Document Summary
Nearest the methyl end of the carbon chain. Omega number presents location of the closes double bond from methyl end. Omega-3"s closest double bond is three carbons away from methyl end. Condensation of glycerol and fatty acids to form a triglyceride. Polyunsaturated fats tend to be liquid at room temperature. Length of carbon chain in uences degree of rmness. Diagram of saturated and unsaturated fatty acids compared. A cis-fatty acid has its hydrogens on the same side of the double bond; cis molecules bend into a u-like formation. Most naturally occurring unsaturated fatty acids in foods are cis. A trans-fatty acid has its hydrogens on the opposite sides of the double bond; trans molecules are more linear. The trans from typically occurs in partially hydrogenated foods when hydrogen atoms shift around some double bonds and change the con guration from cis to trans. Lingual lipase plays role in fat digestion in infants. Packed with proteins into transport vehicles called chylomicrons.
