Fat and Protein Metabolism Oxidation Flashcards

Flashcards for Fat and Protein Metabolism Oxidation

Glycerol

Carried in blood dissolved as it is soluble in plasma as it has 3 OH group attached.

FFAs

Carried in the blood attached to protein albumin as they are not soluble in aqueous plasma.

Free fatty acids

Also called non esterified fatty acids (NEFA)

Transport of Fatty Acids to the muscle

Fats move through the blood via lipoproteins (triglycerides) or bound to the protein.

Lipid Metabolism Step 1

Breakdown of triglyceride Free Fatty Acids

Lipid Metabolism Step 2

Transport of FFA in the blood (attached to albumin)

Lipid Metabolism Step 3

Uptake FFA from the blood to muscle

Lipid Metabolism Step 4

Preparation of FA for a catabolism (Energy activation)

Lipid Metabolism Step 5

Entry of activated FA into muscle mitochondria

Lipid Metabolism Step 6

Breakdown of FA to acetyl-CoA via oxidation and the production of NADH and FADH2

Ketone Bodies production

Excess acetyl-CoA is converted to ketone bodies because not enough pyruvate is produced to maintain CAC cycle intermediates (Oxaloacetate)

Transamination

Transfer of amino group i.e. the nitrogen group to ketoregulate

Glucogenesis

Blood glucose must be maintained for brain function

Glycogen

The body’s storage of carbohydrate

Glycogenolysis

glycogen breakdown
