Fatty acid melting points
WebJan 4, 2024 · Saturated fatty acids usually have a higher melting point than their counterparts which leads to the common understanding that saturated fatty acids remain in the solid-state at room temperatures. … WebAs the length of the fatty acid increases, the melting point of the fatty acid increases (Table 1). Conversely, the addition of double bonds into the fatty acyl chain causes the melting point of the fatty acid to decrease. This is because the addition of a double bond introduces a kink into the otherwise linear acyl chain and decreases the ...
