− | Threonine is an '''essential amino acid for dogs and cats'''. Threonine is characterised as a '''gluconeogenic''' amino acid and contains a hydroxyl side chain which is chemically reactive. Dietary threonine is absorbed by a neutral amino acid transporter in the [[Small Intestine Overview - Anatomy & Physiology|small intestine]] (particularly the [[Jejunum - Anatomy & Physiology|jejunum]]) and plasma threonine is actively reabsorbed in the [[Nephron Microscopic Anatomy#Proximal Tubule|proximal tubule]] of the kidney. | + | Threonine is an [[Amino Acids Overview - Nutrition|'''essential amino acid]] for dogs and cats'''.
