Amino acids are important building blocks; they play an essential role in the formation of proteins and as intermediates in metabolism. Amino acids can serve as cell signaling molecules and can regulate gene expression. An optimal amount of amino acids is essential for health. There are over 500 amino acids‚ however only 20 are commonly found. Amino acids all have an amine functional group and a carboxylic acid functional group. They differentiate from each other in their side chains. Only 10 of

for example adenosine‚ histamine‚ enkephalins‚ endorphins‚ and epinephrine‚ have neurotransmitter-like properties‚ and many additional true neurotransmitters may await discovery. The first of these families‚ and the group about which most is known‚ is the amine neurotransmitters‚ a group of compounds containing a nitrogen molecule which is not part of a ring structure. Among the amine neurotransmitters are acetylcholine‚ norepinephrine‚ dopamine‚ and serotonin. Acetylcholine is possibly the most

The most common neurotransmitters in the body are endorphins‚ epinephrine‚ norepinephrine‚ serotonin‚ acetylcholine‚ and dopamine. There are between 200-300 neurotransmitters in the human body. A lack or excess amount of these can cause problems both physically and mentally. The cerebrum‚ diencephalon‚ cerebellum and brain

Question: Describe five different organelles and their functions. Explain the similarity and differences between eukaryotic cells and prokaryotic. All eukaryotic cells‚ whether from animals‚ plants‚ protists‚ and fungi‚ are fundamentally similar to one another but different from prokaryotic cell. A eukaryotic cell contains various other organelles‚ which perform specific functions in the cell. These organelles can be organized into few basic functional groups such as genetic control‚ distribution

The relative input of a various local metabolites is coordinated to control arterial blood flow; vasodilation results from chemical factors such as decreased oxygen‚ increased carbon dioxide and increased potassium. Another local chemical mediator is histamine‚ which is released during injury or allergic reactions
