- 122.5 °C     Boiling point-> 300 °C (Explodes)  Solubility in water-12.7 g/L

Intermolecular forces: Hydrogen bonding results in higher melting points and much higher boiling points. Picric acid is both a useful explosive compound and a precursor to other explosives.
