Unformatted text preview: • It is inhibited by insulin. Nonesterified fatty acids are bound to serum albumin for transport to other tissues, where they are used. • Major target tissues are muscle and liver. • At the target cells nonesterified fatty acids are taken up passively. Within the target cells they are bound to fatty acid binding protein. Next they must be activated....
