Crotonic acid has 4 carbons, is included in croton oil, and is a trans-2-mono-unsaturated fatty acid.C 3 H 5 CO 2 H, IUPAC organization name (E)-but-2-enoic acid, trans-but-2-enoic acid, numerical representation 4:1, n-1, molecular weight 86.09, melting point 72–74 °C, boiling point 180–181 °C, specific gravity 1.027.
Examples of unsaturated fatty acids are palmitoleic acid, oleic acid, myristoleic acid, linoleic acid, and arachidonic acid. Foods containing unsaturated fats include avocado, nuts, olive oils, and vegetable oils such as canola. Meat products contain both saturated and unsaturated fats.
Cis unsaturated fatty acids, however, increase cellular membrane fluidity, whereas trans unsaturated fatty acids do not. trans A trans configuration, by contrast, means that the adjacent two hydrogen atoms lie on opposite sides of the chain.
Hydrogenation of an unsaturated fatty acid is intended to convert unsaturated fatty acids (and unsaturated fats) to saturated derivatives. The hydrogenation process however can cause cis C=C bonds to become trans. Typical commercial hydrogenation is partial to obtain a malleable mixture of fats that is solid at room temperature , but melts ...
Avocados contain unsaturated fats which may be beneficial for visceral fat loss. One small study found that women who ate one avocado per day saw reductions in visceral fat, but a different study ...
Monounsaturated fats are triglycerides containing one unsaturated fatty acid. Almost invariably that fatty acid is oleic acid (18:1 n−9). Palmitoleic acid (16:1 n−7) and cis-vaccenic acid (18:1 n−7) occur in small amounts in fats.
Example of an unsaturated fat triglyceride (C 55 H 98 O 6).Left part: glycerol; right part, from top to bottom: palmitic acid, oleic acid, alpha-linolenic acid. A triglyceride (from tri-and glyceride; also TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids. [1]
Fast food gets a bad rap for being unhealthy, but there are healthy fast food options at chains like McDonald’s, Pizza Hut, and Sonic. Dietitians explain.
