R-4-phosphopantothenoyl-l-cysteine is a member of the class of compounds known as hybrid peptides. Hybrid peptides are compounds containing at least two different types of amino acids (alpha, beta, gamma, delta) linked to each other through a peptide bond. R-4-phosphopantothenoyl-l-cysteine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). R-4-phosphopantothenoyl-l-cysteine can be found in a number of food items such as peach, chia, persian lime, and yellow pond-lily, which makes R-4-phosphopantothenoyl-l-cysteine a potential biomarker for the consumption of these food products.
