. Molecular weights of fatty acids vary over a wide range. The carbon skeleton of any fatty acid is unbranched. Some fatty acids are saturated, i.e., each carbon atom is connected to its carbon atom neighbors by single bonds; and some fatty acids are unsaturated, i.e., contain at least one carbon-carbon double bond (see chemical bondchemical bond,

fatty acid

[¦fad·ē ′as·əd]

Crude glycerin can inhibit lipolysis, causing a greater passage of unsaturated fatty acids by rumen (Krueger et al., 2010), being important to note that the ruminal biohydrogenation is only possible after the occurrence of lipolysis, as the enzymes responsible for this process act only on free fatty acids.
