Phenylalanylisoleucine

(2S,3S)-2-[(2S)-2-amino-3-phenylpropanamido]-3-methylpentanoic acid

C15H22N2O3 (278.163)

Phenylalanylisoleucine is a dipeptide composed of phenylalanine and isoleucine. It is an incomplete breakdown product of protein digestion or protein catabolism. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Some dipeptides are known to have physiological or cell-signalling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis.

Leucylphenylalanine

(2S)-2-[(2S)-2-amino-4-methylpentanamido]-3-phenylpropanoic acid

C15H22N2O3 (278.163)

Leucylphenylalanine is a dipeptide composed of leucine and phenylalanine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signalling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. Leucyl-phenylalanine belongs to the class of organic compounds known as dipeptides.

Isoleucyl-Phenylalanine

2-[(2-Amino-1-hydroxy-3-methylpentylidene)amino]-3-phenylpropanoate

C15H22N2O3 (278.163)

Isoleucyl-Phenylalanine is a dipeptide composed of isoleucine and phenylalanine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.

keratan sulfate I

4-[(3-butoxy-4-methoxyphenyl)methyl]-4,5-dihydro-3H-imidazol-2-ol

C15H22N2O3 (278.163)

keratan sulfate I, also known as Keratan sulfuric acid I or 4-(3-Butoxy-4-methoxybenzyl)-2-imidazolidinone, is classified as a member of the Anisoles. Anisoles are organic compounds containing a methoxybenzene or a derivative thereof. keratan sulfate I is considered to be practically insoluble (in water) and relatively neutral D004791 - Enzyme Inhibitors > D010726 - Phosphodiesterase Inhibitors

2-[(2-Amino-1-hydroxy-4-methylpentylidene)amino]-3-phenylpropanoate

C15H22N2O3 (278.163)

Leucyl-phenylalanine, also known as (2s,3s)-(2-2h,3-2h)-leucine-(S)-phenylalanine or leu-phe, is a member of the class of compounds known as dipeptides. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Leucyl-phenylalanine is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Leucyl-phenylalanine can be found primarily in blood, feces, and urine. Leucyl-phenylalanine belongs to the class of organic compounds known as dipeptides.
