Hey everyone, we're asked to identify whether the compounds boron try fluoride and phosphorus try fluoride are polar or non polar. To answer this question, we need to draw out our lewis structures. Starting with boron try fluoride. We know that boron is in o...
Answer to: Which of the following elements is NOT one of the top six elements in the body? a. Phosphorus. b. Potassium. c. Carbon. d. Nitrogen...
The cleavage deactivates the inhibitor. Following cleavage, the active agent is liberated into the local environment. Administration of the inhibitor alone or together with the active agent suppress the compound's activity until it reaches the proximity of a target cell. Targeted specific release ...
