What is the most abundant amino acid in the human body?
Glutamine
In human blood, glutamine is the most abundant free amino acid.[6]
Alkaline phosphatase
In humans, alkaline phosphatase is present in all tissues throughout the entire body, but is particularly concentrated in the liver, bile duct, kidney, bone, intestinal mucosa and placenta. In the serum, two types of alkaline phosphatase isozymes predominate: skeletal and liver. During childhood the majority of alkaline phosphatase are of skeletal origin. Humans and most other mammals contain the following alkaline phosphatase isozymes:
Four genes encode the four isozymes. The gene for tissue-nonspecific alkaline phosphatase is located on chromosome 1, and the genes for the other three isoforms are located on chromosome 2.
