Background: Dietary fat composition is a potential major factor affecting energy metabolism. Crocodile oil (CO) is rich in mono- and poly-unsaturated fatty acids exhibiting anti-inflammatory and healing properties.
Aim: This study investigated different levels of CO consumption on alterations and expression of proteins involved in energy metabolism in rats.
Methods: Twenty-one male Sprague-Dawley rats were divided into three groups and administered sterile water (N) or different doses of CO (1% or 3% [v/w] CO) orally once daily for 8 weeks. Body weight gain, food intake, energy intake, blood lipid profiles, and serum energy-related metabolites were determined. The serum proteome was analyzed using shotgun proteomics, and the functions of several candidate proteins were classified using PANTHER software.
Results: There were no significant differences in body weight or energy intake were observed between groups. However, both CO-treated groups showed significantly decreased serum triglyceride (TG) levels (p
