What is Natural Selection?01:32

What is Natural Selection?

128.9K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Color Vision01:24

Color Vision

1.5K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Green Algae01:21

Green Algae

817
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...

Nature and Nurture

22.3K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Chirality in Nature02:30

Chirality in Nature

17.2K
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid.

Area of Science:

  • Food Science
  • Chemistry
  • Regulatory Affairs

Background:

  • Growing consumer demand for natural food colorants drives industry interest in replacing artificial pigments.
  • Stabilizing natural green hues in processed foods presents significant chemical challenges.
  • Existing strategies like metallochlorophylls and microencapsulation have limitations.

Purpose of the Study:

  • To review current strategies for stabilizing natural green food colorants.
  • To clarify the different chlorophyll compounds used in authorized green food colorants.
  • To compare international regulations and review toxicological data (ADME) for green natural food colorants.

Main Methods:

  • Literature review of scientific publications and regulatory documents.
  • Comparative analysis of global food legislation concerning natural colorants.
  • Synthesis of pharmacokinetic data on the absorption, distribution, metabolism, and excretion (ADME) of green pigments.

Main Results:

  • Green coloring foodstuffs are identified as a successful market solution for stable green hues.
  • Confusion exists regarding the specific chlorophyll compounds used as authorized green food colorants.
  • International legislation varies, and comprehensive ADME data for all green natural food colorants is needed.

Conclusions:

  • Green coloring foodstuffs offer a viable and regulated approach to natural green food coloration.
  • Further clarification and standardization of chlorophyll compounds in food colorants are necessary.
  • More research into the ADME profiles of natural green food colorants is crucial for consumer safety and regulatory harmonization.
