What is cis-lycopene?
cis-Lycopene is the predominating isomeric form of lycopene found in blood and tissues. Our objective was to understand how thermal processing and lipid concentration affect carotenoid isomerisation and degradation in tangerine tomatoes.
What is the structure of lycopene?
C40H56
Lycopene/Formula
How many isoprene does lycopene have?
eight isoprene units
Lycopene is a lipophilic red-colored carotenoid pigment, composed of eight isoprene units (octaprene) joined by regular head to tail bindings, except in the middle of the molecule where the binding is tail to tail, giving rise to a symmetric structure (Fig.
How many double bonds are in the lycopene structure?
Lycopene occurs naturally as all trans form and its chain containing seven double bonds that can be isomerized to mono-cis or poly-cis due to the exposure to high temperatures, light, oxygen, acids, catalyst and metal ions [23].
What’s lycopene good for?
Lycopene is a powerful antioxidant with many health benefits, including sun protection, improved heart health and a lower risk of certain types of cancer. Though it can be found as a supplement, it may be most effective when consumed from lycopene-rich foods like tomatoes and other red or pink fruits.
Where is lycopene found?
Lycopene, a naturally occurring red carotenoid pigment found in tomatoes, pink grapefruit, watermelon, papaya, guava, and other fruits, has been extensively studied for more than 70 years, with more than 2000 articles published in peer-reviewed journals and 4000 other publications (scientific and otherwise) written on …
What is the molecular mass of lycopene?
536.873 g/mol
Lycopene/Molar mass
Is lycopene a phenolic compound?
Phenolic compounds are also present in tomatoes in lower concentrations than carotenoids [17] and most of these belong to hydroxycinnamic acids and flavonoids such as flavanones, flavonols, and anthocyanidins [18]. … In tomatoes, one of the major bioactive molecules present is the carotenoid, lycopene [17].
What class of biochemical is lycopene?
carotenoid pigment
Lycopene is a non-essential human nutrient that is classified as a non-provitamin A carotenoid pigment since it lacks a terminal beta ionone ring and does not mediate vitamin A activity. However lycophene is a potent antioxidant molecule that scavenges reactive oxygen species (ROS) singlet oxygen.
What wavelength absorbs lycopene?
Chem. Soc. 25 (2014) 1431. In the case of lycopene, the high-energy blue and green wavelengths are absorbed, while the lower energy red light is reflected, and so it appears red.
What is the density of lycopene?
0.889 g/cm3

Does lycopene increase testosterone?
Treatment with lycopene significantly increased testosterone levels, testes weight, and Bcl-2 mRNA expression, improved tubular structure and decreased malondialdehyde levels, BAX mRNA expression and TUNEL-positive cells.
What makes lycopene susceptible to heat mediated isomerization?
The presence of its conjugated double bonds makes lycopene susceptible to heat-mediated isomerization, which leads to the formation of 9-cis, 13-cis, or 15-cislycopene isomers, among others [2,3,4,5]. Open in a separate window Figure 1
What kind of chemical structure does lycopene have?
The chemical structure of lycopene, C 40 H 56, contains two unconjugated double bonds and eleven conjugated double bonds and provides plants, such as tomato, watermelon, and guava, their distinctive red color [2,4] (Figure 1).
How is lycopene used in the treatment of CVDs?
Lycopene can be used in different CVDs, too. It can improve ventricular remodeling, and vascular and endothelial function. In addition, it is useful in the reduction in atherosclerotic plaque size, and arterial stiffness.
Are there any beneficial effects of lycopene on the body?
It is currently unknown whether the beneficial effects are from the native structure of lycopene or its metabolic derivatives: lycopenals, lycopenols, and lycopenoic acids. This literature review focuses on the current research on lycopene digestion, absorption, metabolism, and excretion.
