The reason why phytanate cannot be catabolized by β-oxidation. Concept introduction: Phytanate is a branched-chain saturated fatty acid anion, which is the conjugate base of phytanic acid. Humans obtain phytanic acid by the consumption of dairy products, ruminant animal fats, and certain fish. Phytanic acid undergoes α-oxidation in the peroxisome, and it is converted to pristanic acid by the removal of one carbon.

Here is my literature Beta Carotene HPLC analysis graph. Can you help me explain what each peak is at each retention time? Thank You :D

I have a literature B-Carotene HPLC graph in which showcases a retention time of roughly 23.6 and 25.1. Please help me compare my two different Anti-Oxidant Juice graphs. (Attached) The juices provided are: V8 Carrot Ginger Blend and V8 Original Blend Noticing the HPLC graphs I saw no peaks for the Original Blend for B-Carotene. However the Carrot Ginger Blend showed similar peaks --> Why is this reason? Please explain in terms of Retention time and Area (Under Curve). Thank You!
