Old people often suffer from a deficiency of serotonin, an important inhibitory neurotransmitter that initiates sleep. Inhibitory neurotransmitters reduce neuron activity, in contrast to the above-mentioned neurotransmitters, which usually increase activity. Sleep disorders are common in old age, including difficulties in falling and staying asleep. Irritability and bedtime flights of ideas may occur. Tryptophan, an […]

Proteins are complex molecules, made up of amino acids, which perform a wide variety of functions in the human body, from chemical reaction-controlling enzymes, to structural molecules like collagen, to necessary components in human memory. In order to function properly, proteins must assume a correct three-dimensional configuration. In their proper shape, some proteins act as […]
