Percentage of Free to Total Leptin in Diabetic Patients and its Correlation to Blood Insulin, Glucose and Lipids

INTRODUCTION: Leptin is a hormone resulting from the obesity gene which could be important in the pathogenesis of the insulin. Only limited data concerning the interaction of insulin, glucose tolerance and free leptin are available and no data exist on the potential influence of free vs. bound circulating leptin. We, therefore, studied percentage of free to total leptin in diabetic patients. ...

Serum eicosapentaenoic acid to arachidonic acid ratio is associated with cardio-healthy exceptional longevity.

Conversion of oleic acid to linoleic acid.

Reports from this laboratory have described the formation of palmitoleic and oleic acids from their saturated counterparts by enzyme systems of yeast (2, 3). For introducing a double bond into the 9,lO position of the aliphatic chain, the desaturating enzymes, acting on the coenzyme A derivatives of the fatty acids, require reduced triphosphopyridine nucleotide, and molecular oxygen as hydrogen...

Phosphatidic Acid, Lysophosphatidic Acid and Related Lipids

Phosphatidic acid or 1,2-diacyl-sn-glycero-3-phosphate is not an abundant lipid constituent of any living organism to my knowledge, but it is extremely important as an intermediate in the biosynthesis of triacylglycerols and phospholipids and as a signalling molecule. Indeed, it is often over-estimated in tissues as it can arise by inadvertent enzymatic hydrolysis during inappropriate storage o...

Abnormal polyunsaturated fatty acid patterns of serum lipids in alcoholism and cirrhosis: arachidonic acid deficiency in cirrhosis.

Patterns of polyunsaturated fatty acids of serum phospholipids were measured for groups of alcoholics without cirrhosis, alcoholics with cirrhosis, cirrhotics without alcoholism, and a control population. Alcoholics without cirrhosis showed increased polyunsaturated fatty acids derived from linoleic and linolenic acids, but in cirrhotics these products were decreased. Alcoholism accentuated the...
