WebStep-by-step explanation. 1. Biosynthesis of palmitate (C16) doesn't produce 8 molecules of water (H 2 O); it produces only 6 molecules of water. It actually produces 7 molecules of water (for 7 rounds), but one molecule of water is consumed by the plamitoyl thioesterase reaction to cleave the ACP from palmitoyl-ACP to release free palmitate.

Palmitic acid is the first fatty acid produced during fatty acid synthesis and is the precursor to longer fatty acids. As a consequence, palmitic acid is a major body component of animals. In humans, one analysis found it to make up 21–30% (molar) of human depot fat, and it is a major, but highly variable, lipid component of human breast milk. Palmitate negatively feeds back on acetyl-CoA carboxylase (ACC), which is responsible for converting acetyl-CoA to malonyl-CoA, whi… WebMarilyn D. Resh, in Biochemistry of Lipids, Lipoproteins and Membranes (Sixth Edition), 2016. 2.3.1 Cell Biology and Enzymology of N-Palmitoylation. Attachment of palmitate to Shh is dependent on passage of Shh through the secretory pathway, as Shh constructs in which the signal sequence has been removed are not N-palmitoylated.
