- Unsaturated fat is a fatty acid in which there is at least one double bond within the fatty acid chain12. A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond2. The hydrocarbon molecules in unsaturated fats have two carbons that share double or triple bond(s) and are therefore not completely saturated with hydrogen atoms1. Due to the decreased saturation with hydrogen bonds, the structures are weaker and are typically liquid (oil) at room temperature1.了解详细信息：✕以上信息汇总借助人工智能技术，若访问原文请查看了解详细信息。

An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond. A saturated fat has no carbon-to-carbon double bonds, so the maximum … 展开
