Palmitic acid

palmitic acid

(Science: biochemistry) One of the most widely distributed of fatty acids.

The palmitoyl residue is one of the common acyl residues of membrane phospholipids. It is also found as a thioester attached to cystein residues on some membrane proteins. The proteins so modified are often transmembrane proteins and the modified residue is on the cytoplasmic surface of the membrane.

The specificity of the transferase for the acyl residue is not high and both stearoyl and oleoyl residues can replace the palmitoyl residue.

Compare: myristoylation.

TAG's VS GLYCOGEN

... vs glygogen it says... 1g of glucose requires 0.033 mol of O2 and 1g of palmitic acid requires 23mol of 02 so does this mean glucose is a more efficienct fuel as it needs LESS ...

Fatty acid Oxidation-ATP yeild

Ok, so it's very simple actually. the fatty acid is cut into groups of 2 carbons that are used to make acetyl~CoA. The process ... and 2 ATP/FADH2 you get 2+3+(3*3)+2+1= 17 ATP molecules. And since you took palmitic acid as an example, to find out the total ATP yield for your molecule, ...
