Papaya Nectar ‐ Types of Sugars
Papaya nectar is a popular tropical beverage rich with many essential nutrients and molecules. This drink has polysaccharides, vitamins such as carotenoids, minerals, and dietary fats like lipids. Lipids are very important in the human diet because they provide the body with energy, support membrane integrity and regulate metabolic pathways. In addition, different types of fats and lipids have their own specific roles, which will be discussed further in this paper.
Types of Fats & Lipids in Papaya Nectar
There are several common kinds of fats and lipids present in papaya nectar, including triglycerides, free fatty acids (FFAs), non-esterified fatty acids (NEFAs) and sterols. Triglycerides consist of three individual fatty acid molecules linked to a glycerol backbone. The main source of dietary fat in papaya nectar is most likely from triglyceride molecules and their derivatives (FFA or NEFA). FFAs are simply single fatty acid molecules that separate themselves into the solution following hydrolysis. They are also formed during digestion by GI protease-mediated hydrolysis of triglycerides. These single fatty acid molecules can either remain dissolved in the liquid called an oil or conglomerate together in an aromatic compound known as waxes. NEFAs represent other lipid components mainly composed of monounsaturated fatty acids that arise after complete hydrolysis of triglycerides, diacylglycerols, and free cholesterol among other related compounds.
In addition to these groups, sterols make up another important group of fats and lipids found in papaya nectar. Sterols are highly unsaturated biological molecules made of two hydroxylated rings and play an important role in the maintenance of normal cell structure and double layer formation. Among the variety of sterols in papaya nectar, beta-sitosterol, campesterol, centroladone, stigmasterol and lophesterol contribute significantly to the total concentration. Beta-sitosterol is one of the most abundant sterols in papaya nectar; it helps reduce disagreeable cholesterolemia levels, reduces inflammation and promotes better circulation throughout the body. Other sterols stimulate hormones production, inhibite cholesterol absorption and lower LDL-C.
Health Benefits of Fats & Lipids
Among all types of lipids present in papaya nectar, certain mono and polyunsaturated fatty acids have significant health benefits. Monounsaturated fatty acids found in papaya nectar can help to decrease the risk of coronary heart disease and stroke, prevent obesity, improve glycemic control, reduce blood pressure and act as anti-inflammatory agents against various inflammatory diseases. Omega-3 and omega-6 polyunsaturated fatty acids, on the other hand, can help reduce the risks associated with cardiovascular diseases, tumors and arthritis while also improving immune function and enhancing brain development.  Similarly, sterols from papaya nectar can help to lower “bad” cholesterol, reduce oxidative stress, improve vascular elasticity, reduce atherosclerosis deposition and exhibit immunomodulatory effects which may result in improved resistance towards infectious agents.
This paper focused on describing the types of fats and lipids found inside of papaya nectar and discussed how each type contributes to human health. Certain mono and polyunsaturated fatty acids in papaya nectar offer numerous health benefits, helping to lower “bad” cholesterol, as well as reduce the risk of coronary heart disease and stroke. Furthermore, sterols are beneficial in various ways; they can aid in lowering LDL-C, reduce oxidative stress, improve immune response, reduce atherosclerosis and more. As a food product, papaya nectar provides a large array of nutrients and fats/lipids that can substantially contribute to healthy living.
