Most proteins and peptides contain both alcohols and amino groups. Two amino acids are alkanolamines, formally speaking: serine and hydroxyproline. Veratridine and veratrine; Tropane alkaloids such as atropine; hormones and neurotransmitters epinephrine (adrenaline) and norepinephrine (noradrenaline)

A new review reports that nine people taking semaglutide and tirzepatide — the active ingredient in GLP-1 medications — experienced vision issues, including three potentially blinding eye ...
Citrulline is not one of the 20 standard amino acids encoded by DNA in the genetic code. Instead, it is the result of a post-translational modification. Citrullination is distinct from the formation of the free amino acid citrulline as part of the urea cycle or as a byproduct of enzymes of the nitric oxide synthase family.
proline. Secondary amino acids, amino acids containing a secondary amine group are sometimes named imino acids, [2] [3] though this usage is obsolescent. [1] The only proteinogenic amino acid of this type is proline, although the related non-proteinogenic amino acids hydroxyproline [4] [5] [6] and pipecolic acid [7] have often been included in studies of this class of compounds.
Nicotianamine is a metal-chelating molecule ubiquitous in higher plants. [1] It is also used as a precursor for the synthesis of phytosiderophores which play a key role in iron uptake from the soil in graminaceous plants. [2]
