The biological functions of D-amino acids remain unclear, although D-phenylalanine has pharmacological activity at niacin receptor 2. [17] DL-Phenylalanine (DLPA) is marketed as a nutritional supplement for its purported analgesic and antidepressant activities, which have been supported by clinical trials.
A phylogenetic tree showing how a number of monoamine receptors are related to each other. Monoamine neurotransmitter systems occur in virtually all vertebrates, where the evolvability of these systems has served to promote the adaptability of vertebrate species to different environments.

Dopamine is a neurotransmitter with much importance in the limbic system which regulates emotional function regulation. Dopamine has many roles in the brain including cognition, sleep, mood, milk production, movement, motivation, and reward. [12] Serotonin is a neurotransmitter that regulates mood, sleep, and other roles of the brain.
Activity at an axon terminal: Neuron A is transmitting a signal at the axon terminal to neuron B (receiving). Features: 1. Mitochondrion.2. synaptic vesicle with neurotransmitters.
Scientists have created a full map of an adult brain for the first time.. The 3D model of all of the neurons of a fruit fly, and the 50 million connections between them, is the first time that ...
Phenylalanine is a large, neutral amino acid (LNAA). LNAAs compete for transport across the blood–brain barrier (BBB) via the large neutral amino acid transporter (LNAAT). If phenylalanine is in excess in the blood, it will saturate the transporter. Excessive levels of phenylalanine tend to decrease the levels of other LNAAs in the brain.
MT-TF mutations have been associated with complex IV deficiency of the mitochondrial respiratory chain, also known as the cytochrome c oxidase deficiency. Cytochrome c oxidase deficiency is a rare genetic condition that can affect multiple parts of the body, including skeletal muscles, the heart, the brain, or the liver.
